Mixed E 400 IU is mainly d-alpha tocopherol but retains a natural balance of d-beta, d-delta and d-gamma tocopherols naturally found in vegetable oils. This natural form of vitamin E has been extracted by cold pressing methods that do not damage the tocopherols. No chemical solvents are used. Natural source vitamin E, designated by the prefix D, (d-alpha tocopherol), is twice as bioavailable as synthetic vitamin E, designated by the prefix DL (dl-alpha tocopherol).

Vitamin E (d-alphatocopherol) is a fat-soluble vitamin and a powerful antioxidant, protecting cell membranes from pollution, toxins and free radicals. Vitamin E is the major antioxidant in lipid body tissues and the primary defense against lipid peroxidation, particularly in tissues that contain high levels of polyunsaturated fatty acids like the brain and central nervous system.

As an antioxidant, vitamin E may help protect against cardiovascular disease, some cancers, cataracts, premature aging and other chronic degenerative diseases. It also protects other vitamins (such as vitamins A and C) from oxidation. Vitamin E's ability to protect cell membranes makes it valuable for people in polluted environments and those with active lifestyles, as physical exertion increases production of free radicals. Approximately 400 IU of vitamin E reduces exercise-induced free radical damage and helps with athletic performance. Experts agree that obtaining adequate vitamin E from the daily diet is difficult and therefore recommend daily supplementation.

Men and women who supplement with at least 100 IU of vitamin E per day have a 37-41% drop in the risk of heart disease. CHAOS (Cambridge Heart Antioxidant Study) reported a 77% drop in non-fatal heart attacks when people were given 400-800 IU of vitamin E per day.

This form of vitamin E may be used topically on the skin. It is reported to help eliminate scarring after skin injury and sunburn. Simply cut the capsule and squeeze contents onto skin.
