Vitamin E is the primary fat soluble antioxidant. It supports red blood cell integrity, supports immune function and plays a role in supporting healthy fertility. Research has shown that the health benefits associated with Vitamin E come from a family of compounds known as tocopherols, of which there are four; Alpha, Beta, Gamma, and Delta. Only one of these compounds, alpha tocopherol, has been officially recognized as Vitamin E.
However, the other tocopherols, especially gamma tocopherol, have shown strong biological benefits, as well. Since total Vitamin E activity is not associated exclusively from the level of the one single tocopherol compound, having a nutritional formulation that supplies the full spectrum of tocopherols offers a valuable addition to your nutritional program.
Gamma tocopherol is a major part of the Vitamin E family and also has antioxidant functions. Gamma tocopherol supports healthy immune function, normal cell integrity and reduces excessive oxidative stress.
You will notice some formulas have Vitamin E measured and guaranteed in milligrams (mg), rather than International Units (IU). That is by design. When using a blend of the mixed tocopherols, the correct measurement is by weight of all mixed tocopherols, not by international unit, which is a measurement of only the D-Alpha tocopherol specifically.
