What Is Vitamin E?

Vitamin E is a powerful, fat-soluble antioxidant that helps protect cell membranes against damage caused by free radicals and prevents the oxidation of LDL cholesterol. The term vitamin E encompasses a group of eight compounds, called tocopherols and tocotrienols, with various subsets of each, that comprise the vitamin complex as it is found in nature. Each of these different compounds have distinct chemistries and biological effects.
