Colorectal Cancer, Adenocarcinoma of the Colon, Rectal Cancer, Colon Cancer, and Colon Polyps

Calcium dose and recurrence of colon adenomas: In a meta-analysis by Carroll C., et al, 3 trials showed a reduction of recurrence of colon adenomas for subjects who took 1200 – 2000 mg per day of a calcium supplement, but no decrease in risk for those with advanced adenomas. Also as part of the meta-analysis, 2 trials were found by the author which showed no benefit of calcium in those without increased risk of colorectal cancer. (2)

Palacios C et al found that subjects with a median of 1180 mg per day of calcium whether from dietary calcium intake or calcium from supplements as opposed to a median of 1036 mg per day had less colorectal neoplasia. (29)
