What Is Bioidentical or Body-Identical Hormone Therapy?

Bioidentical hormones

Bioidentical or body-identical hormones are estradiol and progesterone that are molecularly identical to human hormones. Most (not all) modern menopause hormone therapy is bioidentical. Keep reading for a list of brands.

The difference between “bioidentical” and “body-identical” is that body-identical is the preferred conventional term and bioidentical the term traditionally applied to customised hormone formulas dispensed by a compounding chemist, back when compounding was the only way to obtain such hormones.

Today, bioidentical products are available from any doctor and pharmacy and are widely
regarded as safer than non-bioidentical hormone therapy.

Bioidentical hormone therapy is safer

Bioidentical hormones have fewer side effects than contraceptive drugs or older types of hormone therapy such as conjugated horse estrogens (Premarin®), which were popular in the 1990s.

Did you know? Premarin is an old-style estrogen drug that contains about 30 different hormones, including androgens, many of which are not body-identical. The two main active ingredients are estrone sulfate and equilin sulfate, the second found only in horses. Together, the whole compound is referred to as conjugated equine estrogens and is extracted from pregnant mares’ urine.

Modern estrogen therapy is usually bioidentical estradiol and transdermal (absorbed through the
skin) which allows it to directly enter the bloodstream and not form dangerous blood-clotting factors in the liver. The safest type of estrogen is, therefore, an estradiol patch (Estradot® or
Climara®), gel (Sandrena® or Estrogel®), or vaginal estrogen.

Bioidentical progesterone does not cause mood side effects like progestins. Nor does progesterone carry the heart disease or breast cancer risk of progestins. In fact, according to Professor Prior, progesterone may even help to reduce the risk of breast cancer

Bioidentical progesterone is available as oral micronized progesterone capsules (brands Prometrium® and Utrogestan®). All other brands of “progesterone” are actually progestins (not progesterone), and that includes the tablets Primolut® and Provera, and the patch Estalis®.

Estrogen versus progesterone therapy for menopause and perimenopause

Transdermal bioidentical estradiol can relieve hot flushes and mood disturbance of menopause. It’s safest when combined with bioidentical progesterone.

Under current guidelines, the only officially recognised use of oral micronised progesterone is as the progesterone part of hormone therapy – in other words, estrogen plus progesterone, and, even then, only if you have a uterus. As I discuss in Hormone Repair Manual, progesterone can also be used on its own (without estrogen) for perimenopausal symptoms such as night sweats, heart palpitations, sleep issues, migraines, mood problems, heavy periods. Even without a uterus, progesterone is beneficial for mood and breasts.

👉🏽 Tip: Perimenopause or “second puberty” are the two to ten years before periods actually stop. Symptoms include heavy periods, insomnia, anxiety, and night sweats, and are the result of losing progesterone, not estrogen.

adapted from Prof Jerilynn Prior’s “Perimenopause lost—reframing the end of menstruation.”

Progesterone-alone has a few advantages over estrogen:

👉 Tip: There’s no progesterone in any type of hormonal birth control.

Progesterone can also make periods lighter and is a good alternative to progestin drugs such as the pill. Bioidentical progesterone capsules can even be used together with the hormone IUD.

  1. I took Prometrium for perimenopause symptoms. I started with 100 mg for a year and then upped it to 200 mg. Over a couple of years, I just started to feel and look ‘thick’. I went off of it to see if that was the culprit. It was a little. Was I imagining things?

  2. There is a progesterone cream which says it has “Progesterone USP derived from soy.” Is that bioidentical? I don’t want to risk breast cancer.

  3. Hi Lara, I purchased your book The Hormone Repair Manual and wanted to say thank you as it has helped me a lot. I am 1 year post menopause and take 100mg Prometrium nightly and 1 Vagifem Low pessary every 5 days. I want to start Estrogel for hot flushes but am concerned of the amount of estradiol in each pump. Each pump contains 0.75mg estradiol (as hemihydrate) and my doctor has prescribed 2 pumps weekly. In your book Professor Prior says “no menopausal women should need more than 50mcg a day” but was referring to estradiol patches. Is 2 pumps of Estrogel weekly way too much estradiol? Should I just do half a pump?

  4. Doctor Briden hello 🙋🏻‍♀️🌺

    I am 48 and most likely in perimenopause stage, my cycles are very unstable from 21 to 25, 28, 30 days

    I don’t have heavy periods, but i am seeing symptoms that you described in your last book. I started taking micronized progesterone 100mg only during luteal phase to help me with sleep issues
    I don’t think i ovulate regularly ( i check for vaginal fertile mucus ) and sometimes i see mucus closer to my period. That means i have short literal phase?

    my question is if i don’t have heavy periods is progesterone still helpful? I seem to be irritated and moody and depressed now all the time. It used to be only before period.
    Shall i take it al throughout my cycle or only 14 days before period?
    My gynecologist is not on the same page with me on natural alternative approach to health but grateful that he gave me prescription for progesterone.
    He said to check my hormones by doing a blood test on third day of my period. Is that correct?
    you mentioned in your book that there is no need to check for estrogen or progesterone if a woman in perimenopause since hormones fluctuate all the time.
    I am in USA and you know how they are treating female issue here.
    thank you 🙏🏻

  5. Hi Dr. Briden !
    Will micronized progesterone pill make any negative impact on liver ? Or perhaps it’s better to take vaginal form of progesterone ? Thank you 🙏🏻

    • Oral micronized progesterone does not harm the liver. It does go through the liver but that’s usually good because it means more formation of the tranquilising neurosteroid allopregnanolone. So, oral progesterone is usually more calming and sedating than topical progesterone. And should always be taken at bedtime.

  6. Is bio identical progesterone (made by the compounding chemist ) good for joint pain in post menopause. Should I be using estrogen(as pessaries) at the same time? Thanks in advance

  7. Hi Dr. Briden
    I have your two books. Thank you. It’s very helpful. I recently was able to get micronized progesterone, I asked for Prometrium but i thought that 100mg would be a lot for me to start off, it’s my first time frankly,( i am going through perimenopause but still menstruating)
    so i asked a doctor if we can change to 50mg, prescription was transferred to compounding pharmacy, where they made it from scratch. The bottle label says micronized progesterone. So now i am little worried that this might not be a progesterone but progestin? I called the pharmacy and they said it was made from wild yam 🍠. should i go ahead and take this in the 50mg dose or better get the brand name Prometrium in 100mg?
    I don’t want to have any hormonal issues if i take that compounded formulation
    thank you 🙏🏻

      • I see, thank you for replying Lara
        I have tried progesterone cream before it seems to help a bit but not drastically.

        so … 50mg ok to start off or better get 100mg?
        I usually have sleeping issues week before period and moodiness and depression. But recently i started on St John Wort and it seem to help with depression.

  8. I have been taking estradiol gel and progesterone (Teva) for 15 years. I have had insomnia all my adult life. I am now 64. Should I stop the estradiol and just take the progesterone to help me sleep? Thank you!

  9. Hi Lara,
    Is Tibilone a progestin and is it safe when taken with Estrogel?
    I would prefer to try Teva with the Estrogel. I am post menopausal.

  10. Hello! I am 25 years old, I have high levels of androgens and low levels of female hormones. I didn’t have a period for a very long time (it has never been regular), so I started using a bioidentical progesterone cream. However, every time I start taking it (for about half a year now), bleeding starts regularly on the seventh or eighth day after I take it. Why could this be so?

  11. Hi Dr Briden, is the generic estradiol patch as good as the brands you list in your book? I’m learning so much from your wonderful book, trying to read as fast as I can as so much applies to me!

    Thank you for this life changing (and life saving) book! I’m 53, in menopause and been using Bi-est and Progesterone cream compounded. I like the idea of a patch and want to try it instead of cream, but my insurance only covers the generic patch called Dotti. Will it suffice?

    Is there any issue with using the estradiol patch and not using estriol, which my ND says helps buffer some of estradiol’s potentially negative effects? Is there a reason you do not use the compounding creams / Bi-est?

    Many thanks,

    • hi Kirstie,
      Yes, Dotti is body-identical estradiol. I think it’s fine to use straight estradiol rather than bi-est (estradiol plus estriol).
      The main reason to choose conventional body-identical products over compounded formulas is they’re easier to get and usually cheaper.

      • Thank you so much Dr Briden. You were right about it being cheaper. I just found out the generic patch is free with my insurance! I am shocked. Hoping it works out, so much savings!

        I had severe endometriosis, 8 major surgeries and 2 children (thankfully) before uterus out due to adenomyosis. I have my ovaries. Years ago OTC progesterone cream was a miracle for me.

        Would estradiol patch still be a good option over Bi-Est, due to endometriosis, etc? Currently on 1.5 mg Bi-Est and 90 mg Progesterone creams, once daily, both compounded. I believe switching Progesterone would be much cheaper too. I’m so excited to learn about this, I’m spending a ridiculous amount monthly. I cannot thank you enough.

        Is it possible to switch fr compounded 10% Progesterone to Now Brand you recommend in your book? Unsure of difference between the two.

        Based on your book, it seems I’m on very high dose of Progesterone. Having trouble finding right doses of hormones to help, which is how I found your awesome book! It is so empowering.

