Rennie Liquid Heartburn Relief MINT Flavour uses a combination of two antacids and an alginate. The antacids are calcium carbonate and sodium bicarbonate. They work in two ways to relieve symptoms. First, they lower the effect of excess stomach acid. This reduces pain and discomfort from heartburn. Second, they form a protective barrier on top of the stomach food. This barrier stops stomach acid from escaping into the oesophagus.

Gastroesophageal reflux is when stomach food returns back up into the esophagus. It causes acid regurgitation, heartburn, and indigestion. These symptoms often happen after eating meals or during pregnancy.

Rennie is formulated for quick relief of these symptoms. It forms a protective barrier around the stomach. This barrier aims to prevent symptoms from getting worse. Or even prevent symptoms from happening in the first place.
