Each 700mg beef softgel capsule contains the highest concentration of the complete Vitamin E tocopherol complex — HIGH-Gamma, HIGH-Alpha, with Beta and Delta isomers — completely void of fillers or additives that can turn rancid. This all-natural, PURE Vitamin E concentrate consists of the natural form of Vitamin E as obtained through the diet and as used by the body. Vitamin E is a complex of eight molecules that work together synergistically. Taking a Vitamin E supplement with only d-alpha tocopherol instead of the entire mixed tocopherols family of isomers can actually deplete the level of d-gamma tocopherol in the body.
