Rennie Peppermint tablets contain two naturally-occurring antacids called calcium carbonate and magnesium carbonate which neutralize the excess stomach acid by turning it into the water & other natural substances. Calcium carbonate acts directly in the esophagus, as well as the stomach, and both antacids are then eliminated by your body.
