Do vitamin E supplements increase the risk of cancer?

Dr. Mehmet Oz, MD

Vitamin E is an antioxidant that's been touted to prevent lung cancer. However, in excess amounts, vitamin E can actually become an anti-anti-oxidant and damage DNA, which can lead to cancer growth.

(Until recently, vitamin E was recommended to ease hot flashes, but new evidence suggests that long-term use may actually be harmful.)

The Food and Drug Administration (FDA) recommended daily value for vitamin E is 30 IU, which means you really don't need to take a vitamin E supplement in addition to your multivitamin. The optimal way to get vitamin E is in your diet. Pistachios are one of the best dietary sources of gamma-tocopherol, a form of vitamin E. One or two handfuls of these nuts a day provides a healthy dose of this nutrient.
