How Gaviscon Advance works

Gaviscon Advance forms a protective barrier that helps keep stomach acid from rising back up the oesophagus (food pipe).

We know how disruptive heartburn and acid reflux can be, which is why Advance is designed for long-lasting relief (up to 4 hours)- to help you get on with your day.

Gaviscon Advance’s extra strength formulation has twice the concentration of sodium alginate - forming a strong and resilient ‘raft’ in the process.

The liquid formulation does not contain sugar or gluten and can be taken during pregnancy or breast-feeding.
What’s more, Advance has the lowest sodium content of any product in the Gaviscon range.

Sodium Alginate

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.
