Alpha-tocopherol is traditionally recognized as the most active form of vitamin E in humans, and is a powerful biological antioxidant. The measurement of "vitamin E" activity in international units (IU) was based on fertility enhancement by the prevention of spontaneous abortions in pregnant rats relative to alpha tocopherol. It increases naturally to about 150% of normal in the maternal circulation during human pregnancies. 1 IU of vitamin E is defined as the biological equivalent of 0.667 milligrams of RRR-alpha-tocopherol (formerly named d-alpha-tocopherol, or of 1 milligram of all-rac-alpha-tocopheryl acetate (commercially called dl-alpha-tocopheryl acetate, the original d,l- synthetic molecular mix, properly named 2-ambo-alpha-tocopherol, is no longer manufactured). The other R,R,R tocopherol vitamers are slowly being recognized as research begins to elucidate their additional roles in the human body. Many naturopathic and orthomolecular medicine advocates suggest that vitamin E supplements contain at least 20% by weight of the other natural vitamin E isomers. Commercially available blends of natural vitamin E include "mixed tocopherols" and "high gamma tocopherol" formulas. Also selenium, Coenzyme Q10, and ample vitamin C have been shown to be needed for effective antioxidant recycling of tocopherols.
The overall wisdom of synthetic and semisynthetic vitamin E supplementation has been increasingly questioned in recent years. A controversial[10] 2005 meta analysis of vitamin E esters supplementation questioned the benefit of high dosage alpha tocopheryl esters.[19] This meta analysis found that "high dose" vitamin E esters(>400 units/day) were associated with an all cause mortality risk difference of 39 per 10,000 persons, including some trials using synthetic beta-carotene and other cofounders to supply the mortality. Further, the Miller group claimed a significant relationship between dose and all-cause mortality, with increased risk with doses exceed 150 units per day.

Vitamin E is one of my fawvorite vitamins. It is good for skin. Whenever I cut myself, have chaped lips, have dry skin, etc, I use some vitamin e oil, and it helps a lot! One can also get vitamin e suppliments (pill form) which is a good way to keep your skin and hair looking healthy.
