Synopsis

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

Alkali substances, such as sodium bicarbonate (baking soda) and other alkaline compounds, are scientifically validated treatments for overacidity, particularly in the context of gastric hyperacidity or acid indigestion. The primary mechanism involves neutralization of excess gastric acid (hydrochloric acid) in the stomach, which can relieve symptoms such as heartburn and dyspepsia. This effect is well-established and forms the basis of many over-the-counter antacid formulations, which commonly include alkali bases like magnesium hydroxide, calcium carbonate, or sodium bicarbonate.

Clinical guidelines and pharmacological textbooks recognize the use of alkali-containing antacids as a first-line treatment for mild, occasional episodes of gastric overacidity. The efficacy is supported by decades of clinical use and experimental data showing rapid pH elevation in the stomach following ingestion of these substances. However, for chronic or severe conditions such as gastroesophageal reflux disease (GERD), longer-acting medications (like H2 blockers or proton pump inhibitors) may be preferred due to concerns about rebound acidity and electrolyte imbalance with excessive alkali use.

In summary, the use of alkali for supporting or treating overacidity is strongly supported by scientific evidence, especially for short-term, symptomatic relief. Its mechanism, safety profile (when used as directed), and effectiveness are well-characterized in the medical literature.
