Calcium carbonate is the type of calcium that is suggested to help with diarrhea. Calcium citrate should not cause you constipation issues like the carbonate form. The citrate is from citrus sources and as long as you can tolerate that than it should be fine. I would just verify it with your doctor but you shouldn't have the constipation issues.
