How Do Hydrochloric Acid Supplements Work?
Betaine is a B-vitamin found in high concentration in beets. Betaine hydrochloride (HCl) is a salt of betaine and HCL. Once in the stomach, it releases the hydrochloric acid, which is the same as your stomach acid.
In a clinical study of healthy volunteers, betaine HCL supplements effectively reduced stomach pH by about 4.5 within about 30 minutes.
