Vitamin E, also called tocopherol or alpha-tocopherol, is a fat-soluble vitamin that is an important antioxidant. Antioxidants help protect the body from the effects of free radicals which result from normal metabolism.

The U.S. Dietary Reference Intake (DRI) for adults for vitamin E is 15 mg/day. The best source is vegetable oil. Nuts, seeds, and wheat germ also are good sources. Green leafy vegetables provide smaller amounts, and fortified breakfast cereals are also sources of vitamin E.

You can usually obtain enough from foods, but if you eat a low-fat diet, you may not. Taking a multivitamin supplement is a safe way to ensure an adequate intake. Using high-dose vitamin E supplements is not recommended. Check with your health care provider if you are considering taking vitamin E over the DRI level. Also, you should let your health care provider know about any over-the-counter medications, vitamins, and minerals you take.
