Vitamin E Acetate

Vitamin E describes a family of eight antioxidants:

four tocopherols (alpha-, beta-, gamma-, and delta-)
four tocotrienols (alpha-, beta-, gamma-, and delta-)

Alpha-tocopherol is the only form of vitamin E that is actively maintained in the human body and therefore the form of vitamin E found in the largest quantities in blood and tissues.

Vitamin E Acetate is a synthetic form of Vitamin E.

The main function of Vitamin E is that of an antioxidant. Free radicals are formed primarily in the body during normal metabolism and also upon exposure to environmental factors, such as cigarette smoke or pollutants. Fats, which are an integral part of all cell membranes, are vulnerable to destruction through oxidation by free radicals. Being a fat-soluble vitamin, Vitamin E is uniquely suited to intercept free radicals and thus prevent a chain reaction of lipid destruction.

Aside from maintaining the integrity of cell membranes throughout the body, Vitamin E also protects the fats in low density lipoproteins (LDLs) from oxidation. Lipoproteins are particles composed of lipids and proteins that transport fats through the bloodstream. LDLs specifically transport cholesterol from the liver to the tissues of the body. Oxidized LDLs have been implicated in the development of cardiovascular diseases.

Several other functions have been identified that are not likely related to its antioxidant capacity. For instance, alpha-tocopherol is known to inhibit the activity of protein kinase C, an important cell-signaling molecule. Alpha-tocopherol appears to also affect the expression and activities of molecules and enzymes in immune and inflammatory cells. Additionally, alpha-tocopherol has been shown to inhibit platelet aggregation and to enhance vasodilation.

The isomeric form of alpha-tocopherol found in foods is RRR-alpha-tocopherol (also referred to as "natural" or d-alpha-tocopherol). Synthetic alpha-tocopherol, which is labeled all-rac- or dl-alpha-tocopherol, has only one-half the biological activity of RRR-alpha-tocopherol. Often vitamin E-fortified foods contain synthetic alpha tocopherol, and the amounts are given as a percentage of the daily value of 30 IU.

The bioavailability of alpha-tocopherol from alpha-tocopheryl acetate is equivalent to that of free alpha-tocopherol.