        Sadly, it seems most doctors really do not understand hormones (and many other issues) like you do. I wish you were taking new patients, I’d be quick to sign up! But very grateful to have the book as a guide. I’m buying my daughter your Period Repair Manual, she’s 19 and it looks just as great as the Hormone Repair Manual! 🙂

        With much gratitude,

        • Since you’re taking estrogen, it makes sense to counterbalance that with a higher dose of progesterone than you can get from an over-the-counter cream. 90 mg as a cream is reasonable in that situation if you feel well on it. Of course, speak to your doctor. I’ve just discovered that generic brand progesterone capsules (Teva) are very affordable but you’ll need a prescription from your naturopathic doctor or MD. See the “how to speak to your doctor” sections in my book about how to request a prescription for progesterone even when you don’t have a uterus. Mainly, to support sleep and/or protect the breasts.

          • Hi Dr Briden, I’ve been reading as much as I can on bioidentical estradiol patch. Is there a general conversion dose / protocol for when someone is switching from Bi-Est 80/20 to the patch? I’m guessing to start with the lowest dose of 0.025 mg, but unsure how to make switch over as far as the need to taper / and how?

            How long do you have a patient on a specific dose before deciding to increase the strength, if symptoms persist? I know you do not recommend higher than 0.05 mg of estradiol patch.

            Also, I found a Mayo Clinic study (a small one) on pharmacokinetics of the Estradiol patch compared with bioidentical compounded Bi-Est creams:

            “This pharmacokinetic trial showed that the currently used doses of compounded hormones yield lower levels of estrogen compared to the standard-dose estradiol patch.

            We observed a surprising trend toward increased E3 levels in the E2 patch group compared to the E2+E3 cream groups, which may be partly explained by endogenous conversion from higher E2 in the patch group to higher E3 levels.”


            I find this very interesting because before finding your book I had never known of the patch. The use of Bi-Est is preferred by my ND because of protective effects of E3, yet the patch looks to increase E3 even more than the cream. I shred this study with her.

            I’m a bit nervous to switch because not sure of best way and I had anxiety issues recently from too strong of Bi-Est due to COMT +/+. Have you ever had a patient have any issues with lowest dose patch? I have the 0.025 mg patch but trying to determine best way to switch. ND suggests over 9 days to half the cream 3 days, then 1/4 next 3 days, then 1/4 last 3 days then switch to patch. Does this sound reasonable?

            Sorry, so many questions, it’s overwhelming and just trying to make sense of it all. Your book is the best I’ve found on so many topics! From Sibo, to Vitamin D / K2 being more important for bone health than calcium, to magnesium helping menopause! It’s amazing and thank you for writing it and for this wonderful blog!

            Many thanks!
            Kirstie L

      • Also meant to ask what frequency of estradiol patch is safe? My ND is recommending the 25 mcg patch twice per week to start. I’m COMT +,+ and just concerned with too much estrogen – due to genetics I don’t metabolize it well.

        Thanks again for any information. Kind regards, Kirstie

  12. Thank you. Great article. Confused what Livial is and if it is bioidentical and safe to use in a healthy woman in first year of menopause.

  13. Hi Lara, I am 50 and in perimenopause. (No periods because I am on Cerazette for contraception.) I’ve finally convinced my doctor to prescribe me Utrogestan. I’ve been on it for 2 weeks now, 100mg taken daily. I’ve been suffering from hormonal migraines, hair thinning and excess facial (chin) hair for a few years now, and have also recently started to get hot flushes, and extreme fatigue late afternoons/early evenings. How long should I give the Utrogestan to start working, before I should add an Estradot patch as well?

  14. Thanks to what I’ve learned from you, I am taking oral micronised progesterone for adenomyosis and all the perimenopausal reasons you mention here, and it has helped a lot. My question is that my dr only wants me to take it in the second half of my period, after ovulation until day 1 of my cycle. Is that how you would recommend that I take it, or should I take it daily?

  15. Compounded progesterone vs. progesterone that is manufactured by pharmaceutical company??? Compounds are expensive and not covered by my insurance. I have a sensitivity to peanuts and topical transdermal progesterone and estradiol don’t alleviate my menopausal symptoms. Is there an oral progesterone that does not contain peanut oil? I am 67 and have been on hormone therapy for 22 years. I went into menopause at age 44 and still have my uterus and ovaries. My entire body benefits from the hormones. I have arthritis and without the hormones, I am in constant pain. However, my weight and edema in my legs have been and issue for 22 years due to the progesterone. What are your thoughts on cycling the progesterone, 12 -15 days on and 15 days off. I realize that I will have a slight bleed after stopping progesterone. But I have been told by some doctors that this is keeping the lining of my uterus thin and at a safe level???
    Appreciate any input as all my doctors have different thoughts…

  16. I have finally gotten a doctor to prescribe me progesterone!!
    My cycle is 26 days and he told me to take it on day 16 but reading Dr. Prior’s article I should take it on day 12 during 14 days. Is it taken after ovulation? Can you please explain this? Thank you Dr. Lara, you are an inspiration to women.

    • It’s normally best to start it after ovulation, unless there’s a reason to take it before (such as symptoms with ovulation). so, that could mean waiting till day 16.

  17. I have your hormone repair manual. I have endometriosis and also a bicornate uterus and apparently a full complete septum divide, prostap injection has been recommended prior to surgery which is a long wait. Also on 2 tablets of desogestral as I was still having a 5 day period every 2 weeks. The anxiety and mood is apparent. Would utrogestan help instead of desogestral progestin? Though I imagine if it was just endo it wouldn’t be as tricky as the bicorn and septum divide uterus which I believe adds to painful periods.

  18. What about hot flashes over 50 and past menopause when hormones cause other issues. I went off HRT 3 years ago and have suffered with sleepless nights

  19. Hello Lara! I am 47 and I am experiencing some hormone fluctuations, I think I am in perimenopause. My body temp rises for 1-2 weeks every month, starting about 10 days before periods, my sleep gets disrupted, blood pressure rises and I get horrible migrains. I’ve read your article and I am thinking about asking my gynecologist to prescribe progesterone (I have uterine fibroids). However I’ve read the study that concluded that a combination of pregesterone and estrogen increases the risk of breast cancer much more than the estrogen alone. It was a meta-analysis published in the Lancet entitled “Menopausal hormones: definitive evidence for breast cancer”. It got me thinking that it may be progesterone that is responsible for the increased risk. What do you think about it? Thank you so much for your wonderful blog!

  20. Hi Lara. My ob is putting me on prometrium, but my pharmacy filled my prescription with a generic brand called Bionpharma. Do you know if this progesterone is bio identical? I’ve experienced 4 mc and I just want to do all I can if I’m blessed again. Thank you🙏🏻

    • There are generic brands of progesterone. What does the label say, exactly? (Bionpharma is just the name of the pharmaceutical company)

  21. Hi Lara. Would it be better to take progesterone capsule internally rather than orally? I decided to be back on BHRT but this time take the gentler dose of 25mcg estradiol. I was wondering if l still need 100mg progesterone for 14 days with much lower estradiol dose as l want a cycle, or can l simply lessen the amount of progesterone take days to 8 or 10? I would really prefer to take it vaginally. What do you suggest? Thank you Lara.

    • Hi Lara I’m 65 years old and have been taking Angelique for 5 years but only one tablet every 3rd day but I still have night and day sweats but if I take them on a daily basis they make my breasts swell dramatically and they become very painful. Should I continue with Angelique or change to something else.

  22. Hi Lara, I’m 54 and still having irregular periods.
    I am using emerita progestin and estriol cream.
    The estriol has soy in it. I’m allergic to soy. It causes eczema for me. I have been using the estriol for 2 weeks now and my eczema is really bad right now. I stopped last night. Today I am researching and reading your sites on estrogen. The Estrofem tablets, I can’t find the ingredients to see if it is soy free. Do you have that information? Would you recommend that or a estrogen cream?
    I want to be prepared before I see my doctor soon.
    Thank you!

    • Emerita products contain biodentical progesterone, NOT progestins.

      I’m confused why Dr. Lara wrote: “Bioidentical progesterone is available as oral micronized progesterone capsules (brands Prometrium® and Utrogestan®). All other brands of “progesterone” are actually progestins (not progesterone), and that includes the tablets Primolut® and Provera, and the patch Estalis®.”

      Actually, topical (not oral) bioidentical progesterone is readily available from not only Emerita but from Bezwecken and some other manufacturers, as well as from compounding pharmacies. I’m sure Dr. Lara is aware of this, but she didn’t include these brands in her list, possibly because they are not mainstream prescription pharmaceuticals that are covered by insurance.

      Whatever one thinks of these products, as a simple factual matter, it’s just not true that “all other brands of ‘progesterone’ are actually progestins.

      At any rate, there appears to be more solid information in general on this site than can be found in most places on the internet, and I appreciate that. It’s always good to find sites to recommend to my own patients.

