Longevity Clinics Explained: What They Do and Who They Are For

There is a conversation happening right now in the world of health and wellness that I genuinely cannot stop thinking about and want to share more about to everyone. Maybe you have seen it expanding in the news over the last few years but it has been growing exponentially as a part of our day-to-day lives and day-to-day conversations (Think: Bryan Johnson and Blue zones).  It's not about the newest supplement stack, the latest fasting protocol, or even the wellness getaways or retreats I love so much (and yes, I still love them). It's about something bigger, something more proactive, something that feels like a true paradigm shift in how we relate to our own bodies and our future selves.

It's about longevity. And the spaces, the clinics, the science, the protocols, that are completely reshaping how we think about our health and our future selves.

If you've been paying attention to the wellness world lately, you've probably started hearing these words more and more. And I don't mean in a vague, trend-y way. I mean real, science-backed, data-driven centers that are asking the question most conventional medicine never does: What if we could detect and address the causes of decline before they ever become a problem?

That's what longevity medicine is, and I think it's one of the most exciting spaces of our time. (No surprise why I actually work in the longevity space)

So What Even Is a Longevity Clinic?

A longevity clinic is not your regular check-up. It's not a spa. And it's definitely not a quick fix. Think of it as the intersection of preventive or functional medicine, advanced diagnostics, and deeply personalized wellness science, all focused on one goal: helping you live not just longer, but better and more vibrantly, for longer.

Where conventional medicine often reacts to illness, longevity medicine gets ahead of it. These clinics measure your biological age versus your chronological age, identify what's quietly building up in your body (or quietly breaking down), and create a completely individualized protocol to address it. It's your health, seen through an entirely different lens.

The services typically include full-body imaging, comprehensive biomarker panels (sometimes measuring 150–200+ health markers in a single visit), genetic and epigenetic testing, cognitive assessments, metabolic profiling, hormonal analysis, and personalized action plans with ongoing monitoring. Some clinics also offer regenerative therapies, IV nutrient protocols, cryotherapy, hyperbaric oxygen, and more. Similar to our biohacking suite at Powercube. 

The "why" behind all of this is simple, and it echoes something I've written about before: your health is not a luxury, it is the foundation for everything else. Longevity medicine just operationalizes that belief at the highest possible level.

The Parisian Pioneers: ZOĪ and Maison Epigenetic

I am slightly obsessed with what is happening in Paris right now on this front, and if you know me, you know that's not just because Paris is my forever city.

ZOĪ (on Place Vendôme, naturally) is one of the most advanced preventive health centers in Europe, and it is genuinely redefining what a medical check-up can feel like. ZOĪ offers an intensive 4-hour diagnostic experience that screens nearly 200 biomarkers, includes advanced imaging, microbiota analysis, a 24-hour neurotransmitter and cortisol profile, and 11 functional examinations. The whole thing is designed to detect early signs of cardiovascular issues, metabolic dysfunction, oncological risk factors, hormonal imbalances, and neurological changes — before any symptoms have a chance to arrive at your door uninvited.

What I love about ZOĪ is that it also integrates a full year of digital support through their app after the check-up, with a medical concierge and personalized action plan. Their medical committee includes specialists from leading American and European institutions. This isn't wellness as a trend. This is medicine as it should be, meeting you where you actually are.

The entry-level ZOĪ Pulse (ideal for under-40s) starts at approximately 3,600 euros for a year-long program. For those who want the complete ZOĪ Life experience, the protocol goes deeper still.

Maison Epigenetic, located in a gorgeous mansion in the 16th arrondissement, is a different kind of offering entirely,  and one that I think is particularly brilliant for people based in or regularly passing through Paris. Founded by Dr. Valérie Leduc, a leader in preventive medicine, Maison Epigenetic is built around the science of epigenetics,  the study of how our lifestyle, environment, and daily habits literally influence how our genes express themselves. Which I have been studying and reading about since literally 10 years ago when I understood every choice I have made has had an impact on my health. 

