Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Bicarbonate (commonly sodium bicarbonate, also known as baking soda) is used for relief of gas and bloating, and this use is supported by scientific understanding of its mechanism. Bicarbonate acts as an antacid, neutralizing excess stomach acid. When mixed with gastric acid in the stomach, it produces carbon dioxide gas, water, and sodium chloride (table salt). The reaction temporarily increases the pH of stomach contents, which can help alleviate symptoms of dyspepsia (indigestion), including bloating and discomfort related to excessive acidity.

Several over-the-counter antacid formulations contain sodium bicarbonate, and its use for symptomatic relief of bloating due to acid-related indigestion has been recognized in clinical guidelines and pharmacological texts. However, while bicarbonate can help with bloating associated with acid and rapid gastric emptying, it is less effective for bloating caused by other mechanisms, such as irritable bowel syndrome or gas produced by bacterial fermentation in the intestines. The conversion of bicarbonate and acid to CO2 can, in some cases, temporarily increase belching as the gas is released, which some people find helpful for symptomatic relief.

Systematic reviews on antacid use, including sodium bicarbonate, focus on relief of heartburn and acid indigestion, not specifically on “gas and bloating.” Therefore, while there is scientific rationale and some clinical use for bicarbonate in this context, the evidence base is moderate rather than robust, justifying a rating of 3.
