Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Betaine hydrochloride (Betaine HCl) has traditionally been used as a digestive aid, particularly for those believed to have low stomach acid (hypochlorhydria), which can impair protein digestion. The rationale is that Betaine HCl, when ingested, increases the acidity of the stomach, thereby enhancing the activity of pepsin, the primary enzyme responsible for breaking down proteins in the stomach. The use of Betaine HCl for this purpose appears in older naturopathic, alternative medicine, and some early 20th-century pharmaceutical references. However, rigorous scientific evidence supporting its effectiveness in improving protein digestion in individuals with hypochlorhydria is limited.

A small number of clinical studies from several decades ago explored the use of Betaine HCl for hypochlorhydria, typically using gastric pH monitoring as an endpoint. These studies suggested that Betaine HCl could temporarily lower gastric pH in some individuals with low stomach acid, potentially improving the environment for protein digestion. However, there are no large, well-controlled modern trials confirming improvements in actual protein digestion, symptom relief, or nutritional status. Most of the support for this use remains anecdotal or based on historical practice rather than robust scientific validation. Modern guidelines do not routinely recommend Betaine HCl for this indication, and safety data are limited, particularly for individuals with normal or increased stomach acid.

In conclusion, the use of Betaine HCl to support protein digestion is justified primarily by tradition, with weak supporting evidence (rating: 2/5) and little modern scientific validation.
