The strongest evidence of a hormonal effect of green tea came from a small cross-sectional study that we conducted among Chinese women in Singapore in which we observed a 13% reduction in estrone levels (P = 0.03) and a borderline statistically significant reduction in estradiol levels among regular green tea drinkers …

Findings suggest that intake of green tea may modify estrogen metabolism or conjugation and in this way may influence breast cancer risk.

Green tea consumption, but not black tea, was also associated with reduced levels of estrone and estradiol among postmenopausal women20. Green tea’s estrogen reduction activity may result from tea polyphenols inhibiting aromatase, the key enzyme converting androgens to estrone or estradiol21.

Red clover contains phytoestrogens, a plant-based form of estrogen, which helps to improve the hormonal imbalances caused by menopause. This tea is a delicious way to add red clover to your daily routine.

Zinc supports the stress response. Inadequate or excess cortisol (the stress hormone) affects the production of estrogen and progesterone in women. Either too high or too low levels of estrogens can cause issues with menstruation, mood swings, early menopause, infertility and more. Zinc reduces inflammation.

Zinc Can Also Help With Other Period Symptoms Like PMS Numerous studies have reported that zinc levels fluctuate with each phase of the menstrual cycle. Zinc levels seem to be lowest during the luteal phase26—the phase just before menstruation, when PMS symptoms occur.

Zinc has manifold influences on the endocrine system (Figure 1). Among them, a role in the metabolism of androgen hormones, estrogen, and progesterone, together with the prostaglandins, a role in the secretion of insulin, and a role in the regulation of thymic hormones have been reported.
