Colorectal Polyps

Colorectal polyps are small growths on the inner lining of the colon or rectum, and while most are harmless, some types called adenomas can slowly turn into colorectal cancer over time. Calcium and vitamin D have the most support as supplements people look at for polyps, with the evidence rated moderate for each, though little trial research on them has been reviewed here so far. Fiber and omega-3s also have moderate evidence, while the rest, such as folate, probiotics and green tea extract, rest on limited data.
