Vitamin E is a fat soluble antioxidant vitamin that helps to neutralize potentially damaging free radicals in our body. It exists in eight different forms, d-alpha-tocopherol being the most active form and one of the most powerful biologically active antioxidants. Each form has a different level of potency (functional use) in the body. The tocopherol and tocotrienol subfamilies are each composed of alpha, beta, gamma and delta vitamins having unique biological effects, with generally declining activity; e.g. delta is far less active than the alpha form. As a supplement, Vitamin E has a number of health benefits for the body. Vitamin E is particularly important for the protection of our cell membranes as well as keeping your skin, heart and circulation, nerves, muscles and red blood cells healthy. Antioxidants such as vitamin E protect your cells against the effects of dangerous free radicals, potentially damaging by-products of your bodyâ€™s metabolism. Free radicals can cause cell damage that may lead to the development of cardiovascular disease and cancer.
