How we work
The rules we follow when we turn peer-reviewed research into the pages you read here.
Where our evidence comes from
Every claim check and insight starts with a PubMed search across peer-reviewed literature. We search each topic from at least three angles: the direct claim, the biological mechanism, and the broader context (related interventions, populations, and outcomes).
We only cite papers we can point to. Every article lists its sources with DOIs, so you can always read the primary research yourself. We never invent citations, and we never cite a paper we could not verify.
How verdicts work
Claim checks get one of four verdicts. Supported: multiple quality studies point the same way. Partially supported: real evidence exists, but it is mixed, small, or narrower than the claim. Insufficient evidence: too little relevant research to call it. Debunked: the research contradicts the claim.
Separately from the verdict, an evidence score (1-5) reflects the quality and quantity of research on the topic - a claim can be well-studied and still be false. A debunked claim with strong research keeps a high evidence score and a Debunked verdict.
What we will not do
We do not recommend dosages, brands, or treatments. We describe what studies measured and found - decisions about your health belong with you and a qualified clinician.
We do not sell supplements, and we do not take sponsorships from supplement companies. No affiliate links to products we evaluate. Our revenue comes from readers: guides and (soon) the premium insight library.
AI assistance and human review
The "Is It Legit?" checker uses AI to search PubMed and summarise the evidence for new claims. Freshly generated pages are marked internally and kept out of search-engine indexing until they pass review against our quality bar: real citations, faithful summaries, bounded conclusions.
Long-form insights follow a fixed structure - recommendation, findings, mechanism, limitations - and every published piece must include an honest limitations section: who the evidence does not apply to, and what the studies could not show.
Updates and corrections
Science moves, and our pages move with it. We periodically re-check published content against newer research; every content page shows when it was last checked or updated.
If we got something wrong, we fix the page and note the change. Spotted an error? Write to hello@longevinsights.com and include the page link - we read everything.
