Formononetin-7-acetate is a naturally-derived isoflavonoid, which is a product of acetylation of formononetin, predominantly sourced from red clover and other leguminous plants. Its mode of action involves mimicking the effects of estrogens by binding to estrogen receptors, though with less potency than endogenous estrogens. This interaction may lead to modulation of various estrogen-mediated physiological processes.

Estetrol (E4) is a naturally occurring estrogen, which is synthesized by the human fetal liver. It acts as a selective estrogen receptor modulator with a unique mode of action differentially impacting various tissues. Estetrol selectively binds to estrogen receptors, thereby facilitating a range of estrogenic activities. Interestingly, it exhibits modest estrogenic effects on both the endometrium and breast tissue, reducing potential risks typically associated with hormone therapies.
