Antioxidants such as vitamin E act to protect cells against the effects of free radicals, which are potentially damaging by-products of energy metabolism. Free radicals can damage cells and may contribute to the development of cardiovascular disease and cancer.Since many years now studies have been going on to determine whether Vitamin E can be used to cure heart diseases. Vitamin E in Heart Disease – Previous findings Studies on animals were conducted and it was proved that vitamin E could help protect patients who are at risk for suffering a heart attack. An observational study in Finland involving over 5000 people suggested that Vitamin E supplements was associated with lower death rate from heart disease. However, clinical studies conducted on humans had not been able to produce similar results. Vitamin E in Heart Disease – New findings In a new study scientists found out that much larger dose of the vitamin is required to be given to humans to produce some effect. Consequently larger doses were administered but it did not have a major effect on oxidative stress. It is also doubtful whether taking doses is safe in the long term or not. Although animal studies have suggested that vitamin E does slow the development of atherosclerosis, but the American Heart Association doesn’t recommend using supplements until the effects are proven in large-scale, carefully controlled clinical trials.
