Vitamin E may also help protect against heart disease by reducing the blood's ability to clot and by helping to reduce inflammatory processes. Besides its role in reducing the risk of heart disease, several recent studies have shown that vitamin E can help bolster the immune system, especially among older people. Similar results were seen in a study with rats. Other studies suggest that vitamin E helps prevent or reduce the effects of a wide range of diseases, including certain cancers, arthritis, cataracts, Parkinson's, diabetes and Alzheimer's disease. So far, however, the evidence about these remains inconsistent or preliminary.
Alpha tocopherol is by far the main form in the body, as well as in supplements.
Gamma is the main tocopherol in foods. While more study is needed, this suggests that while people at high risk of heart disease may want to consider taking a daily supplement of vitamin E, it's also wise to eat a variety of foods that includes good sources of vitamin E. Nuts, seeds, whole grains, fortified cereals, vegetable oils, margarine, seafood, liver and leafy green vegetables are all good food sources of vitamin E. Finally, those on blood-thinning medications or high doses of pain relievers should take vitamin E supplements only under their doctor's supervision, since taking supplements while on these medications may be counter indicative.
