(Ivanhoe Newswire) High doses of Vitamin D wont help reduce a mans risk of prostate cancer.
According to a new study conducted by researchers from the National Cancer Institute, men with more vitamin D in their blood are just as likely to develop the disease as men with less. In fact, men with a higher concentration of vitamin D in their blood are at a greater risk for the most aggressive form of the disease. While the finding wasnt considered statistically significant, the investigators believe it might raise a red flag.

Fellow researchers writing in an accompanying editorial agree. They believe its important to study the vitamins effect on aggressive cases of prostate cancer. However, they also emphasize more study is needed because other studies have not shown such a link.
Men in the study were taking part in a larger clinical trial on cancer. The investigation compared the vitamin D levels of 749 men diagnosed with prostate cancer with that of 781 men without cancer.
