Blackmores Vitamin E is a natural vitamin supplement. Vitamin E is a fat-soluble antioxidant directly involved in preventing free radical activity and lipid peroxidation (damage of polyunsaturated fatty acids on cell membranes). The effect of vitamin E on the skin and blood vessels is based on its antioxidant effect. Free radicals may arise from normal basic metabolism as well as other lifestyle factors such as exposure to smoking, alcohol consumption, preservatives in certain foods (such as nitrates), ozone, chlorine, rancid foods, and excess dietary fat. A diet rich in polyunsaturated fats increases the need for vitamin E.
