Editorial Policy

Last updated: October 3, 2026

This policy explains how S2Y researches, reviews, updates, and corrects health-adjacent content across s2y.us and s2yhealth.com. It is published for readers, clinicians, researchers, and reviewers who want to understand what our content can and cannot promise.

1. Who is responsible for this content

S2Y LLC, a Delaware limited liability company (8 The Green STE B, Dover, DE 19901, United States), operates this site. S2Y LLC designs and distributes general wellness devices and evidence-informed digital health content. Our editorial team is responsible for the claims on these pages, and we publish this policy — including a corrections process — so that responsibility is explicit rather than assumed.

2. Why this policy exists

S2Y publishes content about transcutaneous vagus nerve stimulation (tVNS), hypochlorous acid (HOCl), Long COVID, autonomic nervous system regulation, and related health topics. Because these subjects overlap with medical decisions, we aim to be clear about what our content can and cannot claim.

Our goals are to:

  • make evidence-informed health information easier to understand;
  • stay honest about uncertainty, individual differences, and the limits of wellness content;
  • clearly separate wellness products from medical treatment.

3. How we research content

When we publish or update a page, we look for high-quality sources first. We prefer guidance and research from organizations such as the National Institutes of Health (NIH), NCCIH, CDC, WHO, and peer-reviewed journals, as well as registered clinical trials on ClinicalTrials.gov.

  • We favor systematic reviews, meta-analyses, and randomized controlled trials when available.
  • We distinguish a proposed mechanism (biological plausibility) from demonstrated clinical evidence, and do not present a mechanism as proof of benefit.
  • We treat preliminary, pilot, and open-label findings as preliminary — never as established fact.
  • We separate traditional or wellness concepts from medical claims.

4. Citation standards

We try to link every health claim to the strongest primary source a reader can inspect directly — a PubMed record, a registered trial, or an institutional guideline — rather than a vague reference or a secondary summary. For transparency, we maintain an open S2Y Research Library: a structured index of the studies behind our content, each listing study type, population, sample size, a hedged key finding, stated limitations, and the PMID or DOI.

5. Language and claims (hedged wording)

We avoid absolute promises such as "cures", "guarantees", "eliminates", or "reverses" a condition. We use hedged, evidence-calibrated language instead — for example, "research suggests a possible association", "may support", "preliminary evidence indicates", or "clinical data reported a reduction of up to X%". Where evidence is mixed, early, or population-specific, we say so, and we revise wording when better evidence changes the conclusion.

6. Safety framing

S2Y's devices are marketed as general wellness devices, not as medical devices intended to diagnose, treat, cure, or prevent any disease, unless explicitly cleared or approved for such use. Content near any purchase point discloses contraindications and cautions (for example, implanted pacemakers, epilepsy, pregnancy, or application near the carotid sinus) so that safety information travels with the product, not buried in fine print.

7. Updates and corrections

We review pages when new evidence, product changes, or reader feedback make a revision necessary. Material updates are dated. If you find an error, an outdated citation, or an unclear health claim, email hello@s2y.us with the page URL and a short description, and we will review and correct it.

8. Disclaimer

S2Y is not a medical provider. Content on this site is for educational and general wellness purposes only. It is not a substitute for diagnosis, treatment, or advice from a licensed medical professional. Always consult your clinician before starting, changing, or stopping any health practice or intervention.
