Vitamin E is found naturally in some foods, added to others, and available as a dietary supplement. Serum concentrations of vitamin E (alpha-tocopherol) depend on the liver, which takes up the nutrient after the various forms are absorbed from the small intestine.
Signs of vitamin E deficiency include neuromuscular problems such as spinocerebellar ataxia and myopathies. Other neurological signs may include dysarthria, absence of deep tendon reflexes, loss of vibratory sensation and proprioception, and positive Babinski sign. Deficiency can also cause anemia due to oxidative damage to red blood cells, retinopathy and impairment of the immune response. There is also some laboratory evidence that vitamin E deficiency can cause male infertility.
Many claims have been made about vitamin E's potential to promote health and prevent and treat disease. Vitamin E plays a significant role as an antioxidant like vitamin C. It protects cells from the damaging effects of free radicals, which are molecules that contain an unshared electron. Free radicals damage cells and might contribute to the development of cardiovascular disease and cancer. In addition to its activities as an antioxidant, vitamin E is involved in immune function and, as shown primarily by in vitro studies of cells, cell signaling, regulation of gene expression, and other metabolic processes. Alpha-tocopherol inhibits the activity of protein kinase C, an enzyme involved in cell proliferation and differentiation in smooth muscle cells, platelets, and monocytes. Vitamin-E–replete endothelial cells lining the interior surface of blood vessels are better able to resist blood-cell components adhering to this surface. Vitamin E also increases the expression of two enzymes that suppress arachidonic acid metabolism, thereby increasing the release of prostacyclin from the endothelium, which, in turn, dilates blood vessels and inhibits platelet aggregation. Many women also use it to help minimize the appearance of wrinkles, and mothers use it to help heal minor wounds without scarring, as it is valued for its ability to soothe and heal broken or stressed skin tissue.
