A government study has determined that vitamin E and selenium are ineffective in preventing prostate cancer and may pose health risks to users. The study, known as the SELECT trial, was halted due to these findings.
According to the Associated Press, early data from the trial indicated that neither supplement, taken alone or together, proved effective in preventing prostate cancer. Additionally, the National Cancer Institute reported slight increases in prostate cancer among vitamin E-only users and higher diabetes incidence among selenium-only users.
