<<Disclaimer: Verify this information before applying it to your situation.>> Someone just wrote in saying that Tums are not gf. Does anyone know for sure? I've been taking Tums for 2 years now and have never had a problem. I need to take it for Calcium and can't have take anything else. If it is not gf, just what ingredient is in it that makes it so. I can't see anything in the ingredients that contains gluten. Simone, NH
