Longevity Clinics in Europe: How to Compare Them Well

You have three tabs open and each one promises a longer life. One shows a Swiss laboratory, another talks about fasting beside a lake and the third offers diagnostics, IVs and a suite overlooking the Mediterranean. Prices and names change, but the question is the same: how much is useful medicine and how much is experience?

The uncomfortable answer is that there is no “best longevity clinic in Europe” for everyone. There are also no comparable public outcome data that allow these centres to be scored fairly. We can compare something more honest: what each clinic publicly says it does, what information it publishes and which questions it should answer before accepting a booking.

First, decide which problem you want to solve

“I want to live longer” is too broad for choosing a clinic. A useful question is more specific: I want to review cardiovascular risk; I need to understand persistent fatigue; I want supervised fasting; I want to restore physical capacity; I need to organise menopause symptoms; or I want a preventive assessment and a plan for home.

If the category is still unclear, start with what a longevity clinic is. To prepare a budget, read how to calculate the cost of a longevity clinic. If your main goal is not eating for several days, our guide to therapeutic fasting explains the risks and limits before you choose a centre.

Eight European examples, without a podium

The table does not recommend or certify centres. It summarises the positioning each brand displays publicly and turns that marketing message into a question you can verify. Programmes, clinicians, inclusions and conditions can change.

Centre	Publicly stated focus	Critical question before booking
Clinique La Prairie, Switzerland	Longevity programmes, diagnostics and high-end medical hospitality.	Which tests and consultations are included, which decision does each change and what follow-up remains at home?
SHA Spain, Alicante	Integrative programmes for longevity, weight, detox, performance and lifestyle.	Which part of the package is medical assessment, which is wellness and which items cost extra?
Buchinger Wilhelmi, Germany and Marbella	Therapeutic fasting with medical care, nutrition, activity and education.	Am I a candidate for fasting, which medicines need adjustment and how is refeeding managed?
Lanserhof, Germany and Austria	Personalised medical programmes linked to Mayr medicine, diagnostics and recovery.	Which clinical objective drives the programme and what evidence supports each proposed intervention?
VIVAMAYR, Austria	A Mayr concept centred on digestive health, diagnostics and complementary medicine under supervision.	How is the digestive focus integrated with cardiovascular risk, strength, sleep, medication and other priorities?
MAYRLIFE, Austria	Goal-based medical programmes with different stay lengths and optional modules.	What is the total price after accommodation, tests, supplements, medicines and add-ons?
Chenot Palace Weggis, Switzerland	Seven-night programmes with diagnostics, consultations, treatments and a proprietary diet, organised around detox.	What does detox mean in my case and which clinical measure will evaluate the result?
ZEM Altea, Alicante	A preventive programme with diagnostics, neurocognition, nutrition, performance and therapies described as regenerative.	What is the exact product or procedure, what is its indication and which regulatory authorisation covers it?

The seven questions that make a stay comparable

1. Who carries clinical responsibility?

Ask for the name, specialty, role and a way to verify the licence of the responsible professional. Ask who reviews your history, who authorises treatment, which cover is in place and where an emergency is referred. “Medical supervision” can mean very different things.

2. Which decision does each test change?

A long biomarker list looks impressive, but it can also create incidental findings, false positives and more testing. Before agreeing to blood work, imaging or an ageing clock, ask three things: which question it answers, what an abnormal result would change and where it would be confirmed.

3. Is the treatment indicated for you?

The right sequence is problem, assessment, options and consent. If the catalogue determines treatment before anyone knows your history, the order is reversed. Ask for evidence for your goal, expected benefits, alternatives, contraindications and adverse events.

4. What is the regulatory status?

Words such as regenerative, cellular or exosomes do not describe an authorisation. In Europe, some gene-, tissue- or cell-based products may be advanced therapy medicines. Request the exact name, manufacturer, indication, competent authority and consent document. An available therapy is not automatically approved for every use.

