VITAMIN D UPDATE: Vitamin D may lower risk of deadly prostate cancer. “Vitamin D does not protect men from getting prostate cancer, but it may lessen their chances of dying of it. In a new study, men with the highest levels of vitamin D in their blood were 57 percent less likely than men with the lowest levels to succumb to prostate cancer. However, no link was found between vitamin D levels and having prostate cancer, the researchers said.”