      • Elene hi 👋🏻 i recently was able to get prescription from Prometrium 100 mg based on Lara’s book suggestions to deal with my perimenopausal symptoms mood, anxiety and sleeping issues (48 yrs old still menstruating) but i thought 100mg to start would be a lot, it’s my first time, so i asked them to change to 50mg. And my prescription was sent out to compounding pharmacy where they prepared oral micronized progesterone for me. Now my concern is if it’s safe to take? Since it’s not a brand name, it’s compounded, etc . I don’t want things to get worse for me if i start this? Would Prometrium brand name in 100mg would be better then compounded..? What is the difference? Are the made the same? Thank you 🙏🏻

  23. Complete hysterectomy and years of side effects after going off Estratest form of hormones to many different forms of bioidentical hormones. Recently discontinued Bio EST/TEST injections and switched to compound estrogen and DHEA (testosterone is still high and have facial hair but no libido) Progesterone is making me feel more calm but still waking at 2-3 AM and have MCAS, and have gained 12 lbs in 6 weeks with changing to compound estrogen, DHEA and adding progesterone along with also severe migraines. What am I missing? hormones continue to confuse me.

      • Hope this finds you as my reply as I cannot find my post from earlier today. I am taking an OTC called Forefront Health Molecular Progesterone complex in MCT and Vit E oil (each drop is 3 mg) I am taking 3 drops, 2-3X a day. It has me more calm in the day but not helping at all with night waking and up in weight. RX BIEST (Estriol/Estradoil) SR dye Free 0.25mg/0.75 mg) 1 am
        RX DHEA SR 25 mg capsule 1-2 am

        I also take Levoxyl. We have no doctors in our area who understand hormones.
        Incidentally since stopping the injection of Estrogen/Testosterone I am up in weight and my libido is totally gone

  24. My Functional Dr has prescribed bio identical hormones, estradiol cream, testosterone cream and Prometrium that i take vaginally. Are you saying taking only Progesterone is enough? Im 54 and check my hormones every 3 months. My levels are OK. It was hard to increase testosterone.Thanks.

  25. Hi Lara. I have premature ovarian failure. I am 38 and l m not having periods since 6 years. I was diagnosed when 32. I was on body identical HRT for 9 months this year however l stopped them to see if l would be ok without them and the truth is l am. I have no symptoms, l feel great, mood is much better than it was while on body identical HRT. My question is am l risking my bone, heart, brain health because l am not on HRT? I ve been told to use it till my natural menopause age which is for 12 years. I am really confused about what to do. I eat very healthy, take calcium, ( egg shell powder) magnesium, Vit D and K2 supplements for bone health. My memory was sharper while on Climara patches but l am not having any brain fog and l am generally doing fine.
    Thank you.

    • the short answer is yes. With premature ovarian insufficiency and without hormone therapy, you will be at higher risk for osteoporosis, heart disease and other conditions. If you had mood side effects from the hormone therapy, can I ask what type, dose etc you were taking? Was it transdermal estradiol and a progesterone capsule like prometrium?

      • Thank you Lara. I was on cyclic BHRT. Climara patch 50 mcg and Utrogestan capsules 200mg x2 for 14
        days each month. I could not tolerate Utrogestan orally and was advised to use it vaginally. Yes it was progesterone that l had issues with. I ve read a very interesting article regarding HRT and Osteoporosis l would like to share with you the link if you don!t mind. https://www.chantryhealth.com/hrt-osteoporosis/?fbclid=IwAR3m2so-PBom258iUH_cNWx55VmcZtb70ArhKjDMHzVSuddMCv65Z__iLMo

        • I discuss the pros and cons of hormone therapy in more detail in my new book Hormone Repair Manual.

          In general, I agree that most women who undergo normal menopause at about age 50 do not require hormone therapy. Premature ovarian insufficiency is different.

          And for what it’s worth, you were taking a dose of hormones 4 times higher than I might recommend. A gentler dose (and a common dose) is 25 mcg estradiol and 100 mg progesterone. At that level, there are not usually side effcts.

          • Thank you Lara. I m a member of many POF support groups and many women there are on 100mcg patches which they are told this was the dose they needed till age 50. It s quite a lot. I will get a bone scan soon and if my results come bad l might be back on BHRT. I will definitely go for the 25mcg patch this time. I m sorry about a mistake l made earlier on. I took 100mgs x 2 capsules of Utragestan for 14 days so 200 mgs each day.

          • Prof Jerilynn Prior (who helped me with my books) says women should never need more than 50 mcg. And I find 25 seems to be a good dose, even for women with POF. Especially, if it’s a question of “take a high dose that causes side effects” or “take nothing.” There’s a middle ground of using a smaller dose that actually feels good.

  26. Hi Dr Briden. I had a hysterectomy 3 years ago at 49, due to large fibroids. Only one ovary was removed. At the time my periods were normal and no obvious signs of perimenopause. Through this past year I have been getting alot of anxiety and possibly a bit of depression. My doctor say’s it’s a mental due to COVID, (yes time for a new Dr) and I’m wondering if’s it’s menopause? I have no hot flashes at all, but my sleep is sometimes affected with 3-4am wakeups. How can I find out if it’s caused by menopause?

  27. A clear article Lara. So just to clarify. If you have been taking magnesium taurine and b12s for a couple of weeks but are now adding daytime flushes to night sweats is it time for the bio identical progesterone? Do you need to cycle it? Mine has missed a cycle and still waiting or can you take it right through?

  28. I’m very confused by this statement: “Estrogen does not drop during perimenopause but instead, rises to up to three times higher.” I was tested and my lab results came back ‘low estrogen’, can you please explain this a bit further so I can have a better understanding? I’m interested in body identical HRT, but I want to make sure I’m getting the correct dosage. My Dr. currently wants to prescribe both estrogen and progesterone and if you are saying estrogen is already high during perimenopause period, I’m not sure if I want to even take estrogen. Thank you.

  29. I am 45 and in perimenopause and have PMDD and the instructions for taking micronised progesterone are from day 15 in the cycle. I am not sure if I am ovulating, so I have bought a clear blue test kit to help me know. So far I have just taken it on day 15 as instructed….but then I had a thought. This makes the assumption that I am ovulating on day 15 and it maybe that it occurs later than that. Would it not be better to wait till ovulation and THEN start taking the progesterone? So as to keep with the rythmn of what my body is doing? Or to put it another way…..does it mess up my cycle to assume I have ovulated and start the progesterone? (Trying not to anger the hormone gods….PMDD and Peri not fun)

  30. Hi Lara.

    I love your blogs they are extremely informative. I am 50 and starting to be quite affected by my perimenopause symptoms. Particularly now the broken sleep and night sweats. Although they are not extreme. I have also noticed very low mood and not interested in much which can not happen with three early teen kids. I have graves disease and avoid dairy and gluten as much as practical. I take 55mg of b6 along with 3 and 12. What is the type of magnesium and taurine that you recommend. Would you still recommend starting on those before progesterone for my mood?

  31. My dr are prescribing 100 mg utrogestan continously for perimenopausal symptoms, or 200 mg cyklical for two weeks out of the month. Am 50 and sometimes have 40 or more days inbetween periods. How to know when to take it cyklically then? I am so confused. I have histamine problems and about to treat Lyme. She say I can try either and see which way Suits me best. I have never heard of taking utrogestan each day throuhout the month. Would that be alright and ad can I swtich from taking it vaginally to orally?

  32. Hi. I am 39 and stopped birth control 3 months ago, I haven’t had a period since and had bloodwork taken this week. My estrogen is low, my progesterone non existent and my FSH is also in post menopause range. My FreeT4 was lower than normal range also. I have gained 15kg over the last 9 months and generally feel sluggish and unmotivated to exercise – yet my diet has not changed. According to my blood work it appears as if I am post menopause. Is this something that can change the longer I’m off the pill?

  33. Lara,
    I have a question I had an ophorectomy in July and for the last 5 weeks have been flashing all day and night and no cycle for 9 weeks I am 49 my doctor prescribed Climara 0.025 patch and Prometrium 100 at night. I still have one ovary and no hysterectomy so I’m wondering if this will be the right combo for me? Thanks so much for any advice!

  34. I’m wondering how does taking bodyidentical progesterone affect a regular cycle during perimenopause? During the follicle phase my sleep is poor while it’s much better on the luteal phase. My gyno suggested taking utrogestan (100mg), starting from day 2 – up until ovulation. I’m a bit hesitant as I don’t want to lose my cycle. What’s your experience, how does taking progesterone affect the cycle when taken in the follicle phase? Many thanks!

  35. I tried clamara patch. I did biest cream and oral Progestrone. All of it made me sick dizzy head pressure and vibrations. I know it has benefits but I’m lost. I stopped everthing because I couldn’t function.

    • see my blog post Rescue prescription for menopause. With my patients, I start with magnesium + taurine for a few weeks, then add progesterone cream, and only then think about adding low-dose transdermal estrogen but keeping the magnesium and progesterone in place. But speak to your doctor.

  36. Hi Lara!
    Thanks for bringing those issues to the point.
    I am from Germany, 45 years old and after a partial emergency hysterectomy entered perimenopause.
    It took 8 months where I felt terrible and no doctor had a glue what was wrong.
    I was prescribed antidepressants and spent weeks in several hospitals.
    For my luck finally one doctor agreed to my wish to make a hormone blood test and I was able to find an endocrinological gynecologist.
    It seems I am deeply into at least perimenopause.
    I am now on a small amount of an Estradiol gel and Utrogest 200mg.

