Molecular Structure



Vitamin E exists in eight different forms (alpha-, beta-, gamma-, and delta-tocopherols and tocotrienols) each of which has slightly different activity in the body. Even though there are 8 forms of Vitamin E, the most biologically active form of the vitamin is called alpha-tocopherol. Alpha-tocopherol is considered the active form because it is the preferred form of vitamin E transported and used by the liver.

Natural Vitamin E is generally labeled d-alpha tocopherol, d-alpha tocopheryl acetate, or d-alpha tocopheryl succinate but can sometimes appear as mixed tocopherols (mixed tocopherols, the most desirable of vitamin E forms, contain not only d-alpha tocopherol but natural mixtures of beta, gamma, and delta tocopherols).

Due to its molecular structure, natural vitamin E is much better absorbed in the body. Specific transport proteins in the liver tend to bind better to natural vitamin E, allowing it to be transported to other tissues in the body to be used for important functions, including as an anti-oxidant.

Because of its ability to quench free radicals, Vitamin E is consider a protector and healer for the body. Vitamin E is an anti-oxidant, and an excellent moisturizing and rejuvenating ingredient. Studies have shown that Vitamin E reduces UV-induced erythema, edema, sunburn cell formation, and lipid peroxidation. Clinical improvements in the visible signs of skin aging (skin wrinkling) have been documented as well.
