Recent research has demonstrated that gamma-tocopherol, the main dietary source of vitamin E, has a very important role in supporting health. Gamma-tocopherol is a more effective antioxidant than alpha-tocopherol and may be an important factor for a healthy cardiovascular system. It also inhibits the COX-2 enzyme, according to in vitro tests. Research indicates that a ratio of gamma to alpha-tocopherol greater than 1:1 increases levels of both tocopherols in the body and that alpha-tocopherol alone may not be adequate to combat oxidative stress. Source Naturals Gamma-E 400 offers a 3:1 gamma to alpha-tocopherol ratio (200 IU equals 133 mg) and also contains tocotrienols from palm fruit which provides high concentrations of all four tocotrienols: alpha, beta, gamma, and delta. Sesame oil, rich in gamma-tocopherol, is used as the base.

Gamma E 300 contains Gamma Tocopherol, one of the eight members of the vitamin E family found concentrated in plant seeds and vegetable oils. Typical Vitamin E supplements only offer d-alpha tocopherol, which has been shown to deplete serum gamma tocopherol and alpha tocotrienol.
Gamma tocopherol is especially protective against reactive nitrogen species which damage lipids, proteins and DNA.Inside the body, gamma tocopherol is found in high concentrations in the skin, muscle and venous tissue. Each softgel of Gamma E 300 contains more gamma tocopherol than a kilogram of pecans, pistachios, or walnuts.

High Gamma Tocopherol is a concentrated blend of gamma and alpha-tocopherols (plus tocotrienols), which exhibit favorable effects on prostate and cardiovascular health it also possess antioxidant properties.
