How does TUMS work to provide relief from acid indigestion and heartburn?
Antacids, such as TUMS, have a direct and local effect in the esophagus and stomach. TUMS reacts upon contact with the acid and neutralizes it. Heartburn pain results from regurgitation of stomach contents into the esophagus. If the acid is neutralized, an important factor causing the irritation is removed and heartburn is relieved.
