    Vitamin E is key for strong immunity and healthy skin and eyes. In recent years, vitamin E supplements have become popular as antioxidants. These are substances that protect cells from damage. However, the risks and benefits of taking vitamin E supplements are still unclear.

    Why do people take vitamin E?

    Many people use vitamin E supplements in the hopes that the vitamin's antioxidant properties will prevent or treat disease. But studies of vitamin E for preventing cancer, heart disease, diabetes, Alzheimer's disease, cataracts, and many other conditions have been inconclusive.

    So far, the only established benefits of vitamin E supplements are in people who have an actual deficiency. Vitamin E deficiencies are rare. They're more likely in people who have diseases, such as digestive problems and cystic fibrosis. People on very low-fat diets may also have low levels of vitamin E.

    How much vitamin E should you take?

    The recommended dietary allowance (RDA) includes the vitamin E you get from both the food you eat and any supplements you take.

    The tolerable upper intake levels of a supplement are the highest amount that most people can take safely. Higher doses might be used to treat vitamin E deficiencies. But you should never take more unless a doctor says so.
