Betaine
Betaine hydrochloride is a chemical compound sometimes used to increase the acidic content of the stomach (hydrochloric acid) as well as to increase potassium levels in the body. This natural remedy is recommended to increase digestive efficiency, especially for those with insufficient acid content in the stomach.
Low stomach acid levels can result in insufficient digestion of foods in the stomach or slow digestion (indigestion) and the resultant bloated feelings and gassiness. Supplementing with betaine hydrochloride is said to increase stomach acid content and thereby help reduce such symptoms.
