The main objective of supplementation with vitamin E is the neutralization of destructive free radicals. Vitamin E occurs in four forms, of which the most important is alpha tocopherol and gamma tocopherol. The alpha tocopherol prevents fat "bad" LDL cholesterol to oxidize and create free radicals. However, scientific studies have shown that vitamin E in the form of gamma tocopherol is vital for human health, since traps and neutralizes existing free radicals. 

Most vitamin E supplements marketed contain only alpha tocopherol. However, gamma tocopherol is one that fights peroxynitrite, ie free radicals responsible for aging. 

In addition, Life Extension has discovered through research that the addition of sesame seeds to gamma tocopherol significantly enhances antioxidant activity. Thus, this supplement enriched with sesame seeds to maximize the antioxidant benefits of gamma tocopherol.
