Vitamin E is a fat-soluble vitamin. Fat-soluble vitamins are stored in the liver and fatty tissues. There are eight different forms of vitamin E—each has its own biologic activity. Alpha-tocopherol is the most active form of vitamin E in humans. It is an antioxidant—a substance that acts to protect the body's cells against the effects of free radicals. Free radicals are normal by-products of metabolism, but they can cause cell damage.
