What are the risks of taking vitamin E?

Dr. Michael Roizen, MD
Internal Medicine
Like aspirin, vitamin E thins your blood, making clots less likely to form. The quinone (a chemical part of vitamin E) in vitamin E has powerful anticlotting powers. Several studies have noticed an increase in bleeding when vitamin E and aspirin are used in combination, a condition implicated in both ulcers and strokes. It is rare, but discuss this possibility with your physician, especially if you have a history of ulcers or other blood-clotting problems.

Vitamin E is safe when taken for short periods of time and with the recommended dose. Taking vitamin E for a prolonged period of time and in high doses may increase the risk of death by a small amount. In some rare cases, vitamin E supplements have caused gonadal dysfunction and reduced kidney functioning. Taking high doses of vitamin E may also increase the risk of bleeding.