5. What does it really cost?

Compare itemised budgets. The advertised price may exclude the room, special tests, treatments, supplements, medicines, transport or reviews. Also ask what happens if the doctor rules out an intervention already included in the package and what the cancellation terms are.

6. What do you take home?

A report without priorities may end up in a drawer. Look for an understandable summary, complete results, a problem list, concrete changes, responsibility for each next step and a review timeline. If follow-up requires another trip, that should be clear before payment.

7. How will you know whether it worked?

Define one or two measures tied to the goal in advance: blood pressure, ApoB, glucose control, aerobic capacity, strength, sleep, symptoms or adherence. A changed ageing clock or feeling renewed may be interesting, but neither replaces a well-chosen clinical or functional outcome.

Three terms that should not be mixed

Therapeutic fasting: a Buchinger study of 1,422 participants observed changes during supervised fasts lasting 4 to 21 days. It was an observational study without a randomised control group and does not show that every person, duration or centre will get the same result. Fasting may require medication changes and is not suitable for everyone.

Detox: this may describe reducing alcohol and ultra-processed food, eating differently, resting or losing weight. It may also be used for vague claims about “removing toxins”. Ask for the substance, measurement and mechanism. If these cannot be named, you are comparing an experience, not a testable clinical claim.

Regenerative medicine: this covers very different products and procedures. The EMA explains that advanced therapies based on genes, tissues or cells have specific regulatory categories. The FDA has documented harms linked with unapproved regenerative products. The practical rule is simple: exact name, authorisation, indication and adverse-event monitoring.

Where Progevita sits in this comparison

Progevita publishes the article and offers residential stays in Cofrentes, Valencia. That commercial relationship means it cannot act as a neutral judge of its own quality. It therefore receives no score, podium or superiority claim.

If you put it on your shortlist, use the same questions: responsible physician, tests that change decisions, treatments indicated after assessment, full budget, safety, deliverable results and real follow-up. Do the same with every centre. A useful comparison is not about believing the brand that writes the most. It is about obtaining concrete answers in writing.

Frequently asked questions

Is there a best longevity clinic in Europe?

There is no universal winner. A clinic built around fasting, Mayr medicine, preventive diagnostics or luxury medical hospitality serves different goals. The best choice defines your problem, explains which decisions will change and offers a safe, verifiable plan.

How do I know which clinic fits my goal?

First write down what you want to solve: cardiometabolic risk, symptoms, performance, supervised fasting, recovery or a second opinion. Then compare medical time, tests that answer that question, justified interventions and follow-up, not the number of treatments in the catalogue.

How can I check that clinical responsibility is real?

Ask for the name and role of the responsible physician, how to verify their licence in that country, who reviews results and who responds if there is a complication. A beautiful hotel, a white coat or the word medical does not prove a clinical structure by itself.

What should I ask about tests?

Ask what each test is for, which decision it could change, which false positives it may produce and whether confirmation elsewhere will be needed. More biomarkers do not automatically mean better medicine, especially without interpretation, context and follow-up.

What should I ask about treatments?

Ask for the indication, evidence for your goal, alternatives, contraindications, adverse events and regulatory status. If cells, exosomes, peptides, plasma or regenerative therapies appear, request the exact product name and applicable authorisation before paying.

How do I compare the total cost of a stay?

Request a budget that separates accommodation, consultations, tests, included treatments, extras, medicines, supplements, transport, cancellation and follow-up. A nightly rate or base programme price rarely makes two centres comparable without that list.

Are fasting, detox and regenerative medicine equivalent?

No. Supervised fasting is a nutritional intervention with specific evidence and risks; detox can describe anything from rest and diet to poorly defined claims; regenerative medicine covers products and procedures with very different regulation and evidence.

Why is Progevita mentioned in a guide published by Progevita?

Progevita offers residential stays, so there is a commercial conflict that must be visible. This update does not score it or declare it the winner. If you compare it, apply exactly the same questions about physician, tests, indications, total price, safety and follow-up.