    I wished women would be taught about all those things like we are visiting classes for delivering babies.

    Thanks for your part on making that happen!!!

    Yours, Bianka

    • Blanka,
      There is a great FB group called Bio-identical Hormone Replacement Therapy which is really informative about menopause & BHRT. Many women have had surgery as well. We all are proactive in tackling this hormone stuff. Thought you might be interested!

  37. Anyone from the U.K taking body-identical hormones? I’d be grateful if you could share the brand names/what kind of medication you’re taking. I was diagnosed with Premature Ovarian Failure 6 years ago, aged 22, and I’m looking into treatment for this.

    Thank you,

    • Hi Fatima, I use utrogestan (bio-identical progesterone). I’ve also been offered estradiol which is bio-identical estrogen in a cream form, but I didn’t take it because I think my estrogen levels are the problem in that they’re too high. Anyway, hope that helps! Violet.

  38. Hi Dr Briden,
    I am 38 years old, and about 10 days ago I had a full hysterectomy. I am due to have a follow up appointment with my Dr in a few weeks, but the idea of HRT seems a little scary to me.
    I am quite interested in the idea of natural therapies, but there is not a lot of options for young women going through surgical menopause.
    Honestly, I am very overwhelmed by the whole thing!!
    Do you have any suggestions on where to start?

    • Hi Kate,

      There is a really informative FB group called Bio-identical Hormone Replacement Therapy. Very educated women sharing information on BHRT, menopause, effects of surgery. it is a great place to learn about options and the various pathways to take to manage natural hormone replacement. I thought you might like to check it out.

  39. I recently had a DUTCH test and my E3 is almost undetectable and bi-est cream is being recommended. I currently take 100mg of compounded progesterone. Will the cream help? I have insomnia, no libido, anxiety,and generally feel so blah, unmotivated, foggy, headaches. Recently, AFib showed up on a test also so I’m not sure if its related to hormones. I’m 53 and in recent surgical menopause from surgery/chemo. Thanks for a great book!

    • Hormone therapy is generally recommended after surgical menopause and the best kind is transdermal estradiol with oral natural progesterone capsules.

  40. Hi there. Thanks for the post. Just a question on the types if that is possible. You mention the 3 oestrogens to take, but Vagifem is vaginal so that would not have the effect on mood and sleep would it? As it only has a local effect? Then Estradot is a patch and the Sandrena is a gel with much higher amounts. Is Sandrena still ok? As I see you mention Vagifem and Estradot more? And is there a reason why Sandrena is at 1mg up to 0.5g whereas estradot is only 25 ug. Then on the progesterones, is urtogestan any different to prometrium as again I see you mention this more. Then is teva ok as I read some reviews that it is the weaker version of prometrium and some even say the synthetic form, but there is less information on this. Thanks Susan.

  41. How about Chasteberry plus from Metagenics? Ot just Chasteberry in general? I tried BHRT and had a horrible time with side effects.

  42. FWIW I tried Prometrium – full dose and half dose – and I had a hideous time with it.
    I saw a different hormone specialist and now take compounded progesterone and it is worlds apart. Finally it does what it’s meant to do and without the nasty side effects of Prometrium. Makes me wonder what ththey’re putting in that product that would cause such a reaction.

  43. Do you know of any significant difference between the Brand Prometrium and a generic progesterone made by BionPharma? My doctor insisted on the generic, but I noticed that both Prometrium and the generic inserts have all sorts of side effect warnings. Does the FDA have to list the warnings because they lump progesterone in with synthetic progestins? I am very confused and concerned. I am 46 and showing signs of perimenopause.

    • yes, exactly as you said. “The FDA lists the warnings because they lump progesterone in with synthetic progestins.”
      And the generic one should be fine as long as it’s oral micronised progesterone.

  44. Hi Dr. Briden,

    I am not in perimenopause but I am 31 with irregular periods and I am trying to conceive. I have been diagnosed with “lean PCOS” by my doctor but I will be doing the Dutch test soon to further investigate this diagnosis. Every couple months that I don’t get my period, my doctor prescribes Provera to give me a breakthrough bleed. Do you suggest that I inquire about Prometrium instead? Or is this just for perimenopause?


    • Prometrium can be used by young women for the progesterone-challenge bleed. And see the section in Period Repair Manual about “cyclic progesterone therapy” for PCOS.

  45. Hi Dr. Briden,
    I’ve read your book and spent hours perusing your blog posts, clicking link after link. Every time I think I may have found the answer, I realize most of the symptoms don’t apply, and I move on. I’m 36 and have had 4 babies in the past 6 years. I’ve breastfed them all, so no breaks of any type in between. Currently nursing my 15 month old.
    My period returned 8 months ago without fanfare, though perhaps a little heavy. After a few normal cycles, my symptoms began- very high anxiety and panic attacks, shorter cycles (23-26 days), brown bleeding on the first day, heart palpitations. The thing is, my symptoms are the worst during my period and for about a week after. From ovulation up until my bleeding begins, I feel “normal” again.
    A doctor prescribed bioidentical progesterone cream, but he did not check any hormone levels. I am supposed to take it daily, plus try it during moments of high anxiety.
    Are there any specific tests you might recommend I request, links you could direct me towards, or other ideas? I feel like there’s more to it than this.
    (Thyroid function is fine, I don’t drink alcohol, no breast tenderness, no insomnia or night sweats, no PMS, no period pain…)

    • Hi savanah, I am 37 and my youngest child is 4. I literally could have written your post word for word. I feel like I am losing my mind the week of and a few days after my period. My cycle is similar in length too. Have you benefited from the progesterone cream? How are you doing now?

      • Hi Shay! The progesterone cream has helped, but not solved everything. This past cycle was 28 days, bleeding was much lighter, and postmenstrual period was still not great but not downright awful. I also started seed cycling about a month ago. I’m not sure what the right answer is, but I’ll continue its use for now.

  46. Hi Lara, I’m trying to figure out what to ask my Dr. for. I’m 47 years old, I’ve had one period in the last 7 months and it lasted two weeks, but it wasn’t nearly the fire hose situation it’s been in the past, thanks to the supplements listed in your book. My periods were a bit irregular before that 7 month span, with terrible pain, headaches, and hemorrhaging. I’ve been given a compounded progesterone with a small amount of testosterone in a cocoa butter base to use vaginally twice daily. It only helps with the hotflashes if I use it under my tongue at night though. My Dr. says she doesn’t want to use the micronized progesterone capsules because they have peanut oil (I’m not allergic to peanuts) and she says vaginal is better (but that doesn’t work so I’m taking them orally). Should I try the Miconized pills instead? Taking it orally has helped with the hot flashes, and some of the mood and stress, however I’m really thick around the middle and and I’ve gained a lot of weight. I’m sure I’ve got insulin resistance that I’m working on with diet and exercise. I have all the symptoms of insulin resistance you list in your book. Should I get rid of the testosterone in the compound? Should I add a bit of estrogen yet? My blood work says estrogen is normal levels, but I still have vaginal dryness, and ZERO sex drive. Thank you for your help!!!

    On more question! I’m having a lot of breast pain. I’m taking a supplement with Kelp, Kombu, Wakame, Dulse, Fennel, and Irish Moss. I have Hashimoto’s and I’ve been told to avoid too much iodine. Would it still be better to switch to iodine? Thanks again! And thank you for writing your next book!

  47. Hi Dr Briden

    Thank you because I’ve just had a sublime luteal phase thanks to following suggestions in another of your articles and taking 100mg of utrogestan, along with vit b6, taurine and magnesium. I only regret not having tried it sooner.

    I stopped taking the utrogestan the day my period arrived, but now on cycle day 4, I find I’m very low, tearful, short-tempered and stressed, so wondering if actually I’d be better taking the utrogestan etc., daily, perhaps breaking on my ovulation days? Any advice would be gratefully received.

    The lack of womens’ health practitioners and resources in the UK is woeful. I have a very nice GP who is completely supportive of anything I want to try (mostly what I find out from your posts – I’m about to go and download your book), but I can’t help feeling it’s like the blind leading the blind, and it’s very disheartening.

    Thank you for sharing all that you do. I hope you’re safe and well.

    Kind regards,


  48. Hi there. Thanks for the post. Just a question on the types if that is possible. You mention the 3 oestrogens to take, but Vagifem is vaginal so that would not have the effect on mood and sleep would it? As it only has a local effect? Then Estradot is a patch and the Sandrena is a gel with much higher amounts. Is Sandrena still ok? As I see you mention Vagifem and Estradot more?

Then is teva ok as I read some reviews that it is the weaker version of prometrium and some even say the synthetic form, but there is less information on this. Thanks Susan.

  49. I’ll try that combination. Is it possible that I need a higher dose of Estrogen (I was given the lowest dose) or that it takes a few more months before it improves? Or perhaps it’s not BV after all. The pH is always normal and lab test showed normal flora repeatedly, but my Gyn insists that it is BV.

  50. I am trying to reduce it because it didn’t seem to work, although it may have helped a little. I still had a lot of burning and discharge, but little less of the other irritations. I worry about taking estrogen for life. I would prefer getting rid of the BV first. But Flagyl and boric acid didn’t help. I tried oral and vaginal probiotics and a candida diet without success.

