🧪 Formulation Notes

Non-GMO Soy

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 dietary 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 standardized isoflavone content. This unique chemical-free process requires approximately 400 pounds of soybeans to yield just one pound of finished product.

Suitable for vegetarians.

Contains no yeast, dairy, egg, gluten, corn or wheat. Contains no sugar, starch, salt, preservatives, or artificial color, flavor or fragrance.

Not genetically modified. Soy Isoflavone level calculated in accordance with the assay method in the American Journal of Clinical Nutrition, Volume 68, pages 1474-1479, December 1998.

Additional Information

Suggested Use: 2 tablets twice daily with a meal.
