Vitamin E

Generic descriptor for all tocopherols and tocotrienols that exhibit alpha-tocopherol activity

Vitamin E is a group of eight fat soluble compounds that include four tocopherols and four tocotrienols. Vitamin E deficiency, which is rare and is usually caused by an underlying problem with digesting dietary fat rather than from a diet low in vitamin E, can cause nerve problems. Vitamin E is a fat-soluble antioxidant which may help protect cell membranes from reactive oxygen species. Governmental organizations worldwide recommend that adults consume between 3 and 15 mg per day. As of 2016, consumption was below recommendations, according to a worldwide summary of more than one hundred studies that reported a median dietary intake of 6.2 mg per day for alpha-tocopherol. Foods rich in vitamin E include seeds and nuts, seed oils, peanut butter, and vitamin E-fortified foods.
