Vitamin E and Exercise
Many athletes consume vitamin and mineral supplements thinking that they offer some magic power. If only it were that easy. Hard work, a balanced diet of real food, and patience are what counts toward success on the court and field. Unless you are deficient in certain vitamins or minerals, there is no evidence that supplementation will help your athletic performance. 
Things to keep in mind: 
- Vitamins do not provide energy directly. They regulate protein, carbohydrates and fat metabolism, which are the real sources of energy.
- If you progress in your performance with the use of vitamin supplements, it may be that you had been deficient in them before, or you're experiencing a placebo effect.
- If you're concerned about your diet, seek advice from a registered dietician who works with athletes.
- Antioxidant supplementation, vitamin E included, may provide a side benefit to performance by helping to strengthen skeletal muscle and the immune system, but more research is needed.
What Medications May Adversely Interact With Vitamin E?
If you are taking any of the following medications, consult your health care provider before taking vitamin E.
- AZT (HIV/AIDS)
- Bile acid sequestrants (cholesterol)
- Chemotherapy drugs
- Calcium channel blockers
