Vitamin D Reduces Precancerous Polyps

In the December 2005 edition of the journal Cancer, a study on colon polyps, frequently precursors of colon cancer, was reported. Of the nineteen participants, eleven were given calcium carbonate 1500 mg, plus vitamin D3 400 IUs, three times daily, whereas the rest were given placebo for six months. It was found calcium plus vitamin D resulted in tissue changes that may have contributed to reduce polyp formation.
