Planetary Formulas Soy Genistein Isoflavone Powder is a highly concentrated, non-GMO, isoflavone-rich soy powder, specially prepared from soy germ. Unlike many soy products, which are by-products from the manufacture of soybean oil, this is specifically designed as a health supplement yielding low amounts of phytic acid. Epidemiological research in Asia shows that a diet rich in soy isoflavones has significant health-supporting benefits, especially for women. Specifically, they support immune and cardiovascular health and are beneficial during and after menopause.
