Mechanism of Action: Vitamin E is a general term used to refer to a large number of natural or synthetic compounds. Tocopherols, particularly the alpha tocopherols, are the most active and widely distributed. Alpha tocopherols occur naturally in the d optical isomer form which is more active than the dl synthetic racemic form. Vitamin E is a fat-soluble vitamin that inhibits Vitamin A and C oxidation. It protects the polyunsaturated fatty acids in the membrane from the attack of free radicals and the RBCs against haemolysis. It may be given as d- or dl-alpha tocopherol or as the respective acetates or acid succinates.
Absorption: Absorption from the gastrointestinal tract depends on the presence of bile and normal pancreatic function.
Distribution: Widely distributed into all body tissues; stored in adipose tissue. Crosses the placenta and enters the breast milk.
Metabolism: Metabolised in the liver into glucuronides of tocopheronic acid and its γ-lactone.
Excretion: Mainly via bile; remainder via urine.
