All six, ranked by cost per capsule

Plain vs. with-pepsin vs. with-gentian: what the difference actually is

NOW Foods Betaine HCl 648mg, Vegetarian Formula (120ct) is the only plain (no-pepsin) product tracked here — labeled 648mg betaine HCl per capsule, no added enzyme, and the second-cheapest per capsule of the six. Most retail betaine HCl is sold bundled with pepsin, a protein-digesting enzyme, because both are marketed for the same "protein digestion" pitch — Nutricost Betaine HCl + Pepsin 790mg (240ct) is both the cheapest per capsule of all six products and the best-value pepsin-containing pick, at $0.07/capsule. Pepsin is typically animal (porcine) derived, a real consideration for vegetarian or vegan buyers; the plain betaine HCl pick above is vegetarian-labeled by contrast. Doctor's Best Betaine HCl Pepsin & Gentian Bitters (120ct) is the only product here that adds gentian root extract, a traditional bitters ingredient — a real formulation difference, not evidence this specific blend was tested in any cited trial. None of these formulation choices changes the underlying evidence picture: no citation in this evidence base isolates pepsin's or gentian's individual contribution, and none tested any of these six specific branded products.

The premium and pepsin-free options: paying more doesn't buy more evidence

Thorne Betaine HCl & Pepsin (225ct) is the most expensive of the five pepsin-containing products at $0.21/capsule, positioned on third-party certification and manufacturing quality — a real quality-assurance signal, not a stronger clinical evidence base; no trial in this pack tested this specific branded product either. BIOptimizers HCL Breakthrough, Pepsin-Free (90ct) is the most expensive per capsule of all six tracked products, at $0.31/capsule, and it's pepsin-free by design. ⚠️ Its own marketing copy makes claims — general gas and heartburn relief — that go beyond what this pack's evidence supports; no RCT here tested this or any branded betaine HCl product for general symptom relief in a healthy, undiagnosed population. Flagging this explicitly rather than repeating the claim.

Reading the cost table honestly

The cost-per-capsule figures above assume the lowest label-stated serving — 1 capsule, with a protein-containing meal — not a multi-capsule "titrated" dose. Most labels on these six products direct 1-3 capsules per meal depending on how someone responds, so a real-world regimen following the (unvalidated) titration protocol described on the dosage guide could cost 2-3x the single-capsule figure shown here. None of the six listings disclose a per-capsule betaine-HCl-vs-pepsin milligram split confirmed against the physical Supplement Facts panel — the two products with a specific mg figure in this comparison (NOW's 648mg plain capsule and Nutricost's 790mg blend) come from the manufacturers' own label copy, not an independent re-check. Bottle size also matters more here than in many categories: Nutricost's 240-count bottle spreads the same list price over far more capsules than a 90 or 100-count bottle, which is most of why the cheapest-per-capsule pepsin product isn't necessarily the cheapest bottle on the shelf.

Who should not buy any of these

Regardless of price or formulation: do not use betaine HCl if you have a history of peptic ulcer disease, gastritis, or GERD. Do not combine it with NSAIDs or corticosteroids. Do not take it alongside a PPI (omeprazole, esomeprazole) or an H2 blocker (famotidine, cimetidine) without talking to the prescriber first — taking an acid supplement against a prescribed acid reducer works directly against the reason it was prescribed. Persistent reflux, indigestion, or bloating should be evaluated by a clinician, not self-treated with any product on this page.
