Despite promise, vitamin D and calcium do not reduce colorectal cancer risk

(University of Colorado Anschutz Medical Campus) The New England Journal of Medicine reports results of a 2,259-person study conducted at 11 academic medical centers showing that dietary supplementation with vitamin D and/or calcium after removal of pre-cancerous colorectal adenomas (aka polyps) does not reduce risk of developing future adenomas. Despite promising findings in models of the disease and in previous, smaller trials, the study offers strong evidence against the usefulness of these supplements in the prevention of future polyps.
