Product Overview

Description
  • Non-GMO Soy††
  • Dietary Supplement
  • Isoflavone-Rich

††Not genetically modified

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 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.

Suggested Use

2 tablets twice daily with a meal.

Chronic EBV
Genistein was shown in a small study to block tyrosine kinase, an enzyme that is activated in CEBV. This product has saved me, enabling me to return to work. I've been taking it for almost two years.

No thanks - may worsen CFS, adrenal dysfunction, MCS, et al
Genistein inhibits two crucial enzymes - 3-beta-hydroxysteroid-dehydrogenase (3B-HSD) and 21-hydroxylase. These enzymes are responsible for converting cholesterol to progesterone and cortisol. 3B-HSD also affects synthesis of other hormones. Inhibiting the aforementioned enzymes has repercussions for energy production, among other things - especially if there are any other issues with synthesis/conversion of cholesterol (e.g. lacking nutrients, defective pathway). Genistein may therefore worsen CFS/adrenal dysfunction. Tyrosinase is a copper enzyme. 'Increased manganese intake impairs the activity of copper metallo-enzymes' - from The Clinical Effects of Manganese by E. Blaurock-Busch, PhD - if your goal is to inhibit tyrosinases, you could try taking manganese instead (it's cheaper). Some other options are turmeric (also inhibits tyrosinases, e.g. tyrosine hydroxylase), chick peas (aka Garbanzo Beans, contain same isoflavones, though less of). If any/all of those things cause you to feel awful - then inhibiting tyrosinase is not such a good idea and/or there's possibly an iron issue.
