Vitamin E reacts with damaging free radicals in tissues and formsa tocopheryl radical. this tocopheryl radical will be reduced with the help of a hydrogen donor, for example Vitamin C.This way Vitamin E disables the production of damaging free radicals (the compounds formed when the body convert the food into energy) in tissues and acts as an antioxidant.
