Vitamin E is a mixture of several related compounds known as tocopherols. The a-tocopherol molecule is the most potent of the tocopherols. Vitamin E is absorbed from the intestines packaged in chylomicrons. It is delivered to the tissues via chylomicron transport and then to the liver through chylomicron remnant uptake. The liver can export vitamin E in VLDLs. Due to its lipophilic nature, vitamin E accumulates in cellular membranes, fat deposits and other circulating lipoproteins. The major site of vitamin E storage is in adipose tissue.

The major function of vitamin E is to act as a natural antioxidant by scavenging free radicals and molecular oxygen. In particular vitamin E is important for preventing peroxidation of polyunsaturated membrane fatty acids. The vitamins E and C are interrelated in their antioxidant capabilities. Active a-tocopherol can be regenerated by interaction with vitamin C following scavenge of a peroxy free radical. Alternatively, a-tocopherol can scavenge two peroxy free radicals and then be conjugated to glucuronate for excretion in the bile.

One of the most potent antioxidants available, Vitamin E; retards cellular aging due to oxidation; supplies oxygen to the blood which is then carried to the heart and other organs; thus alleviating fatigue; aids in bringing nourishment to cells; strengthens the capillary walls and prevents the red blood cells from destructive poisons; prevents dissolves blood clots; has also been used by doctors in helping prevent sterility, calcium deposits in blood walls, heart conditions, and muscular dystrophy,

Of the several types of Vitamin E, D-Alpha Tocopherol (100% Natural) is 4 times more potent in biological activity than dl-Alpha Tocopherol (Synthetic) Vitamin E. For example; 100 I.U. of d- Alpha (100% Natural) Vitamin E is equal to 400 I.U. d1- Alpha Tocopherol (Synthetic) Vitamin E in biological activity. Natural Vitamin E is derived from soybeans while synthetic Vitamin E is a petroleum by-product.
