Tocotrienol: High Performance ‘Super Vitamin E’

Vitamin E is an essential nutrient, that protects cells from oxidative stress, and which cannot be made by the body. Oxidative stress results from the overproduction of free radicals, which cause oxidative damage to cells, and con-tributes to the development of chronic dis-ease. The term vitamin E refers to a family of eight closely related compounds: four tocotrienols (alpha-, beta-, delta-, and gamma-tocotrienol) and four tocopherols (alpha-, beta-, delta-, and gamma-tocopherol). Figure 1 shows the molecular structures for tocotrienol and tocopherol, which are quite similar in that they both consist of a chromanol ring and a phytyl side chain. The
