Alpha-tocopherol is an alternative name for vitamin E, which has many important functions in your body. A potent antioxidant, alpha-tocopherol protects you from potentially damaging free radicals, while also boosting your immune system to help you fight off viruses and pathogenic bacteria. It also helps your body make new red blood cells and widens your blood vessels, potentially lowering your risk of developing blood clots. The best way to obtain vitamin E, according to the National Institutes of Health, is to consume vitamin E-rich foods.
