Equol

Patent Granted Equol (4',7-isoflavandiol) is an isoflavandiol[1] metabolized from daidzein, a type of isoflavone, by bacterial flora in the intestines.[2] While endogenous estrogenic hormones such as estradiol are steroids, equol is a nonsteroidal estrogen. However, only about 30-50% of people have intestinal bacteria that make equol.[3] Equol may have beneficial effects on the incidence of prostate cancer,[4] bone health [5][6] skin health and physiological changes during menopause,[7] including reducing severity and frequency of hot flashes and stiffness in the neck and shoulder.
