Calcium citrate doesn't normally cause constipation like calcium carbonate does. Chances are your supplement has citrate and carbonate even though the front will just say citrate. You should look at the label (on the back) and see if it contains carbonate as well. Citracal is a good one that is total citrate. If you still have problems, you can look for calcium phosphate which is not supposed to constipate you either. I hope you find success with these. Have you asked your doctor for suggestions?
