@nycmusic Trying/switching to a plant-based calcium couldn’t hurt at all.

IBS-C however, is a delicate condition that only your gastroenterologist could advise you about.

In the immediate present, good, ‘ol prune juice with a hot coffee or tea chaser can get the job done, provided it doesn’t cause you cramping or discomfort. My gastroenterologist recommends Smooth Move tea (I haven’t tried; I do well with the occasional prune juice and coffee), but again, with IBS-C, if you can’t get in to see your doc right away, ask the nurse what’s safest and most effective for you. They should be able to help until you can get an appointment.