    • The thing is that for menopausal women, a vaginal estrogen probably is the best way to get rid of BV. The best is probably a combination of estrogen and the vaginal probiotic I describe in my book with the strains Lactobacillus rhamnosus, GR-1 and Lactobacillus reuteri, RC-14.

  51. Look into these:
    Good Love Balance gel. Vinegar plus water recipe for vagina use helps give the right pH to encourage good microbes. Get unsweetened yogurt and smear it around. Coconut oil will kill a lot of microbes, only best if you have high yeast. Use a suppository with probiotics Good for female—you can insert it or open an smear it around. If you have histamine intolerance, learn how to manage it. @histaminehacker

  52. I have a lot of vaginal issues (burning, discharge, irritation as if something is in there). My GYN (menopause specialist) says I have BV and need vaginal estrogen for life to balance the microbes. The vaginal estrogen helped minimally after 3 m. But now that I tried to reduce the dose by half, it is getting worse. Is there another way to balance the vaginal microbes?

  53. Do a search on ChrisKresser.com for osteoporosis. You will likely find these suggestions for prevention: Lower or eliminate grains due to phytates which bind to minerals when they are in your gut with your food. Take bone broths or collagen. Optimize your calcium to magnesium ratio. Eat enough protein. Get fat soluble vitamins D3 and K2. I also take Pure Encapsulations Mineral 650 and I add 15 mg of zinc. Also, do weight bearing exercise plus walking or other exercise. Broccoli is one of the plants with highest BIOAVAILABLE calcium.

  54. My mother died of a heart attack. I’m not having many symptoms (I last had a period 4 months ago, and before that, it was pretty regular. I’m 50) but wonder if there would be a reason to do something like an estridiol patch for heart reasons and osteoporosis. (My mother also had that and my bones are tiny.)

  55. Hello, Lara
    I started taking magnesium pills but I got an allergic reaction :(, I got eczema on my face skin.
    what should I do about them?

  56. Hi! Your book was a big eye-opener for me. Can you recommend anyone in Sydney or Switzerland for (suspected) post-pill pcos? Thank you so much

  57. Hello, my mom is 69 years old and now days still suffering from hot flushes, not sleeping, joints pain, etc. I would like to know your opinion about her starting to take magnesium and progesteron ❤️
    We are waiting for your book translate in spanish.
    Thank you very much

  58. Yes. So I can’t continue to take progesterone. What alternatives would you suggest?
    Also can estrogen be taken safely without progesterone?

  59. Is there a herbal alternative to Prometrium? I’m now postmenopausal; my progesterone levels tested very low, but I can’t tolerate taking Prometrium due to the hideous fatigue and depression it is causing even at a half dose. I’m also taking a 1/4 troche (1mg oestradiol + 2mg oestriol) daily. Thank you.

  60. Most informative thank you. Re starting estrogen you say in the first year of menopause… is that one year after last period? To have an idea around timing. I ve started already on progesterone cream made from yams…it is helping for sure but maybe not enough?? My sleep is barely happening! Am taking Dormidiana…is this a histamine? Does help sleep for sure. Is this ok? Thanks. Like the article above.

  61. Hi Dr. Briden. My last period was in March and I started on continuous HRT in July. Estradiol patch plus 100mg of progesterone. My dose of estradiol has been increased to .05 and symptoms are improving. I just got a period today. I’m sure it’s a period because I felt it coming with all of the other bodily signs that I normally experience before my period starts. Is it ok to be on continuous HRT if I just had a period? Is this normal?

    • It’s not unusual to get the odd period during the year or two when periods are stopping, and most doctors say to continue HRT. Best to check with yours.

  62. Is there great risk to not taking hormones at age 48 after a total hysterectomy which occurred at age 43? I took compounded cream hormones for a couple of years, but then stopped.

  63. Dr. Lara,

    I took progesterone 200mg on the last two weeks of my cycle due to heavy periods and bloating. I saw a huge difference, I was retaining liquids, and with the progesterone I felt lighter and my heavy period was lighter too. The only is that when I stopped taking progesterone I got bad headaches, it’s been a week that I’m with headaches. I thought it was a tooth I was having problems, but I think it might be cesation of progesterone intake. Could that be possible ? Should I try 100mg instead of 200mg (I;m 40 years old)?

  64. Hi Dr. Briden. I’ve recently started on Prometrium 100 mg and Estradiol patch .0375. I see you recommended taking a few days break about once a month. Can you please elaborate on that? Does it matter when and if I’ve only been on these for a couple of months should I wait to take a break?

  65. Dr Briden,
    Thank you for your work and for writing your book. I have a few questions:
    Can a 66 year old balance her hormones if she has never done so in her life time? I was diagnosed with Hashimoto’s about 10 yrs ago. But just recently am experiencing many itchy hives on my upper arms and upper back. In addition see more dark spots on my face, and arms and am very tired. I am wondering if Synthroid and Cytomel thyroid medications are not enough and a small dose of iodine might correct my problem? I have just learned of estrogen excess from your book and also realized my histamine issue has escalated recently. I am allergic to aspirin and have a touch of asthma. Are these symptoms related to estrogen excess and histamine sensitivity? My weight is the highest its ever been and I am always depressed. Can you explain what you think I might be dealing with, without an official diagnosis? I understand the limitations through this comment format.
    Thank you,

  66. Hi Dr. Briden,
    despite the hormones they gave me a few months ago not being bio identical, would you consider them equally safe? You haven’t heard anything of using phytoestrogens like red clover, horny goat weed, kudzu, etc. to help with the maintenance of bones?
    I do eat well over 200g of carbohydrates and have no vitamin or mineral deficiencies according to my blood tests, yet my estrogen is still drastically low.
    I have not read the book, but I have heard it’s an excellent read.

    • Large doses of phytoestrogens do not help hypothalamic amenorrhea and in fact, have an anti-estrogen, ovulation-suppressing effect. (small doses from food are fine)

      Are you eating 2500 calories per day?

      And in answer to your question, the safest protocol for short-term hormone replacement for HA is body-identical hormones.

  67. Hi Lara, does that mean yes, still safe or you don’t really know as studies have not been done. thanks, would love some clarity on this.

  68. I was prescribed topical estrogen gel and a progesterone tab just 8 months ago when i discovered I had osteoporosis to preserve my bone density until I get my period back. I have been suffering with HA since 15, and I am 26 now. I broke my hip 10 months ago which is how we found out about the osteoporosis.
    My question is, is HRT safe? I’m still a bit confused after reading this. I stopped the HRT 4 months in, afraid, and am now taking red clover extract because I have found studies it helps with bone density in menopausal women, despite the fact I am not kn menopause.
    Do you have some insight?

    • The current protocol is to give body-identical hormone replacement (Estraderm patch plus Prometrium) during the recovery phase of HA or RED-s. And I think that’s a reasonable thing to do short-term.

      But, of course, the more critical part of the plan is to recover your cycles by increasing your food intake at least 2500 calories per day plus 200 grams carbohydrate. Have you read “No period, now what?” by Nicola Rinaldi? Once you’re cycling, you won’t need the hormones.

  69. Dear Doctor,

    I am seeking information about progesterone use for a post menopausal woman (I am 76). I have fatigue, abdominal weight gain, hair loss that’s getting worse, and sleep issues. My DUTCH test showed I have very high DHEA and testosterone.

    Like so many people with adrenal fatigue issues, mine stemmed from a period of severe stress that I hope will be getting better. I have been symptomatic for about three years now. Before that, I was in perfect health.

    What do you think about progesterone for a woman my age? What should I read to find out more about progesterone, DHEA, cortisol and testosterone for a woman my age? I don’t have any medical background but I am passionately interested in getting well and living a healthy life.

    Love your work and I am so happy to find you. Wish we lived on the same side of the world! Many thanks and please keep me on your mailing list.

    • Hi Emily.

      I think it’s unlikely that progesterone would be the right treatment for you at 76. Especially since you say you were well three years ago (at 73) and were obviously well past menopause then. I would instead consider looking at magnesium and B-vitamins and other ways to stabilise the HPA axis.

  70. Hi I’m a 53 old women and lately I’v been experiencing hot flashes and aches in my joints. It’s really bad with joints because I suffer from EDS and my joints are very unstable and aches a lot. But it’s so much worse now. I suffer from really bad headache when I get flushed. It’s terrible so I wonder if I start with progestrone now. Can I do even if my period not regular anymore? Can you start even if you don’t have first date of your menustration. And which products can I find on line??

  71. Dear Dr. Lara Briden,

    I am 44 years old and for the last 4 years have been telling my GYN’ that my hormones are off and now I am almost bald. My hair is thinning so badly, and no one can figure it out. My GYN says to wait on the Endo, the Endo wants me to be off Spiro and Progesterone pill before he will check my blood, I went to HTR and got the progesterone but gave up on it as its very expensive. I am at my witts end and don’t want to lose my hair. I came across your post/blog and I think you have me pegged. Here is what I take, 200mg Progesterone at night, multi vitamin, Spiro 100 MG for hair loss and Viviscal Pro. I have been treated by my primary, derm, endo, and I am at my limit of giving up and totally losing my self esteem. Please help. Would love to speak with you

  72. I am 60 & well & truly post menopause. My Dr did bloods to check hormone levels & both progesterone & estrogen are practically nonexistent. I have gained too much weight & skin so dry nothing helps. My moods fluctuating as well, feeling unusually down & sad. I work full-time in a high stress (sedentary) job. My diet is 95% veg but crave carbs/sugar at night. Should I take progesterone?

