Product Description

(S)-Equol is a naturally occurring isoflavone metabolite produced from daidzein through intestinal bacterial fermentation. It is recognized for its strong affinity to estrogen receptor β (ERβ) and is widely studied for its potential applications in women’s health, healthy aging, bone health, and nutraceutical formulations.

Due to its superior bioactivity and stability compared with traditional soy isoflavones, (S)-Equol is increasingly used in dietary supplements, functional foods, pharmaceutical research, and cosmetic formulations.
