      About Gaviscon

      Helping people feel better


      Welcome to the leading over-the-counter brand in Digestive Relief. Our well-established heartburn and indigestion solution provides fast relief and long-lasting protection.

      The Science

      How does

      Gaviscon work?


      Our main ingredient, sodium alginate, is derived from natural seaweed sustainably harvested along the shores of Norway. It creates a protective barrier or raft over the irritating stomach content (which is mostly acid, but also pepsin and bile). The antacid component in the formula - calcium carbonate and sodium bicarbonate - also works to counteract acidity. Gaviscon lasts 2x longer than regular antacids - up to 4 hours.

      Creates a raft

      A protective “raft” stops irritating stomach acid from rising upwards.

      Neutralises acidity

      Antacids counteract acidity for dual relief.

      Long-lasting relief

      Enjoy peace of mind with Gaviscon in your life.
