Vitamin D and Colon Cancer Risk

There’s been much study on the role of vitamin D in reducing the risk of colorectal cancer. Recent research pooled date on 5,700 patients with colorectal cancer and 7,100 without the disease. Researchers found that those whose vitamin D blood levels were between 30 and 34.9 ng/mL had a 19% lower risk of the cancer over the six-year study period than those whose levels were between 20 and 24.9 ng/mL. Participants with levels between 35 and 39.9 had a 27% lower risk. The study only proves association, not cause-and-effect. Check with your doctor to make sure you’re getting enough vitamin D.
