Are selenium supplements recommended for prostate cancer prevention?
['Our meta-analysis in prospective studies demonstrated a significant inverse association between selenium status and CVD risk within a narrow selenium range and a null effect of selenium supplementation on CVD was observed in RCTs. These findings indicate the importance of considering selenium status, dose and safety in health assessment and future study design.', 'Selenium supplementation of 140 or more μg/day after diagnosis of nonmetastatic prostate cancer may increase risk of prostate cancer mortality. Caution is warranted regarding usage of such supplements among men with prostate cancer.', 'The SELECT study failed to show any significant risk reduction for prostate cancers ascribable to selenium and vitamin E supplementations.', 'Vitamins and supplements, including selenium or vitamin E, have not been proven in clinical trials to prevent prostate cancer and in the case of Vitamin E has been found to increase the risk of incident prostate cancer. Ongoing and future trials may further elucidate the role of diet and immunotherapy for prevention of prostate cancer.']
