Synopsis

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

Calcium, specifically in the form of calcium carbonate, is scientifically validated as an effective antacid for the treatment of indigestion (dyspepsia) and heartburn. Calcium carbonate acts by directly neutralizing excess gastric acid in the stomach, thereby alleviating the burning sensation and discomfort associated with acid reflux and indigestion. This mechanism is well-understood and has been documented in pharmacological and clinical literature for decades. Over-the-counter antacid products such as Tums and Rolaids commonly use calcium carbonate as their primary active ingredient, reflecting both clinical efficacy and widespread use.

Numerous randomized controlled trials and clinical guidelines support the effectiveness of calcium carbonate for rapid symptom relief in acid-related gastrointestinal disorders, including indigestion. The antacid effect is rapid, typically occurring within minutes. In addition to neutralizing acid, calcium carbonate also provides a supplementary source of dietary calcium, which can be beneficial for some individuals.

However, while effective for short-term relief, calcium carbonate is not recommended for long-term management of chronic indigestion or gastroesophageal reflux disease (GERD) without medical supervision, due to potential side effects such as hypercalcemia and milk-alkali syndrome with excessive use. In summary, the use of calcium carbonate for indigestion is strongly supported by scientific evidence and is a mainstay in both self-care and clinical recommendations for symptomatic relief.
