Vitamin E is a fat-soluble vitamin with anti-oxidant effects. It has a reputation for reducing the symptoms of aging on the skin, repairing scars and scar tissue, and limiting free radical harm to the body. Environmental exposures, such as cigarette smoke, air pollution, and UV radiation from the sun, also expose the body to free radicals. Vitamin E aids in the protection of cells against free radical damage. Only natural Vitamin E is used in the production of Sona E 400. Natural Vitamin E has a bioavailability of 35% higher than manufactured Vitamin E.
