Vitamin E is a group of fat-soluble compounds, mainly tocopherols and tocotrienols. Alpha-tocopherol is the most active form in humans and acts primarily as an antioxidant.

What are the main benefits of Vitamin E?

Vitamin E helps protect cells from oxidative stress and supports normal immune function. It may also help protect LDL cholesterol from oxidation and is commonly used for skin support, especially in topical products.

What foods are high in Vitamin E?

Common sources include nuts and seeds, vegetable oils, and leafy green vegetables. Because it is fat-soluble, it is typically absorbed better when consumed with dietary fat.

How much Vitamin E should I take?

Many adults aim for about 15 mg per day from diet and/or supplements, while higher supplemental intakes are sometimes used. High doses may not be appropriate for everyone, so consider individual needs and medical guidance.

Is Vitamin E safe, and who should be cautious?

Vitamin E is generally safe at typical dietary intakes, but high-dose supplements can increase the risk of side effects in some people. Those using blood-thinning medications, with bleeding disorders, or preparing for surgery should be cautious and consult a clinician.

Safety & Information

Important safety information & known risks

For educational purposes only • not medical advice

Vitamin E is generally safe at recommended intakes, but high doses increase bleeding risk and may cause other adverse effects in specific groups.

warning notices
