Alginate In the presence of the calcium carbonate it reacts with the acid in the stomach to form a viscous gel (Raft or a protective barrier) on the surface of stomach contents, thereby reducing symptoms of reflux. That viscous layer acts as a strong physical barrier and helps to keep stomach contents in the stomach as it floats on the surface of the stomach contents. This increase in viscosity of stomach contents and can protect the oesophageal mucosa from acid reflux. This raft stops stomach acid from escaping up into your food pipe.
