As a supplement

Talk to your doctor or pharmacist.

Roll Call does not check drug interactions or assess personal safety.

A compound combining betaine (a naturally occurring compound found in beets and other foods) with hydrochloric acid, sold as a supplement intended to add acidity in the stomach.

Why it’s used

Taken by some who believe they have low stomach acid, in the hope of supporting digestion.

What the evidence says

There is little to no rigorous clinical trial evidence in humans evaluating betaine hydrochloride supplementation for digestive symptoms or stomach acid levels. Its use rests largely on physiological reasoning and anecdotal reports rather than controlled studies, so it is not possible to say from the available evidence whether it produces the intended effect.

Context

Insufficient dataToo little has been studied to say either way.
