This was a really poorly done study as they only gave participants 2,000 IUs a day and never measured their blood levels. The risk was reduced by as much as 38% among those who also maintained a healthy weight. In the first of these studies, 1, 2В which included 25,871 patients, vitamin D supplementation was found to reduce the risk for metastatic cancer and death by 17%.
