📋 Editorial & Research Policy · Updated June 2026
Longevix Editorial Policy
How Longevix selects, evaluates and publishes health and longevity information. Our commitment: accuracy over engagement, evidence over trends, transparency over authority.
Our Editorial Mission
Longevix exists to bridge the gap between peer-reviewed longevity science and the public. Our editorial mission is to translate, not create — to make existing, verified science accessible in Hebrew and English without adding interpretation that goes beyond the data.
We do not write "what experts believe." We write "what study X found, with n= participants, DOI= link."
Evidence Hierarchy — How We Evaluate Research
Not all evidence is equal. Every claim on Longevix is labeled with its evidence level:
1
Systematic Reviews & Meta-Analyses
Highest evidence. Pooling data from multiple RCTs. Preferred source whenever available.
2
Large RCTs (n>1,000)
Randomized Controlled Trials with large sample. VITAL, SELECT, STEP-1 fall here.
3
Medium RCTs (n=100–1,000)
Used when no meta-analysis exists. Labeled "Moderate evidence."
4
Small RCTs / Prospective Cohorts (n<100)
Used for emerging topics. Always labeled "Preliminary evidence" or "small study."
5
Animal Studies / Mechanistic
Only cited to explain mechanism, never as standalone evidence for human claims.
What Gets Published vs What Doesn't
✅ What We Publish
- Claims with PubMed-indexed DOI
- Peer-reviewed studies from Tier-1 journals
- Effect sizes, sample sizes, P-values
- Both positive AND null findings
- Longevity targets vs clinical normals — labeled separately
- Limitations of each study
- Evidence strength (Strong / Moderate / Preliminary)
- Contraindications and known risks
❌ What We Never Publish
- Fabricated studies or statistics
- Expert opinion without evidence
- Testimonials as evidence
- Supplement company claims
- Preprint-only findings (not peer-reviewed)
- Animal studies as human evidence
- Study findings extrapolated beyond their scope
- Commercial sponsor-influenced content
Journal Selection Criteria
Longevix preferentially cites from journals with:
- PubMed indexing — mandatory. Every citation must be findable on PubMed.
- Impact Factor ≥ 3 for primary citations. Lower IF journals cited only when no higher IF alternative exists.
- Peer review — mandatory. No preprints, no grey literature.
- Replication — preferably findings replicated in ≥2 independent studies.
Primary journals: NEJM, Nature Aging, The Lancet, JAMA, BMJ, PNAS, Science, eLife, JACC, Diabetologia. Full list: Research Sources →
Conflict of Interest Policy
🔒 Longevix Conflict of Interest Declaration
- No supplement company sponsorship. Longevix does not accept payment from supplement manufacturers for favorable coverage.
- No pharma relationships. GLP-1 medication coverage (Ozempic, Wegovy, Mounjaro) is based solely on published clinical trials.
- No affiliate links that influence which products are recommended.
- Precision Medical Concierge is a Longevix service — this is disclosed wherever relevant.
- Revenue model: Longevix generates revenue through the Precision Medical Concierge service. This does not influence content recommendations.
Content Update Policy
Science evolves. Longevix commits to:
- Reviewing high-traffic pages against new publications annually
- Updating specific claims when contradicted by new Tier-1 evidence
- Displaying "Last Reviewed" date on all substantive pages
- Labeling outdated protocols as "Under Review" rather than removing them
