Our Story

More than 40 years of excellence

In 1964, Swedish radiologist Dr Stig Sandmark discovered the benefits of viscosity as a reflux suppressant Gastric Viscosity Control. In 1997, Gaviscon Advance followed, before Double Action made its debut in 2006. Today, Gaviscon is the number one brand for heartburn and indigestion worldwide.

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.

Guardium, our newest product, belongs to the family of “proton pump inhibitors”. It works by blocking the acid pumps in your stomach and while it takes longer to take effect, it provides 24-hour relief.

Guardium can be used alongside Advance and Original for effective relief.
