About Rennie Indigestion Tablets

Rennie Tablets contain two naturally occurring antacids, calcium carbonate and magnesium chloride, that work quickly and powerfully to neutralise excess stomach acid, turning it into water and other natural substances.

Rennie tablets help to reduce the symptoms of acid reflux, indigestion and heartburn by neutralising excess stomach acid, allowing you to enjoy your meals without worrying about the after-effects.

Rennie Sugar-Free tablets work the same way as other Rennie products, just without the sugar. Rennie Sugar Free are suitable for those monitoring their sugar intake.
