Isoflavones have a big impact in reducing the risk of blockage of blood vessels, bone, breast and prostate cancer and reduce symptoms of menopause.

The content of iron know 33.8% of daily value. Iron is used primarily in the formation of red blood cells (hemoglobin), compounds that play a role in energy production by cells distribute oxygen throughout the body. Formation of hemoglobin also requires copper minerals. Without the minerals copper, iron can not be used in hemoglobin. Mineral content of copper in the know 11% of daily value. Besides important in the formation of hemoglobin, copper also acts to reduce the risk of symptoms of arthritis / rheumatism. Along with manganese, copper is an essential cofactor in the oxidation of the enzyme superoxide dismutase. This enzyme function are inactivated free radicals produced by mitochondria during the oxidation process to produce energy. Every 100 grams contains 34.5% out daily value of mineral manganese.

Selenium in 100 grams of 14.4% of daily value. Selenium is needed in antioxidant system to reduce the level of free radicals in cells. Selenium functions as a cofactor glutathione peroxidase, the most important antioxidant produced by the body.
