Longevity Clinics: What They Offer and What Evidence Supports It

What longevity clinics typically offer, which services regulators have warned about, and how to weigh a clinic's claims against the evidence, without naming any clinic.

What this page is

"Longevity clinic" is not a protected or standardized term. This page describes the kinds of services researchers and regulators discuss, what evidence exists for each, and questions that help you judge a claim. We do not name, rate or recommend any clinic. This is information, not medical advice.

What clinics say they do

A 2024 review in GeroScience described private clinics as meeting consumer demand for guidance on healthy longevity. Its description of such care included a medical history, physical examination and clinical tests to detect early signs of age-related decline, and interventions such as lifestyle changes, supplements, repurposed drugs, and social and environmental measures. [1]

A second 2024 paper, in Aging and Disease, said that longevity clinics use aging clocks and biomarkers in healthy people for "preclinical prevention," and that at present there is no universally accepted standard model for a longevity clinic. [2] A 2026 narrative review said there is an absence of clear guidelines for longevity. [3] Both of these are proposals by authors who support the field, not independent audits of clinics, and we found no published study that audited what private clinics actually deliver. Proper evidence not found on clinic outcomes.

Ten questions to ask any clinic

Which exact test or treatment, and what is it approved or validated for?
What published human trial supports it, in people like me, measuring health outcomes rather than lab scores?
What are the harms, and how are adverse events handled?
Is the product FDA approved, and for what? Is the use off-label? See off-label prescribing.
Is it offered under a registered trial with oversight?
Who profits from the tests and the products?
Will my own doctor see the results?
Does the claim cite mouse results? See claim check: mouse results.
What happens if a result is borderline? Does it lead to more tests?
What does it cost, and is there a package that must be bought up front?

The US Federal Trade Commission's health-products guidance says health benefit claims generally need competent and reliable scientific evidence, and that randomized, controlled human trials are the most reliable form. [9]

Frequently asked questions

Are longevity clinics regulated as a category?

We found no source describing a category-wide standard. Authors say there is no universally accepted model. [2]

Are stem cell or exosome treatments for aging approved?

FDA says unapproved regenerative products have been linked to reports of blindness, tumors and infections. [5]

Does a lab-tested "biological age" prove a treatment works?

No. A biomarker change is not a health outcome; experts call for validation. [4]

What evidence should a clinic show?

Human trials with health outcomes. FTC guidance names randomized controlled trials as the most reliable form. [9]

How to read the evidence labels

Labels used on this page: approved medicine, established, promising but limited, insufficient evidence, no good evidence of benefit, evidence of harm and marketing claim. Where we looked and found nothing usable we write "Proper evidence not found."

What regulators have said

FDA says it regulates regenerative medicine products, that broad marketing of unapproved ones continues for a wide range of diseases and conditions, and that these products need FDA approval and, before approval, oversight in a clinical trial. [5] It says it has received reports of blindness, tumor formation and infections. [5] FDA also says that if you are charged for these products or offered them outside an FDA-overseen trial, you are likely being deceived and offered a product illegally; and that people are sometimes told a product is registered on clinicaltrials.gov or with FDA to suggest compliance, which is often false. [5]

On NAD+, FDA reminded compounders that food-grade NAD+ is not suitable for making sterile injections without processing because of high risk of contamination with microbes and endotoxins. It reported adverse events including severe chills, shaking, vomiting and fatigue, some requiring treatment. [6]

In a 2025 warning letter, FDA said exosome products from a seller were unapproved new drugs, and that a "research and investigational" statement did not change this. [7] In a 2026 warning letter to a peptide seller, FDA said "research use only" labels did not change that products were intended as drugs for human use. [8]

Safety

Anyone with a health condition, who is pregnant, or who takes medicines should talk with their own doctor before any unproven test or treatment. Do not stop prescribed medicine because of a clinic's advice without your own doctor. See longevity experiments and safety and claim check: longevity doctors versus guidelines.
