How it worksPhyto-SERM Supplements

Phyto-SERMs are plant-derived, nonsteroidal compounds that bind to estrogen receptors. Isoflavones, the main group, bind more strongly to estrogen receptor beta than to estrogen receptor alpha and can act as estrogen agonists or antagonists. For DT56a (Femarelle), a tofu-derived extract, tissue-selective activity (estrogen-like in bone and vascular tissue but not in the uterus) has been shown mainly in studies of rats and cultured cells.

Weight Loss

Women with obesity are more likely to report frequent and severe hot flashes than women of normal weight, and body fat appears to act as a risk factor for hot flashes earlier in the menopause transition. Losing weight through behavioral changes in diet and exercise may reduce hot flashes for women who are overweight or obese.
