Emerging research demonstrates that gamma-Tocopherol, the most abundant form of Vitamin E in the diet, has very important and unique functions. Central to these functions is its capacity to detoxify reactive nitrogen species, an especially destructive form of free radical. In addition, gamma-Tocopherol acts to trap and remove free radicals from the body in a way that alpha-Tocopherol cannot. NOW Advanced Gamma E Complex provides the necessary full range of antioxidant protection because it contains a more natural balance of Tocopherols plus a full complement of Tocotrienols. NOW's advanced formula thereby provides superior support for cardiovascular health, as well as protection for the health of the prostate and the colon. From the FDA's website: "Some scientific evidence suggests that consumption of antioxidant vitamins may reduce the risk of certain forms of cancer. However, FDA has determined that this evidence is limited and not conclusive."
