Vitamin E is a fat-soluble antioxidant in many foods. It supports the immune system, helps keep blood vessels healthy, and plays a role in gene expression and cell signaling. There are eight forms of naturally occurring vitamin E, and it is alpha-tocopherol that the body mainly uses.

Vitamin E acts as an antioxidant and helps protect the body from free radicals. Free radicals can cause disease in the body and contribute to the aging process. In addition, vitamin E is important for immune function, gene expression and cell signaling. It helps to dilate blood vessels and prevent excessive clotting.
But results on many uses of vitamin E, including helping to prevent cognitive decline, are conflicting or inconclusive. Despite this, the National Institutes of Health acknowledges that vitamin E may be beneficial for people with certain conditions.
For example, several studies suggest that vitamin E helps prevent or delay coronary heart disease. Some research shows that vitamin E inhibits the formation of cholesterol, thus helping to prevent blood clots. The National Institutes of Health shows evidence that taking vitamin E along with zinc, copper, and other antioxidants can slow disease progression in people at high risk of the advanced form. However, the evidence supporting the use of vitamin E to treat or prevent eye disorders is considered inconsistent. Researchers are investigating the antioxidant and immunomodulatory effects of vitamin E on cancer.
The National Institutes of Health warns of health risks to vitamin E supplements. Taking high-dose vitamin E supplements may increase the risk of cerebral hemorrhage and stroke from prostate cancer.
Vitamin E is found in many foods. A few foods rich in vitamin E include: seeds such as sunflower or pumpkin seeds, vegetable oils such as wheat germ, sunflower or safflower oil, hazelnuts including almonds, hazelnuts and walnuts, green vegetables such as nut butter, spinach, kale and broccoli, avocado, mango , red bell pepper, and many fortified foods, such as cereals, juices, and margarine.
