Synopsis

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

Sodium bicarbonate, also known as baking soda, is scientifically validated for the temporary relief of indigestion (dyspepsia) and heartburn. Its use is based on its chemical properties as an antacid—it reacts with stomach hydrochloric acid to form sodium chloride, water, and carbon dioxide, thereby neutralizing excess gastric acid and alleviating symptoms such as burning and discomfort. This reaction provides rapid symptom relief, which is why sodium bicarbonate is included as an active ingredient in several over-the-counter antacid products (e.g., Alka-Seltzer, baking soda tablets).

Numerous clinical guidelines and pharmacological references acknowledge sodium bicarbonate as an effective short-term option for acid-related indigestion. However, it is not recommended for prolonged use due to the risk of systemic alkalosis, sodium overload, and potential interactions with other medications. Its efficacy has been demonstrated primarily through its mechanism of action and longstanding clinical use, rather than through large-scale randomized controlled trials, which accounts for a rating of 4 out of 5.

In summary, sodium bicarbonate is a scientifically supported, rapid-acting antacid for occasional indigestion. However, patients with conditions such as hypertension, heart failure, or kidney problems should use it with caution due to its sodium content.
