A distance athlete explains why he is taking a vitamin E supplement. He states: "Most people don't realize it but oxygen has both beneficial and harmful effects. I try to counter the harmful effects by taking a vitamin E supplement. Most studies have shown that vitamin E supplementation has a positive effect on endurance performance. Besides, recent studies have shown that there is a health
benefit to vitamin E supplements. I'm concerned that my vitamin E intake may be low since I purposefully keep my calorie intake low so I don't gain any body fat and I follow a low-fat diet. Someone told me that when you take high levels of vitamin E it actually has an opposite effect and it is no longer works as an antioxidant, but I don't think that is true.". High levels can actually have an opposite effect and the vitamin E no longer works as an antioxidant.
