How we score longevity clinics in Spain

At LongevityMap, every clinic receives a quality score from 0 to 100 calculated on the information the clinic itself declares, with the signals and their weights published. No sponsorships, no subjective opinions, no conflicts of interest. Here we explain exactly how we do it.

Our principles

Objectivity

We score with declared and recorded data, never with opinions or subjective assessments.

Independence

No clinic can alter its position or its Score through payment. The only indirect relationship that exists —the status of verified clinic— is explained in the frequently asked questions on this same page.

What the Quality Index measures

The Quality Index scores how complete each clinic's profile is: what information the clinic has declared and in how much detail. It is not a medical assessment, nor an opinion about the clinic, nor a score anyone reviews by hand — it is computed by a deterministic algorithm over five observable signals, and the same profile always yields the same number. These are the signals and their weight.

The five signals of the Index

Catalogued treatments
Up to 6 treatments count; from the sixth on nothing more is added, so a long catalogue cannot buy the top.
42 points
Clinic description
It counts that the description exists and how long it is, with diminishing returns and a cap at 200 characters. It does not measure whether the text is good, and it cannot: that is what the cap is for.
28 points
Photographs
10 points
Cover image
10 points
Public phone number
10 points
The last three are yes or no: the profile either has them or it does not.
100 points

The Index is expressed on a scale of 0 to 100 points. As at 11 August 2026, across the 353 published listings, the observed values ranged between 28 and 100 points. This is a figure observed on that date and not a limit of the Index, which may take any value on the scale.

Address, website and location score nothing: they are requirements for being in the catalogue at all. All 352 public profiles meet them (measured 10 August 2026). A criterion everybody meets is not a criterion — it is a tariff.

The per-treatment score — framework published, no data yet

This framework describes how we will evaluate each treatment across four dimensions once the evaluation is in service. As of today no treatment has a per-dimension score and no profile displays one: the number you see on the profiles is the Quality Index described above. We publish the framework in advance so it can be audited before it scores, not to suggest that it already does.

Scientific basis — Each evaluation criterion is supported by published scientific literature (PubMed, Cochrane).

Our methodology rests on a proprietary classification framework cataloguing more than 500 clinical and operational attributes of clinics. The framework describes what CAN be evaluated; not every attribute takes part in every recommendation.

1. Equipment

30% of score

We evaluate the technology each clinic uses: brand, model, year of manufacture, certifications and technical specifications. Modern, well-maintained equipment is the foundation of a safe and effective treatment.

Criteria we evaluate:

Brand and model of main equipment
Year of manufacture and maintenance
CE, FDA or equivalent certifications
Technical specifications (power, temperature, frequency)
Documented calibration and periodic reviews

Practical example:

A profile that declares the make, model and year of its main device — «Juka CryoAir cryogenic chamber, 2024» — scores higher than one that only says «cryotherapy chamber», because the first is checkable and the second is not.

2. Practitioner

20% of score

We analyze the qualifications of the professional administering the treatment: degree, years of experience, specific certifications and continuing education. The difference between a good and an excellent result is often in the hands that perform it.

Criteria we evaluate:

Official degree and license number
Years of experience in the specific treatment
Specialized certifications (manufacturer, association)
Demonstrable continuing education
Professional-to-patient ratio per session

Practical example:

A licensed physician with 8 years of experience in ozone therapy and certification from the Spanish Ozone Therapy Society scores higher than a technician without formal medical training.

3. Protocol

25% of score

We evaluate whether the clinical protocol is based on published scientific evidence, includes prior patient assessment, is personalized (not generic) and includes post-treatment follow-up.

Criteria we evaluate:

Based on studies published in PubMed/Cochrane
Prior patient assessment (medical history, contraindications)
Personalization based on patient profile and goals
Documented informed consent
Post-treatment follow-up protocol

Practical example:

A NAD+ IV clinic that performs prior blood work, adjusts the dose to weight and goals, and schedules 4-week follow-up scores higher than one that applies standard 500 mg to everyone.

