E-400 with Mixed Tocopherols contains 400 IU of vitamin E as d-alpha tocopherol – the natural form of vitamin E. In addition, it contains 67 mg of mixed tocopherols. Mixed tocopherols are a combination of the four tocopherols present in vitamin E: delta, alpha, gamma and beta tocopherol. Some mixed tocopherol supplements may not contain all four tocopherols but instead might combine two or three in various concentrations. In rare cases, a manufacturer may market a synthetic form of alpha tocopherol by itself as a mixed tocopherol.‡

Each tocopherol is a type of antioxidant, thereby reducing the risk of cell degradation.‡

Benefits supplied by mixed tocopherols range from increased immunity to faster healing. They have also been implicated in stopping tissue inflammation. Mixed tocopherols provided a wide range of benefits, rather than just d-alpha tocopherol which is found in most vitamin E supplements.‡
