ゲニステイン

Genistein is a naturally occurring isoflavone found primarily in soybeans and other leguminous plants. It is one of the most extensively studied phytoestrogens, recognized for its structural similarity to 17β-estradiol, which enables it to bind to estrogen receptors (ERα and ERβ) and exert both estrogenic and anti-estrogenic effects depending on the tissue and hormonal environment.

In addition to its role in dietary supplements, genistein is widely used as a reference standard in analytical chemistry and as a research tool in molecular biology.

Its safety profile and well-documented bioactivities make it a valuable ingredient in products targeting menopausal health, bone density support, and overall wellness.
