Soy contains phytoestrogens—plant-sourced, hormone-like compounds, weaker than human estrogens, that may help balance hormone levels. One group of phytoestrogens—isoflavonoids—is found in great concentration in soybeans and soy products. Isoflavonoids appear to positively influence estrogen levels in younger women. Phyto-Soy contains 48 times more isoflavonoids than comparable amounts of tofu, 25 times more than tempeh and 10 times more than roasted soybeans. NSP Phyto-Soy is certified as non-genetically modified (non-GMO). Three capsules supply 36 mg isoflavones, 28 mg of which are genistein glycosides.
