Vitamin E (Alpha Tocopherol), Serum


Vitamin E is a fat soluble vitamin which is absorbed by the small intestine (enterocytes) after solubilisation in bile salt micelles. Vitamin E is found in two forms γ- tocopherol (from diet) and α- tocopherol (from supplements). Nuts and seeds are particularly rich in vitamin E. The protective action of vitamin E against atherosclerosis is most likely related to its preventive action against lipid peroxidation. The ability of vitamin E to induce apoptosis in tumour cells and modulate oncogenes may be essential for its anticarcinogenic effect. Vitamin E deficiency may be associated with platelet hyperaggregation, ceroid deposition in smooth muscles, decreased red blood cell survival and susceptibility to haemolysis.


Vitamin E level is increased in cases of hyperlipidaemia of obstructive liver disease. Decreased levels are associated with malabsorption, premature infants and abetalipoprotienaemia.