4. Results

25% of score

We measure reported results quantitatively: biomarker improvement, documented patient satisfaction, repeat rate and objective clinical data when available.

Criteria we evaluate:

Quantitative improvement data (biomarkers, measurements)
Patient satisfaction (standardized surveys)
Patient repeat rate
Documented before/after objective cases
Reported adverse effects and incidence rate

Practical example:

A PRP clinic that documents a 60% improvement on VAS pain scale in 100 patients with 6-month follow-up provides stronger evidence than anonymous testimonials.

The step-by-step process

Clinic registration

The clinic registers on LongevityMap and declares its treatments, equipment, professionals and protocols.

Ownership verification

The platform verifies ownership of the listing when it is claimed, through a documentary check that may be denied. Every review of the index is recorded internally.

Algorithmic scoring

The algorithm computes the Index from the published signals. The same criteria for every clinic, with no manual intervention.

Publication and monitoring

The initial index may be updated after a review, in accordance with the platform's quality and reliability criteria.

How to interpret the score

Score	Category	Meaning
90–100	Excellent	Complete profile: broad catalogue, long description, photos, cover image and public phone number.
80–89	Very good	Almost every signal published. Some detail left to complete.
70–79	Good	A good part of the profile published, with room in some signal.
60–69	Acceptable	The basics are there, but signals are still unpublished.
40–59	Needs improvement	Several signals unpublished. Worth cross-checking with the clinic before deciding.
0–39	Low quality	Profile with little declared information. It tells you what the clinic has published, not how it works.

Frequently asked questions about our methodology

Can clinics pay to improve their score?

No clinic pays for its position in the results: no paid plan modifies the ranking order. The order is determined by quality and reliability criteria. Contracting a plan only enables the clinic to claim and manage its listing, a requirement to obtain the status of verified clinic, which is one of the criteria that influence the ranking. In this sense, there is an indirect relationship between contracting a plan and position, described in detail in the conditions applicable to clinics.

Where does each clinic's Quality Index come from?

The Quality Index, which scores the completeness of the clinic's listing, is generated deterministically from the five completeness signals described on this page; it is not generated from the clinic's public rating on Google or from any other third-party source.

How often is the score updated?

The index may be recalculated at LongevityMap's initiative, for example when a listing is incorporated or after a manual review. LongevityMap does not perform an automatic recalculation when a clinic edits its data. Every review of the index is recorded internally.

What happens if a clinic doesn’t provide all the data?

Missing data is reflected in a lower score. We don’t actively penalize, but a clinic that catalogues its treatments, writes its description and publishes photos, a cover image and a phone number will always score higher than one that leaves the bare minimum. Transparency is rewarded.

Can I trust the score to choose a clinic?

The score is an objective comparison tool, not a medical diagnosis. It tells you what each clinic has published and in how much detail, comparably — not how it works or what results it achieves. We always recommend consulting directly with the clinic and your doctor before making a decision.

Why LongevityMap

We're not a directory · we don't accept pay-for-ranking · we don't invent reviews.

What we do, and what can be checked

Ownership of every listing is checked against documentation before verification is granted.
Every review is anchored to a specific appointment: no appointment, no review.
The clinic runs its calendar, its prices and its patients from its own panel.
Real Spanish invoicing: an invoice compliant with RD 1619/2012 and a register for the clinic's accountant.
The Quality Index criteria are published and anyone can read them.

5 curation axes that no generalist marketplace solves.

Generalist vertical marketplaces do not differentiate an infrared sauna validated by Laukkanen JAMA 2015 from one without studies. For longevity that is the primary filter.

We evaluate each longevity clinic on declared qualifications, equipment with declared specifications, price transparency and the clinical safety criteria published in our guides (G6PD, anticoagulation, pregnancy, etc.).
