Betaine HCl

Digestive Supplement

Betaine hydrochloride is an acidifying salt sold for suspected low stomach acid. A small induced-hypochlorhydria pilot showed transient gastric reacidification; evidence for routine symptom treatment and long-term safety remains limited. It is distinct from betaine/TMG.

Pharmacokinetic model

A route-level PK model for betaine hcl is being prepared from published data. Dosing references, studies, and documented interactions are below; the app catalog is updated as models are validated.

  1. Gastric reacidification with betaine HCl in healthy volunteers with rabeprazole-induced hypochlorhydria Yago MR, Frymoyer AR, Smelick GS, Frassetto LA, Budha NR, Dresser MJ, Ware JA, Benet LZ · Molecular Pharmaceutics, 2013 DOI

    Six healthy volunteers with rabeprazole-induced hypochlorhydria received 1500 mg. Gastric pH fell rapidly and remained below four for about 77 minutes on average; this small artificial model does not establish clinical…

  2. Meal-Time Supplementation with Betaine HCl for Functional Hypochlorhydria: What is the Evidence? Guilliams TG, Drake LE · Integrative Medicine, 2020

    Narrative review discusses the rationale and sparse evidence for mealtime betaine HCl. It does not supply controlled evidence for broad symptom claims or a systemic PK model.

2 published studies referenced in the app, each with a plain-language summary.
