Supplements Don't Prevent Prostate Cancer: University Health Network Study

A new study deflates hopes that certain nutritional supplements could stave off prostate cancer, the second most common cancer in men. Canadian researchers found that vitamin E, selenium and soy, taken daily for three years, provided no benefit to men who were at a higher risk of developing the disease. The findings come three years after a larger study of men, who were at no increased risk of prostate cancer, also found no benefit of selenium or vitamin E supplementation (see Reuters Health report, October 28, 2008).