    • At 60, you’re probably quite some time after menopause. I would be more tempted to look at something like magnesium to help your body cope with stress. Read 8 ways magnesium rescues hormones.

      Also, you’re not vegetarian, are you? The zinc, vitamin B6, and taurine from animal protein can be important for mood.

  73. I take Estrodial transdermal gel. It’s not on your list of recommended brand names. It says it’s estrodial, the ingredient. Same thing?

  74. Morning Laura,
    I am 50, allegedly at peri stage.
    However at the time I was vit D deficient, vegan, (previously vege since aged 10) low weight thus I believe this can mimic menopausal traits?
    My sleep patterns are erratic, I am now taking magnesium 500mg.
    The lifestyle I lead is still vegan, exercise most nights, drink 3-4 lites of water daily.
    My doctor has prescribed estradot 50mg and crinone gel 8%.Prior to that I was taking evorel which produced the most low to high moods since being a teen!!!
    Is this the best way to go?

  75. I take 300 mg progesterone and 2MG0.5ML BIEst. Now at age 59 I have been on this for 10 years. My saliva test was high in progesterone. How long do I continue on these prescriptions?

  76. Hi Lara, I am 44 and have all the symptoms of low estrogen, apart from sore breasts from around ovulation to day one or two of my cycle. I find this confusing, as painful breasts are a sign of high estrogen correct? Would I benefit from a progesterone cream? and if so, when would be the best time to use it? thanks

  77. We just decided to go off both BIO EST/TEST for 8 weeks and tried compounded Pregnenolone 25 mg, and Compounded Progesterone (blue dye allergy). After two days, very overly emotional, worse insomnia and irritability? I am in dire need of resolving acute INSOMNIA and new hot flashes at night. My first try at BIO EST/TEST injections resolved all of these symptoms for 4 weeks but then was inconsistent. I’d love to figure this out. My practitioner is open to suggestions

    • If you stopped estrogen cold turkey, then you could just be having symptoms of estrogen withdrawal. In general, it’s better to wean down estrogen.

  78. Thank you for pointing me in the right direction! I’d like more info on histamine foods, too. Is it possible to correct the imbalance through diet alone?

    • Jane, I have histamine intolerance, and I have found that as I have gotten my histamine under control and possibly my gut is actually healing, I have had much calmer PMS which I used to think was PMDD, because mainly I only ever got dysphoria, brain fod and memory problems plus fatigue. So, definitely mood and cognitive symptoms. So, I’d love to share resources for histamine reduction. You are welcome to email me and I would tell you what I have done (except I’ll have to shorten it from the real story,but I still have many good ideas to share and you can just choose what sounds right to you). I’m NOT a practitioner, I’m just a patient with some success. Rachel @ Rachel Ernst dot com

  79. Hi Laura, in light of the recent warnings about HRT do you still stand firm in these protocols- i.e. prometrium being safe as a progesterone and estradot as estrogen or do they cause breast cancer so we should not use them . Thanks, so confused after all the press today. Josie

    • perfect timing with your question. I’m just reading the full article now.
      They do not provide any stats at all for Prometrium-only treatment or for specifically the combination of Prometrium plus low-dose transdermal estradiol.

  80. Thank you for your work! I recently purchased your book and am looking forward to reading. I have one question I’m hoping you can answer.

    Background: I am 48 years old with a diagnosis of AUB, no hyperplasia (normal uterine biopsy and ultrasound–except for small fibroid–within the last 6 months). For the past 6 – 12 months, I have begun having period flooding, long periods, and erratic cycles (anywhere from 3 weeks to 9 weeks apart). My doctor prescribed Medroxyprogesterone a few months back, but I have not yet taken it due to concerns about serious and unpleasant side effects. I have a followup appointment this week and plan to discuss with her the possibility of taking Prometrium or other body-identical progesterone instead.

    My question: I still have a concern about side effects of body-identical progesterone. Websites including iodine.com, medscape, and WebMD list many of the same serious side effects & risks for Prometrium as for Provera, including blood clots, stroke, breast cancer, and liver disease. Can you please comment. Thank you!

    • Despite growing evidence that progesterone is much safer than progestins, almost all sources list the side effects of progestins as the side effects of progesterone.

      I hope this will change one day in the near future but it’s a relic of the old paradigm that progestins are the same as progesterone.

  81. Thank you for your work! I have bought your book and looking forward to reading. I’m hoping you can help me with one question.

    Background: I’m 48 and have been having flooding and erratic cycles for around 6 – 12 months. Endometrial biopsy & ultrasound both normal within the last 6 months; diagnosis = AUB without hyperplasia. My doctor prescribed Medroxyprogesterone, but I have elected not to take it due to concern about the many serious & unpleasant side effects. I have another follow up appointment with her this week and plan to discuss your recommendation of body identical progesterone.

    My question: There seems to be a lot of contradictory information about possible side effects of Prometrium. Sites including Medscape, iodine.com, and WebMD list for Prometrium many of the same side effects as for Provera, including blood clots, breast cancer, and liver disease. Can you please comment.

  82. Hi Dr. Briden~

    Your Period Repair Manual has been a bible for me and a much appreciated resource when I came off the pill at 35 and wasn’t getting my period back- thank you!

    Now nearing 40, I have kept diligent track of my BBT and charted my cycles in that time and have noticed an overall trend of what appears to be “luteal phase defect” – I typically don’t ovulate until day 20-25, and then my temperature rise only lasts 8-10 day before my period, with spotting before my periods. So overall a normal length cycle, but only 1/3 of it in luteal phase! (My periods are very light, and have been ever since they resumed post period.) Could body identical progesterone help me, and if so what days would you recommend taking it? Thanks so very much!

    • yes, the luteal phase can shorten during perimenopause, and yes, taking progesterone during the luteal phase can help with symptoms.

  83. one of my peri symptons is joint pain, not sure what causes that? as I am still having my period
    this summer I noticed my 25-27 day cycle has been lengthened to 30days , this month 35days, joint pain are getting worse. use to have very heavy period, so been put on progesterone, and it lightened my period somewhat, but still heavy, I start to take curcumin supplement, and I noticed
    my period is less now, I remember you mention about how turmeric can lighten up periods, but like to know the underlying mechanism, can you explain that to me thanks

    • Biodentical estrogen took away all my joint pain.
      Progesterone made it worse.
      I am 49 and in menopause, run long distance, lift weights, play like crazy with my four year old son, could not do it without my estrogen cream

      • thanks for sharing your story.
        It’s definitely true that estrogen can be helpful once in menopause and that some women do not feel well with progesterone therapy.
        Fortunately, many women DO feel very well with progesterone.

  84. Can you comment if one has been on all 3 bio hormones and wanted to try progesterone again, would it be safe to discontinue bio estrogen/testosterone without having menopause symptoms? I’d like to ask a practitioner about trying progesterone alone due to MCS/histamine problems mainly. I would not enjoy the return of hot flashes etc however….thank you Dr Briden. Loving this thread!

    • Testosterone can usually be stopped any time with no problem.
      Estrogen is addictive, so it may need to be weaned down. In other words, stopping estrogen suddenly could cause hot flashes.
      Normally, progesterone on its own can help to some degree with hot flashes. But may not be able to compensate completely for a sudden drop in estrogen.
      But check with your doctor, of course.

  85. In my 40’s I was oestrogen dominant with fibroids, heavy periods, flooding etc. Now 53, still having periods although in the last couple of months have been less regular (used to be 28days). Obviously peri-menopausal now but symptoms such as hot flushes, sleep disruptions are minor but still around as I have overhauled diet and supplements. Interestingly I am getting sore swollen breasts, which I haven’t had for some years. Having read your blog and website, I am wondering if I would benefit from taking progesterone. What are your thoughts?

  86. I was just recently diagnosed having simple hyperplasia not atopic. I’m 43 and my doctor wants me to use the Mirena IUD and or a progestin pill only for this. I asked her about using a body identical progesterone instead and she there is no such thing. Would a body identical/micronized progesterone help in this situation?

    • Body-identical progesterone (Prometrium or Utrogestan capsules) can be an option for some types of hyperplasia, but not all. Best to check with your doctor again but don’t use the word “bioidentical.” Instead, just say Prometrium if you’re in the States or Utrogestan in the UK.

  87. Hi Lara

    I’ve been taking magnesium, taurine & B6 as your book suggests, and am now thinking about progesterone.

    Do you find taking it cyclically can help with symptoms all month, or mainly just on the days it’s taken? My most intense symptoms are in the first half of my cycle (anxiety, low mood, brain fog). I do have some of these premenstrually too, and guess more progesterone could help then. But could it also help pre-ovulation, if I wasn’t taking it on those days? Or if not, is it an option to take it continuously?

    For background: I’m 48, having very light periods anything from 18-35 days apart. Apparently still ovulating more often than not (I take my temperature). I often feel hot, but not full-on flashes like many people describe.

