Equol (4',7-isoflavandiol) is metabolized from Daidzein , a type of Isoflavone (common in Soy and other foods), by bacterial flora in the intestines. Only about 30% of people are able to produce Equol naturally. Equol is reputed to be beneficial because it is a nonsteroidal estrogen. It is also reported to be helpful during menopause, an aid with prostate problems, male pattern baldness, acne, and other problems because it's a powerful DHT blocker. Current research includes finding an Equol dietary supplement.
