Vitamin E (Vitamin E (alpha-tocopherol and related tocopherols/tocotrienols)) — Uses, Dosage, Side Effects & Safety

Drug class: Vitamins & Supplements

Overview

Vitamin E is a fat-soluble vitamin and antioxidant that helps protect your cells from damage caused by free radicals. It is essential for immune function, skin health, and normal cellular processes. Vitamin E is naturally found in foods such as nuts, seeds, vegetable oils, and green leafy vegetables. Vitamin E supplements are used to treat or prevent vitamin E deficiency, which is rare but may occur in people with certain medical conditions affecting fat absorption (such as cystic fibrosis or chronic pancreatitis). Some people also use vitamin E for its potential benefits in skin health, eye health, and as an antioxidant, though evidence for these uses varies. Key points: Most people get enough vitamin E from a balanced diet. High doses of vitamin E supplements may increase the risk of bleeding and other side effects, so always use as directed by your healthcare provider.
