The Natural Vitamin E blend of 4 Complete Tocopherols (d-alpha, d-beta, d-gamma and d-delta) plus Vitamin E Succinate. The 4 vitamin Es are powerful antioxidants that protects against free radical damage in the body. Free radicals are implicated in more than 60 degenerative diseases from heart disease to diabetes and from cancer to Alzheimer's disease. Almost all vitamin E products in the market contain only one member of the vitamin E family which is alpha tocopherol. Growing evidence show that it may not be beneficial to take d-alpha tocopherol alone without also consuming d-gamma- , d- beta- and d-delta tocopherols. The 4 vitamin Es together provide more antioxidant protection than just 1 vitamin E (d-alpha tocopherol) alone.
