I am taking Vitamin D (thanks to your info) and my Mylanta has 400mg of Calcium Carbonate in it. MG??? I think it said mg.

My Gastro...sorry ... brain fade .... the doctor who manages my GERD suggested Mylanta a couple of years ago. I go through a 12oz bottle in 3-4 days. GERD causes really bad things to happen to me, so I take Nexium (Max Dose) and use Mylanta. If you have ever had an attack of Vocal Cord Dysfunction, you would know why I am real careful not to let my GERD get too active.

Thanks again, I will switch to Calcium Citrate tomorrow. I guess Walmart has it??
