Hello. I have IBS-A and I was looking for some medicines that could help me during my diarrhea attacks other than Lomotil and Immodium and I've encountered some people on IBS forums who say that calcium carbonate helped them. Then I bought a pill of calcium tablets but in its prescription it says Each whitish, effervescent tablet contains: calcium lactate-gluconate 2 940 mg, calcium carbonate 300 mg and provides 500 mg (12.5 mmol) elemental calcium. But people here seem to use calcium carbonate only I suppose. What is calcium lactate gluconate? Does it matter if i take this instead of calcium carbonate?
