Mark Hyman, MD talks about the truth regarding some studies that show vitamins can kill people. It seems that the information is misleading people as to whether or not to stop taking their vitamins. Vitamins and supplements offer so many health benefits to people, and yet some studies prove otherwise. Just like the study that showed Vitamin E and Selenium can increase the risk of prostate cancer rather than prevent it. While this may be true, it also has to be taken into consideration that the combination of these two vitamins is just not the perfect one for prostate cancer.
