Rennie is a fast-acting, effective remedy for heartburn and indigestion. When heartburn hits, Rennie quickly gets to work to relieve painful symptoms.
Rennie works directly on the cause of the problem - the acid in your stomach – helping to prevent acid reflux from happening. Rennie acts physically, rather than by entering the bloodstream.
Rennie’s antacid-based calcium carbonate and magnesium carbonate formula works fast, neutralising excess stomach acid, turning it into water and other natural substances. Rennie can be taken day or night to relieve heartburn and indigestion fast.
