Leading the change to better periods and hormones
Body identical hormone therapy includes an estradiol patch and oral micronised progesterone. Hormones that are exactly identical to the body’s own hormones.
Progestins such as drospirenone, levonorgestrel, or medroxyprogesterone are not progesterone.
That’s because progesterone is not a generic term like estrogen. Instead, progesterone refers only to the hormone made by the corpus luteum or taken as oral micronized progesterone.
Bioidentical or body-identical hormones are estradiol and progesterone, which 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, while bioidentical is the term traditionally applied to customised hormone formulas dispensed by a compounding pharmacist when compounding was the only way to obtain such hormones.
Progesterone is usually soothing to mood but can sometimes cause anxiety.
A negative mood reaction to changing levels of progesterone is called neurosteroid change sensitivity or premenstrual dysphoric disorder (PMDD) and affects about one in twenty women.

According to a Lancet review, menstrual migraines are more severe than migraines at other times of the cycle.
Possible drivers of menstrual migraines include estrogen withdrawal at the end of the cycle, plus an estrogen-dependent release of prostaglandins and histamine. Body-identical progesterone may help to shelter the brain from estrogen withdrawal and reduce the frequency and intensity of menstrual migraines.
