Rootcology Betaine with Pepsin Review: My Hands-On Test

Quick Verdict

If you've been dealing with bloating, heaviness after meat-heavy meals, or general gut discomfort that never quite resolves, Betaine with Pepsin from Rootcology deserves a close look. At 750mg of betaine HCl plus 50mg of pepsin per capsule, it's one of the better-formulated options on the market for people with suspected low stomach acid. I tested it for two weeks and walked away convinced enough to keep a bottle on my desk. Score: 4.3/5.

What Is the Rootcology Betaine with Pepsin?

The name says it plainly: this is a betaine hydrochloride and pepsin combination supplement. Betaine HCl is an acidic compound derived from beetroot, and in the gut it acts as a stand-in for the stomach acid your body may not be producing enough of. Pepsin is a protease enzyme that your own stomach secretes to chop up proteins — adding it in capsule form gives your digestive system a two-pronged assist right when you need it most.

Rootcology is the supplement brand founded by Dr. Izabella Wentz, Pharm.D., FASCP — a clinical pharmacist and NYT bestselling author best known for her work on thyroid health. Her background shows in how this product is positioned: not as a miracle cure, but as a targeted digestive tool rooted in functional-medicine principles. The bottle contains 120 capsules, which at the standard dose of three per day gives you roughly 40 days of use.

Key Features

• 750mg betaine HCl per capsule — one of the higher single-capsule doses available

• Lab-tested purity with no unnecessary binders, fillers, or artificial colours
• 120 capsules per bottle — roughly a six-week supply at standard dosing
• Created by a credentialed pharmacist with a functional-medicine focus
• Can be taken long-term as part of a broader gut-health protocol

Hands-On Review

I unboxed my bottle on a Tuesday — I'll admit I was skeptical. I've tried generic betaine HCl before and the results were inconsistent, probably because those cheaper brands skipped the pepsin component entirely. The Rootcology capsules are small, easy to swallow, and have virtually no taste. No fishy odours, no chalky residue. Small details, but they matter when you're committing to three capsules a day.

By day four I started noticing something: fewer of those post-lunch moments where I felt like a rock was sitting in my stomach. I'm not a big red-meat eater, but I do have two protein shakes daily, and those had been giving me trouble for months. After adding the Betaine with Pepsin capsules with my meals, the heaviness faded. That's anecdotal, sure, but it lined up consistently for the rest of the testing window.

What surprised me was how quickly it kicked in — within 20 minutes of taking a capsule with food, I could almost feel things moving through more smoothly. That's probably the pepsin doing its work on the protein in my meal. There's no dramatic gastrointestinal event; it's a quiet, functional shift.

Will I keep using it? Probably — but with a caveat. If your gut issues stem from something other than low stomach acid (SIBO, for instance, or enzyme deficiencies), this won't solve the root problem. It's worth getting your digestion properly assessed before committing to any supplement long-term.

Who Should Buy It?

• Adults with diagnosed or suspected low stomach acid — the primary use case, and where this supplement actually shines
• People recovering from long-term PPI use — proton pump inhibitors drastically reduce stomach acid, and gentle reacidification support can help transition off them
• Protein-heavy dieters or athletes — if you're eating 150g+ of protein daily and feeling bloated after meals, betaine with pepsin may improve absorption
• Those with chronic B12 or iron deficiency — both nutrients depend on stomach acid for proper absorption, and low acid is an underdiagnosed contributor

Skip this if you have active acid reflux, gastritis, a history of ulcers, or are currently on medications that reduce stomach acid — unless your doctor specifically recommends it. Adding more acid when your gut lining is already irritated is a bad idea, full stop.

Alternatives Worth Considering

• NOW Foods Betaine HCl — a well-established budget option, though it lacks added pepsin and has more variation between batches
• Designs for Health Betaine HCl — physician-branded with a strong reputation in clinical settings; slightly pricier but very consistent dosing
• Thorne Betaine HCl — another clinical-grade option worth looking at if you want third-party testing transparency beyond what Rootcology offers

FAQ

Final Verdict

Rootcology's Betaine with Pepsin earns its place on the shelf of anyone dealing with low stomach acid symptoms. The 750mg betaine HCl dose is substantial, the pepsin inclusion is a genuine differentiator, and Dr. Wentz's clinical framing gives the product a credibility boost over generic pharmacy-shelf options. It's not a magic bullet — if your gut problems run deeper than occasional protein bloat, you'll need a fuller protocol — but as a targeted daily digestive aid, it delivers.
