Rennie Extra

Rennie Extra

Rennie Extra tablets provide relief from heartburn and acid indigestion in just two minutes.

Rennie Extra has a powerful long lasting formula that works in two ways to relieve the painful symptoms of heartburn.

First, the antacids quickly soothe the burning pain in the chest and neutralise excess acid in the stomach, turning it in to water and other natural substances. Second, the alginic acid forms a long lasting protective barrier in the stomach to help stop acid from rising up into your chest.
