What the name means
Clinics use the name in different ways. A 2025 editorial in the journal Aging notes that such clinics are also called age-management practices, personalised health centres or wellness-longevity hybrids, and that many present themselves as wellness providers rather than medical facilities (Demaria, 2025).
So this guide sorts each provider it lists into one of seven types. Only longevity clinics, hospital check-up units, diagnostics centres and medical wellness retreats can be ranked, and a hospital unit only when it names a doctor in charge of its assessments.
The types of provider we list
| Type | What it is | Ranked? | We list |
|---|---|---|---|
| Longevity clinic | A doctor-led clinic whose main service is a preventive health or longevity assessment with a written plan. | Can be ranked | 125 |
| Hospital check-up and longevity unit | An executive health, check-up or longevity unit inside a hospital or hospital group, or a stand-alone executive health centre. Ranked only when it names a doctor in charge of the assessments. | Ranked when it names a doctor in charge | 68 |
| Diagnostics centre | A centre whose main service is screening or diagnostics, such as whole-body MRI, with a doctor's report. | Can be ranked | 25 |
| Medical wellness retreat | A residential programme with doctors on site, usually in a resort or clinic hotel. | Can be ranked | 11 |
| GP practice | A general practice that offers health checks or screens as part of its family-doctor service. Listed, never ranked. | Listed, never ranked | 8 |
| Doctor-led IV clinic | A clinic with a named doctor in charge whose main services are IV drips and related treatments, not a longevity assessment with a written plan. Listed, never ranked. | Listed, never ranked | 31 |
| Wellness and IV studio | A studio offering recovery, IV or wellness services with no named doctor in charge and no doctor-led assessment. Listed, never ranked. | Listed, never ranked | 104 |
What they offer
Longevity clinics usually offer tests followed by a personal plan. The tests can include genetic sequencing, advanced imaging and full-body scans, microbiome analyses and epigenetic tests. The plan can include exercise, nutrition advice, supplements and sleep advice. Some clinics sell yearly memberships, and some offer IV drips or more experimental treatments such as stem-cell infusions, peptide injections and plasma exchange (Demaria, 2025).
Each clinic report shows whether the clinic says it offers a consultation with a doctor, a written plan and follow-up. The evidence behind the tests and treatments differs widely, so reports list each test and treatment the clinic names with our evidence label:
- Established: Recommended in clinical guidelines for defined uses.
- Emerging: Early human evidence; benefits for healthy ageing not yet shown.
- Unproven: No good evidence of benefit for healthy ageing; regulators have issued warnings or advise against routine use.
- Depends on use: Established for some medical conditions, unproven as a longevity treatment.
Two examples. A whole-body MRI is labelled Unproven: in April 2023 the American College of Radiology said there was not enough evidence to recommend whole-body screening for people with no symptoms, risk factors or family history of disease (ACR, 2023). Stem cell therapy is labelled Unproven: the US Food and Drug Administration says the only stem cell products it has approved are blood-forming stem cells from cord blood, for disorders of blood production, and that it has received reports of blindness, tumour formation and infections linked to unapproved products (FDA page current as of 8 April 2024, FDA).
How it differs from a routine check-up
Some health systems offer checks free. In England, the NHS invites adults aged 40 to 74 who do not already have conditions such as heart disease or diabetes to a free NHS Health Check every 5 years; it estimates the risk of heart disease, diabetes, kidney disease and stroke (NHS page reviewed 14 August 2023, NHS). In the United States, the US Preventive Services Task Force publishes the screening tests it recommends for adults (USPSTF).
A longevity assessment can include tests that these programmes do not, such as whole-body MRI or biological age tests. Ask what each test is for, and what you would do differently with the result.
How to read a clinic report
Each report shows the licence state with the register and the date of the check, the doctors named, the tests and treatments with their evidence labels, the prices published, the public ratings with their dates, and a score out of 100 with the working shown. How we score sets out the rules, and How we check licences lists the registers.