    Thanks for any thoughts you have!

    • The half-life of progesterone is 3 to 90 minutes, so it is eliminated fairly quickly. And no, we don’t store it.
      We make it every day for the luteal phase and then none until the next ovulation.

  88. I’m 39 and have had only one working ovary since I was a teenager. In my early 30s I was diagnosed with PMDD and used symptom tracking to pinpoint my triggers- dropping estrogen after ovulation sends me into tailspins. Usually my moods pick up right as my period starts and estrogen starts to rise again, but I think my estrogen isn’t picking up quite like it used to. I’m having longer and heavier periods, hot flashes, headaches, and am still depressed at the beginning of my cycles- whereas I used to be super happy at that time (yes, I had good moods during my period!) With my PMDD, is progesterone really the best choice for me in perimenopause? Or am I going to need estrogen soon, too? Thank you for your help!

    • That is me exactly. The dip after ovulation is hardest. I’m best from cycle day 4 to 9. I’m 38 years old with history of damaged ovaries from stage 4 Endo. After failing miserably on a trial of Zoely pill the doctor suggested, I recently went back to normal cycles for many months and had a test showing normal testosterone, low estrogen and low progesterone on my cycle day 21 (for me that’s day 17). Now on compounded creams to give me more progesterone, but boost estrogen too. I’ve had PMDD, vaginal atrophy, fibromyalgia and interstitial cystitis all get worse in my 30’s.

  89. Hello Lara and thank you for your blog. Is it safe to try progesterone therapy for improving stress tolerance and sleep while still having ovulatory cycles and producing good amounts of progesterone (according to blood test and a naturopathic doctor)? Thank you very much!

  90. Hi Dr Briden,

    Could you please write about sensitivity to progesterone?
    I was recently prescribed 100mg of body-identical progesterone capsules to treat anovulatory cycles.
    So far I’ve taken it for my past three cycles, and each time it has given me insomnia, anxiety, & leaves me feeling groggy, dizzy & low energy. I just don’t feel like myself when I’m on it.

    Thank you.

    • I am allergic to progesterone.
      To the point where my tongue and lips swell.
      Severe depression, joint pain, l cannot tolerate any biodentical progesterone or synthetic.
      Biodentical estrogen has been my lifesaver.
      Menopause Taylor on YouTube talks comprehensively about the side effects of progesterone, real eye opener as it’s pushed as a miracle.
      It nearly killed me, looks like it’s something genetic perhaps

  91. I took 100mg for migranes during the luteal phase and it helped but didn´t stop them. I started taking 200mg and the ovulation & pre period migranes stopped. Why not try upping it to 200mg and see what happens?

  92. Thank you for this.
    The generic HRT approach is quite significant I think – as we all had/have different amounts of hormones anyway before any fluctuations or change. Do you agree?
    Still so if i understand you, staying on a progesterone + oestrogen HRT would be reasonable bet? I have been on this for 4 years since starting to be perimenopausal 4 years ago. I have refused the mirena coil plus oestrogen only as i do not want a coil inside me.
    Thirdly .. I wanted some testosterone as part of my repleacemnts as we also lose that but nothing is available apart from a gel, no controlled amount and possible side effects of permanent voice change… what are your thoughts on the inclusion

    • It’s true that our hormones fluctuate when we’re still cyclic and making our own hormones. But there is no logical way to mimic that. And I’m not even sure that would the right approach.

      At this stage, my best understanding is what I’ve described in this blog post. 1) that we start by taking progesterone-alone because progesterone is beneficial and is safer than estrogen, and 2) take a small amount of transdermal estradiol if needed for symptoms. Start low and only go up if needed.

      As for testosterone, I’m very leery of it, given the new research that menopause is already a state of relative “testosterone dominance” and that testosterone can promote insulin resistance in women.

  93. I had Mirena implant a few years ago due to menorrhagia and endometrial hyperplasia. Bled non-stop, terrible mood swings and acne from it, so out it came. Fast forward and I am now experiencing much heavier bleeding, irregular cycles, hot flashes, waking for the day at 2am, weight gain, low mood. I am 41 with endometriosis that has left me with part of one ovary. Just asked dr to prescribe me prometrium and instead they will only prescribe progestin in oral, shot, or implant form, which obviously did not go well before. What can I do to get some relief for what seems to be perimenopause/estrogen dominance? And why only progestin rx from dr?

  94. It was day 21 or 22. The ideal time for the test to be taken. I don’t have any other symptoms for low estrogen other than low libido, weight gain (quit a bit (10 lbs) and fast in the last 3-4 months, with no diet or exercise change), feeling a little blue at times, but that is it. No hot flashes or vaginal dryness. But I do spot pink before most periods for about a week in the mornings only. Like it looks like I’m getting my period but I’m not.

  95. Also… thank you for your work! It has helped me feel a sense of direction. I guess I’d just like to know if you think that I should be looking into hormonal replacement therapy based on my age and current symptoms.

  96. I am 37 and I read your book. I was told that my last two miscarriages were because of chromosomal abnormalities and after testing learned that I likely do not have many viable eggs left and the doctor labeled me as “perimenopausal” I tried to see a midlife specialist at the advisement of the fertility doctor to learn about how to keep an eye on my hormones and see if I need hormonal replacement therapy to help prevent osteoporosis or heart problems that could occur from my hormones being “off” at an early age. The midlife doctor insisted that I don’t need to see her until a year after I stopped having my period. My periods are still regular but went from 28 day cycle to 23 day cycle and are fairly light. Who should I be seeing to manage my care? I have no idea where to begin. Should I just ask my PCP to help with this?

  97. Just wanted to say thank you for all the research and information you have provided over the years. You have helped me conquer the pain of endometriosis and subsequent flooding. Progesterone is a good send and so are you! Keep up the incredible work. You are making a HUGE difference in people’s lives, especially mine. 🙂

  98. Hi, Dr. Briden

    can you tell me if zinc increase level of testosterone in your body? and is there any other way to minimize the up and downs of hormone during perimenopause? I am taking
    100mg Prometrium, helped somewhat, but still got lots of peri symptom,
    my ND thinks it caused by the fluctuating level of estrogen,my MD suggested BC pills, which I turned it down. my estrogen level are on the low side from the test i did. but my ND said there must be a surge of my estrogen at some point of my cycle, as my period is on the heavy side.


    • See Chapter 10 of Period Repair Manual for an entire section about “the estrogen rollercoaster” of perimenopause.

  99. I´ve finally managed to obtain Utrogestan for cyclical migranes and I take 100mg in the morning and 100mg before bed for 14 to 15 days. I´ve had no migraines what so ever so I am thrilled, thank you for this information.

    HOWEVER I have started to suffer from severe acid reflux during these days and I have read that hormone changes can cause the lower esophageal sphincter to relax causing acid reflux.

    Has anyone else suffered reflux once they started taking Utrogestan?

    I wonder whether taking them vaginally would help?

    I´m thrilled I´ve lost the headaches but this heartburn and reflux is also a pain.

    • I suspect it’s the morning dose giving you problems.
      Your doctor might be open to you switching to only a bedtime dose (100 or 200 mg) but talk to her, of course.

  100. I have been given compounded bioidentical forms and just progesterone with doses between 25 mg to 400 mg (gall bladder removed at this dose doctor felt progesterone caused this) also have many mast cell issues. Would love to figure this out after many functional MD’s have tried many different regimes. Complete hysterectomy early 40’a due to bursting cysts on ovaries and repeated hospitalization with kidney infections. Also periodic kidney stones. Have Sxs of estrogen dominance and low estrogen

    • With my patients in a similar situation, I start by treating the mast cell issues (with, for example, dairy-free diet, vitamin B6, quercetin). And maybe give iodine to stabilise hormone receptors.

      Then start with low-dose oral progesterone — and no other hormones.

      But check with your doctor, of course.

  101. Hi Lara, I am going to start prometrium soon. 200 mg My hormones were tested. I have estrogen that is off the charts. Progesterone is at high end of normal. Horrible insomnia, bleeding, acne, receding gums, and headaches. How long should I go between hormone re-tests? How long should I be on it in general?

    Also wondering about cancer risk with body identical estrogen for women when it is needed.

    How long should a woman generally be on all of this? How many years after menopause?

  102. What is your opinion about using bio identical hormone therapy in early 30s to regulate cycles when a person has pcos with extremely long cycles read more than 3 months without periods?

  103. Compounded, body identical bioidentical forms (I have tried many!) have the opposite effect on me. They cause puffiness, irritability, insomnia, weight gain – I’d love to hear what a person does as my practitioners have no answers. pregnenlone it’s precursor does the same.

  104. Thank you!! I take zinc. I’m 46 and not ovulating a whole lot. No bc pills. I didn’t know about insulin resistance. That’s certainly not worth it. I’m thin, but my fasting glucose is high. Thank you.

    • So much would depend on context — the age of the patient; if she’s still ovulating; what other symptoms are present; if she’s on the pill (all hormonal birth control suppresses androgens).

      In general, I am not a fan of testosterone or DHEA supplements for women because they might cause or worsen insulin resistance. But there could be some circumstances where it’s appropriate.

