The trace mineral selenium protects the prostate from the accumulation of DNA damage which may reduce your risk of prostate cancer. With SeleniumHealth™, you can measure and adjust your selenium intake to reduce your prostate cancer risk while avoiding the adverse consequences of oversupplementation.
"When we studied the relationship between selenium intake and how much DNA damage accumulated in the prostate, we discovered that the amount of DNA damage is most severe at the lowest and highest selenium intake. Clearly, more is not always better!"
