How Gaviscon Peppermint works

Why change what’s worked for over 30 years? You can enjoy relief from heartburn today with Gaviscon’s most iconic formulation.

It all starts with sodium alginate. Refined from brown seaweed harvested from the shores of Norway, this effective formulation acts as a barrier against discomfort and provides instant relief.

When the sodium alginate comes into contact with the irritating gastric acid, the alginate becomes a “raft”. It forms a protective barrier over your stomach contents, stopping acid from rising and soothing the burning sensation in your chest.

In short? You get fast relief from those unpleasant sensations that both heartburn and indigestion sufferers know so well.  

The Gaviscon formulation does not enter the bloodstream. It’s a safe and effective product that’s free from gluten - with Gaviscon Peppermint Liquid containing no sugar at all.

As a second line of protection, sodium bicarbonate and calcium carbonate act as antacids, countering the problematic acid in the process. The protective barrier lasts for up to 4 hours.

For fast and effective aid, Gaviscon Peppermint has you covered.

A sodium alginate solution

Sodium alginate is extracted from the cell walls of seaweed. It helps the stomach block rising acid, the root cause of the discomfort heartburn and indigestion sufferers know so well.


All the products in the Gaviscon range are designed to combat heartburn and indigestion. We have been around for more than 40 years,pioneering the treatment of heartburn and indigestion and providing long-term and instant relief for millions.

Gaviscon is made using all-natural seaweed and is perfectly safe for many to take. Most people who take Gaviscon do not experience any side effects. If you do experience any side effects, they are highly likely to be mild and will go away when you stop taking Gaviscon.

Speak to your doctor if you experience:
