Long-term use of vitamin E is more prone to prostate cancer

Researchers recently released by US researchers show that the daily use of vitamin E supplements significantly increases the risk of prostate cancer.

In this clinical trial of 35,000 middle-aged men, the patients were all over the age of 50. Researchers at the Cleveland Clinic in the United States divided them into 4 groups: selenium group (200 mg/day); vitamin E group (400 IU/day); selenium and vitamin E (group; placebo group. The number of people is around 8700. Researchers have a minimum tracking time of 7 years and a maximum of 12 years.

The results showed that 76 people in the vitamin E group had prostate cancer per 1,000 people compared with 65 in the placebo group. In proportion, the incidence of prostate cancer in the vitamin E group was 17% higher than that in the placebo group.

“The public and consumers take it for granted that vitamins are harmless and that taking vitamins will not have any negative consequences,” said Eric Klein, who led the study. “Obviously, this is not the case.”

The National Institutes of Health (NIH) also released a research report earlier that blindly taking dietary supplements to supplement minerals may harm the body's health.
