Containing antacid to neutralise excess stomach acid, Rennie Spearmint tablets work fast to relieve the symptoms of heartburn and indigestion.

Rennie® Spearmint tablets contain two antacids called calcium carbonate and magnesium carbonate which neutralise excess stomach acid by turning it into water & other natural substances. Calcium carbonate acts directly in the oesophagus, as well as the stomach, and both antacids are then eliminated by your body.
