Researchers believe that when men take too much vitamin E with selenium, men have a higher risk of getting prostate cancer.
The study was conducted on 1700 men with prostate cancer and 3100 healthy men in 2001. The men were randomly assigned to receive high doses of vitamin E and selenium, or take on placebo body.
Before participating, the researchers measured the amount of selenium in the toenails of the participants.
The results showed that people who took vitamin E had more prostate cancer than men who took placebo. At the same time, vitamin E also doubles the risk of prostate cancer in people with low selenium levels.
Dr. Eric Klein - Dean of the urology and kidney department of Cleveland Hospital and his colleagues, told the National Cancer Institute magazine: 'Men should avoid taking selenium and vitamin E supplements beyond the dosage'. .
These findings suggest a complex interaction between selenium and vitamin E. At the same time, research shows that vitamin E increases the risk of cancer in men with low selenium levels.
This is a surprise because earlier, Paul Frankel - a biological statistician of the Mixed Cancer Center said that vitamin E and selenium have an antioxidant role and that vitamin E supplementation can compensate. The antioxidant deficit due to low selenium concentration.
Klein added: 'Vitamins are not non-toxic. They can be harmful to you. '
Researchers recommend that men older than 55 should avoid taking large amounts of vitamin E or selenium in their diets.
