Natural anti-androgen supplements reduce testosterone or block its effects. In women, androgen blockers can improve the symptom of unwanted facial hair (hirsutism), usually associated with PCOS.
Symptoms of low estrogen include fatigue, weight gain, hair loss, depression, insomnia, dry skin, recurrent bladder infections, and vaginal dryness. Of those symptoms, vaginal dryness is the most characteristic sign and is diagnostic of estrogen deficiency.
Phytoestrogens are a special group of phytonutrients that occur naturally in most plant foods. The two major classes are isoflavones in soy, and lignans in seeds, whole grains, legumes, fruits, and vegetables.
They’re called phytoestrogens because they interact with estrogen receptors but they’re not estrogen. In fact, they bind so weakly to estrogen receptors that they effectively block estradiol and are therefore better classified as anti-estrogen.
