Now Advanced Gamma E Complex is a full-spectrum vitamin E supplement that features gamma-tocopherol and includes a natural balance of tocopherols and tocotrienols. Gamma-tocopherol, the most abundant form of vitamin E in the diet, is especially important due to its unique ability to detoxify and eliminate reactive nitrogen species, a particularly destructive form of free radical. The vitamin E family of tocopherols and tocotrienols is well known for its role in the maintenance of cardiovascular health and normal immune system function.
