Vitamin D Found to Lower Colon Cancer Risk
New data from five studies has found that Vitamin D may reduce the risk of colon cancer. The beneficial amount appears to be 1,000-2,000 IU per day.
Dr. Edward D. Gorham, from the Naval Health Research Center in San Diego, California, and colleagues found that as blood levels of vitamin D rose, the risk of colorectal cancer fell. Risk was reduced by 54 percent in groups with the highest vitamin D levels relative to those with the lowest levels.
