Longevity Lab is an independent publication about the science of longevity. Our material is written by the Longevity Lab editorial team and built on peer-reviewed research, with every significant claim traceable to a published source. We explain difficult topics in health and life extension in plain language, starting with the idea the whole field is built on: Longevity. This page sets out who produces that material and the rules we work by, so you know what you can trust here.
Who writes our articles
Our articles are produced by the Longevity Lab team: writers who specialize in health, nutrition, physical activity and the biology of aging, including what does and does not count as a Biomarker of aging. We do not publish anonymous content under the names of specialists who do not exist, and we do not credit articles to invented experts. The project team is accountable for everything we publish.
We deliberately avoid listing fictional doctors or “medical reviewers”. Instead of imitating expertise, we rely on transparent sourcing: every significant claim in our articles can be checked against links to scientific publications and the published positions of established health organizations.
What our articles are based on
We rely on the sources with the highest level of evidence, and we always cite them in the article.
- Peer-reviewed scientific publications and systematic reviews (PubMed, Cochrane and other databases).
- Positions and recommendations from established public health organizations.
- Data from large clinical trials and meta-analyses.
At the end of each article we publish a source block with links, so you can verify the facts yourself. When a topic is still poorly studied or the evidence conflicts, we say so plainly instead of presenting a hypothesis as settled fact. We treat competing measurement methods the same way: our companion overview of Biological age tests: what to measure and how to choose a method compares the available approaches and explains how to pick one, rather than crowning a single winner.
How we check facts
Every article goes through an internal review. We check the key claims against the primary sources, separate results obtained in humans from findings in animals, and state how strong the evidence is. We avoid sensational headlines and promises of “miracle cures”, which in the longevity field are a reliable marker of bad faith. The same rule governs the calculators on our companion site Smart Longevity: the PhenoAge Calculator — biological age from a blood test implements a model published in a peer-reviewed journal rather than a scoring system of our own.
We update our articles as new data appears. Aging science moves quickly, and we work to keep the information current.
Important: this is information, not a prescription
Longevity Lab content is educational and informational. It does not replace a consultation with a doctor and it is not individual medical advice. Any change to your diet, supplements, physical activity or treatment should be agreed with a qualified clinician, especially if you have a chronic condition, are pregnant, or take medication — and the same goes for acting on Laboratory tests you ordered yourself. Reference material such as How to read your labs and manage your longevity is there to help you understand your own numbers and ask sharper questions at your appointment, not to stand in for the clinician who interprets them.
Transparency and feedback
We value our readers’ trust and we are open to corrections. If you spot an inaccuracy or have a question about an article, write to us through the contacts page. We take reasonable objections seriously and make the fix.
