Betaine HCl is supplemental stomach acid for people with hypochlorhydria (low stomach acid). Symptoms: bloating after meals, undigested food in stool, acid reflux (paradoxically — low acid causes LES relaxation). Jonathan Wright protocol: start with 1 capsule (650mg) with protein-containing meal, increase by 1 capsule each meal until warmth felt in stomach, then back off 1 capsule. NOT the same as betaine anhydrous (TMG) — betaine HCl provides HCl for digestion, while TMG is a methyl donor. --- *Reviewed by the Dose AI Research Team and Clinical Advisory Board* *Last updated: 2026-04-06*
