Medical disclaimer
Everything Longevity Lab publishes is informational and educational only, and none of it is medical advice. We explain scientific research on longevity and aging; we do not diagnose conditions, prescribe treatment, or replace a visit to your doctor.
No doctor–patient relationship
Reading this site, emailing us, or using anything we link to does not create a doctor–patient relationship, a therapeutic relationship, or any other professional relationship between you and Longevity Lab. We are a publisher. We do not know your history, your medications or your test results, and nothing here is tailored to you.
In an emergency
If you think you are having a medical emergency, call your local emergency number — 911 in the United States, 999 in the United Kingdom, 112 across the European Union — or go to the nearest emergency department. Do not use this site, and do not wait for a reply to an email, in an urgent situation.
Talk to a clinician first
Before you change your diet, start a supplement or a medication, begin an exercise program, or order diagnostic tests, check with a qualified clinician — especially if you have a chronic condition, are pregnant or breastfeeding, are under 18, or take prescription drugs. Supplements and foods can interact with medication, and some of them meaningfully change how a prescription behaves. Never delay seeking medical care, and never disregard a clinician’s advice, because of something you read on this site.
Supplements and regulators
Where we discuss a dietary supplement, note that supplements are not regulated the way medicines are. In the United States, statements about supplements have not been evaluated by the Food and Drug Administration, and no supplement is intended to diagnose, treat, cure or prevent any disease. Equivalent limits apply under EU and UK food-supplement rules. We describe what the published research reports; that is not the same as a regulatory approval.
Calculators, scores and estimates
This site explains how various biological-age, risk and screening scores are calculated, and it links to tools that compute them, including tools on our companion site. Every one of those outputs is a statistical estimate for a population, not a diagnosis, a prognosis or a clinical result for you as an individual. A score can be reassuring and wrong, or alarming and wrong. Only a clinician working from your actual examination, history and laboratory results can interpret what any of it means for you.
Individual results vary
Findings we report come from studies of groups of people under specific conditions. Nothing on this site is a promise of a result, and no outcome described here is guaranteed for any individual. Genetics, age, sex, existing conditions, medication and circumstance all change what happens.
Accuracy and updates
We work from authoritative scientific sources and cite them in our articles. Longevity science moves quickly, though, and individual claims can be refined over time. We update our material, but we cannot guarantee that everything on the site is complete and current at any given moment. If you find an error, tell us and we will correct it.
External links
This site links to third-party resources, including scientific databases and health tools. We are not responsible for the content of external sites, their accuracy, or their privacy and security practices, and a link is not an endorsement of everything the destination publishes.
Who this site is for
This site is written for adults, in English, about research conducted largely in North America and Europe. It is not aimed at anyone under 18. Health regulation, product availability and clinical practice differ by country, and nothing here is intended for use where it would be contrary to local law.
Liability
You use the information on this site at your own risk. To the fullest extent permitted by law, Longevity Lab accepts no liability for any loss, injury or damage arising from a decision made on the basis of this material without consulting a qualified clinician. The full limitation is set out in our Terms of Use.
