What should I know before using vitamin E supplements?

Overconsumption of the synthetic form of vitamin E that is found in supplements and/or fortified foods could pose risks.

Because vitamin E can act as an anticoagulant and interfere with blood clotting, excess amounts in your body increase the risk of hemorrhage. Because of this, the upper level from supplements and/or fortified foods is 1,000 milligrams for adults. This applies only to healthy individuals consuming adequate amounts of vitamin K. (Vitamin K also plays a role in blood clotting. A deficiency of vitamin K can exacerbate the anticoagulant effects of vitamin E.)

Individuals taking anticoagulant medication and vitamin E supplements should be monitored by their physician to avoid the serious situation in which the blood can’t clot quickly enough to stop the bleeding from a wound.

Always consult with your health care provider and a registered dietitian before taking a vitamin supplement. To find a registered dietitian in your area, please visit: www.eatright.org.
