Best longevity clinics in 2026: scans, ongoing care, treatments and retreats

There is no single best clinic for every need. Compare reviewed options for diagnostic scans, ongoing care, treatments and medical retreats, with the published price and biggest unanswered question beside each one.

The direct answer

Which longevity clinics are worth comparing first in 2026?

There is no single best longevity clinic for every need. Among the 11 profiles Agewell currently reviews, these are the clinics we would compare first: diagnostic assessment: Neko Health or Human Longevity; ongoing membership: Fountain Life or Next Health; procedure-led care: SLS – Stockholms Led- & Smärtspecialist; residential medical retreat: Clinique La Prairie or Lanserhof. This is a shortlist based on the information we could verify, not a universal ranking, proof of outcomes or medical advice.

Four types of care · seven reviewed options

Start with what you need, then compare clinics.

For each option, we show why it made the shortlist, its published price and the biggest question still unanswered. The order within each section is not a ranking.

Type of care

Diagnostic assessment

A one-off scan or coordinated preventive assessment, not an ongoing treatment relationship.

Document checked

Biggest unanswered question

SLS – Stockholms Led- & Smärtspecialist

How the shortlist works

A scan and a retreat do not belong in the same ranking.

Choose the type of care first. Then check the published price, what the clinic actually delivers and the biggest unanswered evidence or safety question.

These recommendations apply only to the clinics Agewell currently reviews and only within each type of care. We do not rank a one-off scan against a membership, treatment course or residential retreat.
