AYUN

AYUN operates as Switzerland's first walk-in longevity clinic, though appointments are required rather than true walk-in access. The clinic's business model emphasizes preventive medicine grounded in understanding your biology before disease develops. Where conventional medicine waits for symptoms, AYUN's philosophy is to decode your health status while you are still well, using that early understanding to guide long-term optimization. The clinic is located in central Zurich and draws clients from across Switzerland and neighboring regions, many drawn by the relatively accessible pricing and insurance coverage compared to competing clinics.

The clinic's flagship offering is the Longevity Check-up, a physician-guided comprehensive health assessment that runs four to five hours. This is not a quick blood draw and consultation. The appointment involves multiple interactions with different specialists, including doctors, medical staff, nutritionists, and sports scientists, each contributing their expertise to a multi-dimensional picture of your health. The extensive duration reflects the depth of assessment. You do not move through in thirty minutes and leave with a handful of recommendations. Instead, you spend significant time with professionals who can answer questions, explain findings in real time, and begin discussing how the results apply to your life.

AYUN structures its check-ups in three tiers, allowing clients to choose the depth of assessment that suits their needs and budget. The Essential Check-up, priced at CHF 2,499, is the entry-level option. It includes 19 blood values, genetic panel analysis, body composition assessment using professional equipment, VO2 max testing to measure cardiovascular fitness, and comprehensive physician consultation lasting 60 minutes, followed by a 90-minute follow-up review. For many people seeking a solid preventive health picture without diving to the deepest level of detail, the Essential package provides genuine insight into metabolic health, genetic predisposition, fitness capacity, and body composition. The blood work may seem limited compared to the higher tiers, but 19 values cover core metabolic functions and provide a reasonable foundation.

The Complete Check-up, at CHF 5,299, expands the assessment significantly. It includes everything in the Essential package plus an increase to 63 blood values, adding much greater depth to metabolic, hormonal, and organ function assessment. It adds ten days of continuous glucose monitoring, a tool that reveals how your body responds to different foods and stress levels in real time, which can be genuinely revelatory for people discovering metabolic sensitivities. The Complete package also includes physical flexibility and balance assessments, recognizing that movement and physical capacity are dimensions of longevity. Nutritional consultation and sports science consultation are added, moving beyond blood data into practical guidance on diet and training for your individual biology.

The Extended Check-up is the most comprehensive, priced at CHF 7,299. It includes all Complete features plus expansion to 70 blood values, adding even more detailed markers. It adds mitochondrial function testing, recognizing that mitochondrial health is foundational to cellular aging. Heart-rate variability monitoring is included, a measure of nervous system regulation and stress resilience. Gut microbiome analysis examines your bacterial ecosystem in detail, given the growing understanding that microbiome composition influences immunity, metabolism, and even brain function. The physician consultation is extended to 120 minutes, and specialized microbiome counseling is included, allowing deep discussion of how your specific bacterial patterns should guide dietary and lifestyle choices.

All three packages conclude with personalized longevity reports that integrate the data and provide medical interpretation. Clients receive more than raw numbers. A physician synthesizes the findings and explains what they mean for your health trajectory. This interpretation phase is crucial because raw biomarker data can be confusing or misunderstood without expert explanation. AYUN includes that guidance in every package, not as an upsell.

One significant practical advantage AYUN offers is insurance coverage. Many Swiss supplementary insurance policies cover at least part of a Longevity Check-up. Reimbursement varies significantly by insurer and policy level. CSS and KPT cover up to CHF 500 per check-up. Sanitas covers between CHF 1,000 and CHF 1,500 depending on plan. Swica covers CHF 500 to CHF 600 for check-ups, with additional coverage for coaching and training services. Sympany covers CHF 300 to CHF 600 annually. The maximum potential reimbursement under a good supplementary insurance plan can reach CHF 4,000 per year. To be clear, these are partial reimbursements, not full coverage, but they reduce the out-of-pocket cost considerably compared to paying the full price privately. AYUN offers a cashback guarantee, meaning if your supplementary insurance should have reimbursed but did not, the clinic covers the gap. This removes a major uncertainty that deters many people from preventive health spending.

The clinic staff model is worth noting. A single doctor does not perform the entire check-up. Instead, you interact with physicians who can answer medical questions, medical technicians who perform the tests and imaging, nutritionists who discuss diet and its relationship to your biomarkers, and sports scientists who interpret your fitness testing and make training recommendations. This multi-disciplinary approach recognizes that optimizing health requires different expertise. A cardiologist's perspective on your heart-rate variability is different from a sports scientist's, and both matter. A nutritionist can discuss diet in ways a physician often cannot, with deeper practical knowledge of food choices and their effects.

AYUN also offers a range of complementary treatments available through the clinic beyond the core check-ups. These include hyperbaric oxygen therapy, marketed for cellular health, red light therapy, and cryotherapy. Hyperbaric oxygen has well-established uses for conditions like decompression sickness and non-healing wounds, but the evidence for its benefit in a healthy person seeking general cellular health is thin and disputed. The clinic offers IHHT, intermittent hypoxic hyperoxic training, which involves controlled exposure to varying oxygen levels and is proposed to improve cardiovascular capacity and stress resilience, another intervention where the research base is still early and outcomes for the general wellness market remain unsettled. Continuous glucose monitoring is available as an extended option beyond the packages. These additional therapies are not bundled into the core check-up but are available if a client's results suggest they might be helpful, or if a client wants to pursue them after understanding their baseline health status.

Pricing flexibility is another practical feature. For clients for whom the full price is a barrier, AYUN offers installment financing through Klarna. The Essential Check-up can be paid in installments starting at CHF 208 per month over a 12-month plan. The Complete package starts at CHF 442 per month, and the Extended at CHF 608 per month. This brings the services into reach for more people and acknowledges that significant health investment is easier to manage across time than as a lump sum.

The clinic's positioning is distinctly different from luxury spa-based longevity retreats or boutique clinics aimed exclusively at ultra-high-net-worth clients. AYUN is premium but not gatekept by extraordinary expense. It is serious medicine but accessible through insurance support and financing. The four- to five-hour check-up is substantial enough to provide real insight without requiring a multi-day retreat or weeks of follow-up appointments. For a Swiss resident or someone willing to travel to Zurich for a few hours, AYUN offers a practical entry point into comprehensive preventive longevity assessment with medical oversight and a genuine multi-disciplinary team.
