Selenium and Vitamin E Supplements Can Increase Prostate Cancer Risk.
A multi-center study from the Fred Hutchinson Cancer Center in Seattle and published in the Journal of the National Cancer Institute have shown that vitamin E can heighten the risk in men with low baseline selenium levels. In addition, selenium supplements can raise the prostate cancer risk in men with high baseline levels of the trace element. The researchers concluded that their study showed no benefits to any man from either selenium or vitamin E supplements and for a significant number of men, these supplements were actually harmful.
