Rennie Spearmint - 24 Tablets

Rennie Spearmint 24 Tablets are fast-acting chewable antacid tablets formulated to provide effective relief from symptoms of excess stomach acid including heartburn, indigestion, acid reflux and dyspepsia. Each tablet contains a dual-antacid combination of calcium carbonate and magnesium carbonate, which work together to neutralise excess gastric acid directly at the source, turning it into water and other natural substances.
