Genistein, an isoflavone phytonutrient derived from soybeans, has been the focus of scientific research since 1966. Studies have shown that genistein can bind to the same receptor sites as estrogen.** Soybeans are the only 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 intake can be up to 20 times that of a Western diet.
Source Naturals Genistein Soy Complex is made from a soybean powder that yields a consistent standarized isoflavone content. This unique chemical-free process requires approximately 400 pounds of soybeans to yield just one pound of finished powder.
