The 3-in-1 formula that soothes occasional heartburn by forming a barrier and buffer for gastric acid, our convenient liquid Heartburn Soothe shots protect the digestive tract and help rebuild the stomach lining. With alginate, prickly pear extract and buffering extracts, Heartburn Soothe is the result of detailed scientific study with the world-renowned Roskamp Institute. Found in brown algae, alginate possesses a viscous gel texture that quickly absorbs 200-300 times its weight in water. In the stomach, it forms a “raft” that floats on the stomach's acid pocket. That keeps the acid from entering the esophagus, soothing the sensation of occasional heartburn while also giving the esophageal tissue an opportunity to rebuild itself.
