AYUN.

What AYUN actually is

Switzerland’s first walk-in longevity clinic, opened on Uraniastrasse in Zürich in July 2024. The proposition is access — a storefront format where readers can buy individual diagnostic tests and treatment sessions rather than committing to a packaged programme tier. The model lowers the entry price meaningfully: single IHHT sessions start at CHF 115 and the Essential check-up costs CHF 2,499, a fraction of the cost of a full outpatient longevity day.

This is, on its own terms, a useful addition to the category. The threshold price for engaging with longevity medicine has been too high, and AYUN’s modular structure is the right answer to that problem.

What you get

The diagnostic offering is organised into check-ups: Essential (CHF 2,499, 19 blood values), Women’s Health (CHF 3,999), Complete (CHF 5,299, 63 values) and Extended (CHF 7,299, 70+ values). Individual tests include an epigenetic profile with SNP analysis, Omniscope immune age, mitochondrial function, VO₂ max, CGM, HRV and microbiome. At the top sits AYUN 360, a CHF 25,000 base programme that adds full-body MRI and full genome sequencing. The lead doctor is Dr. Dr. med. Oliver Boekels; Dr. Natalia Trpchevska is scientific director.

The treatment menu — hyperbaric oxygen (CHF 260 a session), intermittent hypoxic-hyperoxic training (IHHT, CHF 115) and red light — is where the practice’s revenue centre of gravity sits. Sessions are bookable individually. Cryotherapy, contrast therapy and the Exercube stopped being sold as standalone treatments on 7 July 2026.

Lifestyle and nutrition coaching is included in most diagnostic intakes; the multidisciplinary team includes longevity specialists alongside the medical staff.

Where it sits in the directory

AYUN is the right purchase for a specific reader: someone who wants to start with longevity-relevant diagnostics, locally and at low commitment, before deciding whether to invest in the deeper workups at the upper tier.

For that reader, the Essential or Complete check-up is a credible first baseline — it will identify the markers that justify (or do not justify) a deeper outpatient or residential investment.

For the reader who is already past that first decision and wants the deepest workup the category can produce, AYUN is not it. The directory leaders run substantially more diagnostic depth and substantially less treatment-product pressure.

Where it falls short on evidence

Two specific points worth naming.

The evidence base for IHHT — intermittent hypoxic-hyperoxic training — in healthy adults is materially thinner than the marketing implies. The mechanism is interesting; the randomised data on healthspan-relevant outcomes in non-hypoxia-stressed populations is sparse.

Hyperbaric oxygen for non-clinical longevity indications sits in similar territory. The evidence for clinical indications (diabetic ulcers, decompression illness, certain stroke recovery) is robust; the evidence for healthy-population longevity benefit is preliminary.

We credit AYUN for offering these treatments transparently, with patient consent and clinician explanation. The marketing copy is more confident than the evidence currently supports.

The verdict

A useful entry point. Not a directory leader. Worth knowing about for the regional reader testing the category at lower commitment, particularly the entry check-ups.

A clinic that lowers the entry price for serious diagnostics is, on balance, good for the field. A clinic that ladders into treatments with thin evidence is a different proposition. AYUN is both.

Does AYUN earn from the treatments it recommends?

Yes. We score this as a structural conflict of interest. Walk-in clinic that bundles diagnostics with on-site treatments — hyperbaric oxygen, intermittent hypoxic-hyperoxic training and red-light sessions all generate margin alongside the workup. AYUN scores 17/25 on conflict freedom.

— 03

Is AYUN physician-led?

Yes. Medical leadership: Dr. Dr. med. Oliver Boekels (Lead Doctor); Dr. Natalia Trpchevska (Scientific Director). AYUN scores 20/25 on medical supervision.

How does AYUN rank among longevity clinics?

AYUN ranks #14 of 19 in the 2026 Longevity Clinics ranking, with 72/100 (Good, with caveats). An accessible introduction to the category at a fraction of the residential cost. Lighter on physician depth than the upper-tier choices.
