D-alpha-tocopherol is a vital nutritional ingredient and recognised as a valuable anti-oxidant in human food stuffs. D-alpha-tocopherol deficiency in humans can lead to serious illnesses. In medicine, D-alpha-tocopherol is used for treating gingivitis, coarse-skin disease, fatty liver (hepatic adipose infiltration), arteriosclerosis and high blood cholesterol levels. D-alpha-tocopherol is also used as a food additive and fortifier, and as animal feed additives, and is known to improve human and animal reproductive function. As a cosmetic additive, D-alpha-tocopherol is known to prevent skin ageing, improve skin elasticity and rejuvenation. D-alpha-tocopherol occurs as a brownish red to light yellow, clear, viscous oil having a mild, characteristic odour and taste. Its biological activity is three times higher than synthetic VE. Unlike its synthetic counterpart, natural VE does not contain any chemical contaminations which result from the chemical synthesis process.
