Synopsis

Source of validity: Scientific
Rating (out of 5): 4

Calcium, specifically in the form of calcium carbonate, is widely used as an over-the-counter remedy for acid indigestion (also known as heartburn or dyspepsia). The scientific justification for its use lies in its role as an effective antacid. Calcium carbonate works by directly neutralizing excess gastric hydrochloric acid in the stomach, thereby increasing the pH and alleviating the burning sensation associated with acid indigestion. Numerous clinical studies and pharmacological reviews have demonstrated the efficacy of calcium carbonate in providing rapid, short-term relief of heartburn and acid indigestion symptoms. Products such as Tums® and Rolaids® are commonly recommended by healthcare professionals for this purpose.

Calcium carbonate's use is supported by both longstanding tradition and robust scientific evidence. The mechanism of action is well understood: as a strong, fast-acting antacid, calcium carbonate reacts with stomach acid to form calcium chloride, water, and carbon dioxide, resulting in quick symptom relief. The evidence rating is not maximal (5/5) because, while effective for occasional symptoms, calcium carbonate is not suitable for long-term management of chronic gastroesophageal reflux disease (GERD) due to potential side effects like milk-alkali syndrome and rebound acid secretion with excessive use.

In summary, the use of calcium (as calcium carbonate) for acid indigestion is justified by scientific validation, is safe for short-term use, and is supported by both clinical practice and pharmacological evidence.
