THE RENNIE RANGE

With over 85 years of experience, a great taste and easy availability, it’s no surprise that Rennie is the UK's No.1 Heartburn & Indigestion tablet*. We have a range of antacids each developed to bring you quick, lasting relief from your symptoms, so you can get on with your life.

Rennie is an antacid which neutralises excess stomach acid simply by turning it in to water and other natural substances, rather than masking it. Rennie acts directly on the cause of the problem, which is the acid in your stomach, and works physically rather than by entering the bloodstream.

Rennie can be taken day or night for fast relief. Whether your problem is heartburn, indigestion, acid reflux or trapped wind, you’ll find a product specifically designed to help you.