      General nutritional support such as zinc can support DHEA production from the adrenal glands.

  105. Hi Lara, great post as always!
    What is your thoughts on normal progesterone (meaning ovulation occurred) but very low estrogen in the early 40s. Shown from a Dutch test that it’s post menopausal levels of estrogen. Testosterone perfect as well as DHEA.
    Thank you for any insight!

    • Really, by definition, if you can reach ovulation, then you have enough estrogen.
      On which day of your cycle (relative to ovulation) was that “low estrogen” reading sampled?

  106. What do you do for low testosterone that’s not DHEA? Low libido has been an issue for years, tested very low testosterone. Sorry, not original poster, just curious.

  107. Hi Dr. Lara, I purchased your book and found it to be helpful, even purchased 1 for my neighbor. I am 54 with PCOS had horrible heavy periods only my last 2 years, other than that ! had periods every few months sometimes going for 1 yr without, I had ablasion done about 3 years ago so no periods anymore, I now have night sweats, hot flashes, irritability, mood swings, anxiety and weight gain around the tummy, also exhausted constantly, when I get up and all day long, nothing helps. I have always been chubby due to the PCOS now it is going more towards the tummy, I feel awful like I don’t want to get up in the morning, too tired.
    My gyno isn’t much help, she is always pushing something to purchase, she sells a lot of products, supplements, etc. She had me taking prometrium which was giving me nightmares now I am taking biodentical progesterone pills, 200mg and she just gave me an estrogen patch, I didn’t start it yet because 1 of the side effects mentioned weight gain, I cant have that. She told me to purchase ashwaganda, and an adrenal fatigue product from her. So far nothing has made a difference. My primary care doctor gave me metaformin to take for PCOS, I took that years ago and cant decide if I want to start again, of course I was also given birth control pills for PCOS and took them for years.

    I am miserable and the doctors around my area could care less about PCOS, I think it is not an expensive disease, and there is no cure for it so they don’t bother with it.

    Any help, suggestions would be so appreciated,

  108. I am 62 and have been on bio identical hormone‘s since age 58. I had been in post menopause since age 52 . I started the Wiley protocol which consist of bio identical estradiol, progesterone and testosterone. You mentioned the risk for heart disease. This concerns me greatly because of my age I will also mention that I have periods again. Every month like clockwork. My naturopathic doctor has 80-year-olds on the Wiley protocol. This is the same bio identical hormone‘s Recommended by Suzanne Somers. Can you give me some advice on this? What are the cardiovascular risks and why is there a greater risk for this. Younger women seldom have cardiovascular disease and yet hormones are raging in their bodies. Are there any other risks of bio identical hormone usage in older women ?

    • Thanks for commenting. This is an important part of the discussion.

      I do not recommend the so-called Wiley protocol of high dose hormone cycling because really do not like the idea of using such high doses of hormones that women keep bleeding! (They’re withdrawal bleeds– not true cycles.)

      With regard estrogen and cardiovascular disease, the current understanding is that estrogen capsules can carry a clot risk BUT that estrogen generally helps to protect against cardiovascular disease. It’s all about the dose and the timing.

      Finally, I have concerns about testosterone for women. There’s some evidence that it can promote insulin resistance and abdominal weight gain.

  109. Curious why so many doctors still refer to Progesterone as the “PMS hormone,” and use that as a reason why they typically don’t prescribe body-identical progesterone on its own?

  110. I am a huge fan of your work, Dr. Briden. I recommend your book all the time to friends. I am 44 and started 100mg of progesterone during my luteal phase for PMS and insomnia. It has helped so much! But my functional medicine doctor suggested I increase my dose to 200mg/400mg to help manage my menstrual migraines. Are there any risks to increasing it so much? Thanks!

  111. I’m 44. I did 3 months of lupron injections last year and this January had a hysterectomy..including the removal of both ovaries. The reason for this was adenomyosis and the mast cell disorder I have. I was having severe allergic reactions before and during my periods. The assumption is that I’m allergic to my own estrogen…maybe progesterone too. I’m hating the insomnia and weight gain since surgery and have thought of trying progesterone cream. Any thoughts?

  112. Hello, I`m 57 and post-menopausal around 53. I haven’t been on hormones accept some over the counter progesterone cream. I have vaginal dryness and UTI’s. I do have hot flashes but not as severe as a few years ago. I was thinking of asking my Dr. to prescribe bioidentical estrogen and progesterone. From your article it sounds like I`m to old to start them. Please tell me what you think. I really feel like I need something now. Should I just do progesterone?

    Thanks, Robin

    • You’ve only been in menopause for 4 years so you’re probably still in the safe window. But check with your doctor.
      Also, if it’s vaginal estrogen you’re thinking of, there’s no age limit for that. Vaginal estrogen is safe at any age. I should add that to the post.

      And just a tip: don’t use the word “bioidentical” with your doctor. Better to say something like “I’d like to try a vaginal estrogen.”

      Assuming she prescribes Vagifem, it is bioidentical or body-identical.

  113. I am 46 and a few years ago I began having very heavy periods with severe flooding and very short cycles, which have been helped by taking 200mg of micronized progesterone (cyclically) as well as some of your other supplement suggestions. However, I still had long, somewhat frequent periods with moderate flooding at least one day per cycle. About 2 months ago I had a Mirena IUD inserted and although spotty, I seem to be bleeding less and my NP says to be patient, that bleeding should decrease even more after 3 months.

    I reduced my progesterone dose to 100 mg, still cyclically, but I LOVE my “progesterone days” (sleep, reduced anxiety, etc.) and would like to take it continually so long as it’s safe (also considering the small amount of progestin acting locally in my uterus).

    Are there any considerations in combining Mirena with natural progesterone?

    Should I confirm that I’m having consistent anovulatory periods (by monitoring temperature?) before taking progesterone continually?

    What do you think about taking a 100 mg dose for days 1-14 and a 200 mg dose for days 15-28?

    My NP is not very knowledgeable about the benefits of natural progesterone (and didn’t understand why I wanted to continue taking it in addition to having the IUD inserted), but she has been open-minded to prescribing it as I wish.

    Thank you Dr. Briden for providing this amazing resource! I also loved your book.

    • Both good questions.
      In general, it is fine to take Prometrium along with hormonal IUD.
      As for continuous dosing, yes, that is usually fine for someone in their late-40s (and probably not ovulating very regularly anymore). But, of course, do speak to your doctor.

      thanks for commenting.

  114. Your articles are so helpful Lara – thank you. Do you have any advice for someone whose GP won’t prescribe progesterone and is pushing HRT instead? Unfortunately we are in an area with very limited doctors available, so changing GP sadly isn’t an option. My symptoms have improved with taking Mag+Taurine, DHEA-7 and Ashwagandha but feel I could still do with some extra support and would love to have options. Thanks so much!

  115. I’ve started using progesterone cream 3 months ago. I’m 45 with a monthly bleed (albeit, much lighter now) but I’m showing so many signs of low estrogen. I’m considering to go to a progesterone/ phytoestrogen cream (red clover) I’m not sure if I need bio estrogen yet. How do you feel about phytoestrogens?

    • In general, phytoestrogens are beneficial. Before menopause, they have an anti-estrogen effect.
      After menopause, phytoestrogens can a mildly pro-estrogen effect but it’s mild. And may not be enough to relieve dryness or flushes or insomnia.

  116. Thank you!! The hormone profiles are so expensive here in the US.

    Also, thank you for not using scare tactics to convince women that hormone therapy is the ONLY way to go. I’ve read so many books/watched videos by doctors who tell women that if they don’t use some form of therapy during peri- to give years post menopause they will develop some awful life-threatening chronic disease. Is there a difference culturally between the rest of the world and the US? It seems that many doctors based on the US use fear based tactics to convince patients to take drugs/unnecessary therapies. Been thinking of this a lot lately.

  117. I finally found a wonderful Dr knowledgeable about women’s hormones – yay! I had a hysterectomy about a year ago at age 38 due to adenomyosis and a rare uterine anomaly that caused pain. Based on my symptoms and family history of early menopause (mom was age 40 when she completed menopause), we both think that I am in perimenopause. I have been prescribed Prometrium for symptom management. We are starting at a dose of 200mg (which I know is a bit higher than your recommended 50-100mg starting dose) due to my severe insomnia and anxiety, night sweats, and endometriosis diagnosis (endo was excised at same time as hyst for adenomyosis).

    My questions:

    1. When is continuous dosing with bio-identical progesterone generally recommended vs cyclical dosing? I had to pour through Dr Prior’s website, and it sounded like migranes, perimenopause, and endo are times when perhaps daily dosing is warranted – is that correct?

    2. Would a daily dose suppress ovulation?

    • more than 200 mg per day can potentially suppress ovulation, but that’s not always a bad thing with endometriosis. Also, if you’re now in your 40s, then you might not be ovulating regularly anyway.

      Short answer: it can be okay to dose daily (continuously) if that is what your doctor prescribed.

      Other situations would call for cyclic or luteal phase dosing only.

  118. What about just using progesterone cream? I can’t afford to go to the doctor and have my hormones tested. I have in last years, but unless something shows up as “low,” doctors aren’t keen to prescribe anything. I have anovulatory cycles more often than not now. Thank you –
