Genistein and daidzein are Dietary Supplements.

Genistein, an isoflavone phytoestrogen derived from soybeans, has been the focus of scientific research since 1966. Soybeans are a significant dietary source of genistein; however, the amount of soy foods necessary to meet the body's needs can be difficult to incorporate into today's diet. In Asia, where soy is a staple, the daily genistein intake can be up to 20 times that of a Western diet.

We have a highly popular prostate health product with genistein called Prostate Power Rx, formulated by Ray Sahelian, M.D.

Source Naturals Genistein daidzein phytoestrogens is made from isoflavone-rich soybean powder that yields a consistent standardized isoflavone content. This unique chemical-free process requires approximately 400 pounds of soybeans to yield just one pound of finished product.

Genistein is a type of soy isoflavone, a plant chemical that is structurally similar to estrogen and may have certain estrogen-like or estrogen-antagonism effects in the human body which makes it a complex nutrient to study. The longer chemical name is 4',5,7-trihydroxyisoflavone or 5,7-dihydroxy-3-(4-hydroxyphenyl)-4H-1-benzopyran-4-one. It is a natural isoflavone occurring in many plants known to possess various biological activities, ranging from phyto-estrogenic to antioxidative actions.
