Vitamin E Succinate (natural), 400 IU, 100 capsule
Vitamin E Succinate (natural)400 IU, 100 capsules Item Catalog Number: 063The term 'vitamin E' refers to a family of eight related, lipid-soluble, antioxidant compounds widely distributed in plants. The tocopherol and tocotrienol subfamilies are each composed of alpha, beta, gamma, and delta vitamers having unique biological effects. Different ratios of these compounds are found in anatomically different parts of a plant. For example, the green parts of a plant contain mostly alpha-tocopherol and the seed germ and bran contain mostly tocotrienols.When this family of compounds was first discovered and determined to be essential for health, a standardized test for its activity was devised for which the members of the family were rated for their biological activity. In one test, alpha tocopherol scored highest and was rated 100% with all others having lower ratings. In accordance with this rating, alpha-tocopherol was deemed to be the essential compound and was called vitamin E. One International Unit (IU) of vitamin E activity is the activity under this rating of 1 mg of the plant-derived form of alpha- tocopherol.Since the original rating method was established, many additional important biological effects of these compounds have been discovered and many nutritional scientists now consider that rating method to be incomplete. For example, by the original rating, gamma-tocopherol was only 10% to 30% as strong as alpha-tocopherol, yet recent studies have shown it to be essential for maintaining the health of cell membranes, especially if alpha-tocopherol is being supplemented. New studies continue to elucidate the unique benefits of individual members of the vitamin E family. For these and other reasons, the original definition of vitamin E has been enhanced to include all eight family members and the related compounds that convert to them in the body. Vitamin E compounds are usually produced and made available in esterified form as alpha-tocopheryl acetate or
