Investigation drives diagnosis. Testing confirms it. And every patient enrolled becomes part of the real-world evidence that makes tomorrow's treatment better than today's.
Start with one of our eight condition-specific investigation guides ($29 each). Each is built around a single symptom — chronic fatigue, brain fog, thyroid autoimmunity, iron deficiency, metabolic dysfunction, nerve issues, skin conditions, or immune disease. The guides walk you through what H. pylori is, why it matters, and what the peer-reviewed literature says about the connection between infection and your symptom.
Unsure where to start? The free overview guide covers all eight conditions and helps you narrow down which one matches your experience.
Our at-home H. pylori test kit is a stool antigen assay run by a CLIA-certified US reference laboratory. No order from a provider needed. Results come back in about a week. A positive result opens the pathway to treatment; a negative result is also valuable — it rules out a major driver and narrows your diagnostic focus.
A positive result opens several routes. We'll be straight about the order: the proven baseline comes first, and Welyon's own options are for people who want a supplement-based route or who have already been through standard treatment.
For a confirmed H. pylori infection, antibiotic eradication prescribed by your own clinician is the evidence-backed, guideline-recommended first-line treatment. A positive result is simply what you bring to that conversation — the investigation guides include the language and citations to have it. Everything below is for people who want a supplement-based route, or who have already completed standard treatment.
The self-source guide to building your own multi-mechanism regimen from ~13 commercial ingredients. Everything you need: forms, doses, sourcing, and the evidence behind each one.
The finished, optimized formulation — every active in one standardized, GMP-certified product. Simplified dosing, no sourcing required.
A physician-supervised eradication protocol with clinical oversight and monitoring — the most hands-on tier, for those who want professional guidance throughout.
Welyon runs a pre-registered, real-world evidence study. As the Stack and the physician pathway come online, the outcomes participants consent to share — eradication, symptom change, and secondary measures — are tracked against a single protocol and published; self-source Formulary users can opt in as an exploratory arm. The aim is simple: every step someone takes helps make the next person's better-informed than theirs. It's why Welyon is a research brand, not a storefront.
If your test comes back negative, you don't have active H. pylori infection. That rules out a major driver — but it doesn't solve your symptom. The guides you read during the Understand stage stay useful: they point you toward other causes worth investigating, and they frame the conversation with evidence you've already researched.
No. The at-home test is direct-to-consumer in 46 US states and DC. Four states (NY, NJ, RI, MD) require a clinician order; we're working on a pathway for those.
A positive test result is your ticket to your own physician. Bring the result, mention your symptoms, and ask about eradication. The investigation guides include language and evidence for that conversation.
Yes. The guides are investigations — they connect symptoms to root causes. Many read them to understand better, regardless of whether they test. The test is the bridge from investigation to action.
Every patient enrolled in the HP Stack or HP Program becomes part of our pre-registered observational study. We measure eradication, symptom improvement, and secondary endpoints — and publish the results so tomorrow's patients benefit from today's evidence.