What makes Maison Epigenetic stand out is that it's designed for integration, not escape. You don't have to take a week off to benefit. Their signature 1-Hour Boost compresses recovery, metabolic training, hormonal stimulation, detox, and stress reduction into a single session. Their biomarker-led check-up assesses sleep quality, stress, energy, hormonal balance, immunity, inflammation markers, minerals, and heavy metals. Programs are spread across multiple sessions and tracked over time, so every intervention is measured and refined.

This is longevity as a lifestyle, embedded into your city life — not something you only access on a retreat once a year. And that feels like the future to me.

The Swiss Standard: Chenot Palace Weggis, Clinique La Prairie, and Clinique Nescens

If Paris represents the urban, integrated, ongoing approach to longevity, Switzerland represents the intensive, immersive, go-deep-and-reset model. And Switzerland does it at an entirely different level.

Chenot Palace Weggis, on the shores of Lake Lucerne, is genuinely one of the most transformative health experiences on the planet. It has won the World's Best Detox Programme award five years running, and if you've ever heard anyone who's been, you'll understand why. The Chenot Method — developed over 50 years of scientific research, is a full cellular reset. Their 5,000 sqm medical spa combines bioenergetic assessments, Traditional Chinese Medicine, advanced Western diagnostics, cryotherapy at -110°C, and a highly specific 850-calorie daily protocol designed to induce deep purification and cellular regeneration.

This is not for the casual wellness enthusiast. It's for someone who is ready to go all in on their body's potential and emerge transformed. Programs start from approximately CHF 5,500 for seven nights. The combination of the science, the setting, the care, and the Alpine beauty is, by all accounts, unlike anything else.

Clinique La Prairie, on the shores of Lake Geneva, has been pioneering cellular therapy and anti-aging protocols since 1931. It is the gold standard — favored by people at the absolute top of their fields who know that their body is their greatest asset. The approach combines luxury hospitality with medical science of the highest order, covering everything from cellular revitalization and metabolic optimization to aesthetic and regenerative medicine.

Clinique Nescens, located in Genolier (just 25 minutes from Geneva) and nestled inside one of Switzerland's most prestigious medical institutions, is founded by Professor Jacques Proust — a world-renowned expert in the biology of aging. Their signature La Cure Reset program is a 7-day transformative experience that combines epigenetics, microbiota analysis, regenerative therapies, and advanced preventive medicine. It's designed not just to restore your baseline, but to recalibrate your entire trajectory around aging.

What Clinique Nescens does particularly well is integration: genetics, epigenetic profiling, personalized monitoring, and lifestyle medicine all working together. Guests also have access to a panoramic view of Lake Geneva and the Alps, which honestly feels like a form of medicine all on its own.

For those who want the Nescens expertise in a more urban setting, La Réserve Genève offers their protocols in a gorgeous lakeside resort just 5 minutes from the city — proof that this level of care doesn't always require going off-grid.

The American Model: Fountain Life and the Rise of the Hybrid Longevity Club

In the United States, the longevity clinic model is evolving rapidly, and it's happening at serious scale. What's interesting about the American approach is how it's blending medical-grade diagnostics with the access and energy of a membership club.

Fountain Life — co-founded by Peter Diamandis and Tony Robbins, is arguably the most prominent name in this space right now. Named Longevity Clinic of the Year in 2025, it operates across multiple flagship centers in New York, Dallas, Florida, and beyond. Their APEX membership offers whole-body MRI scans, AI-powered diagnostics, advanced genetic testing, full biomarker analysis, and regenerative medicine protocols. What's particularly powerful is their approach to early detection: they've identified potentially life-threatening conditions in 14% of seemingly healthy members. 14%. That number alone tells you why this kind of medicine matters.

The annual membership starts at approximately $20,000, which is a significant investment,  but consider what you're investing in. The goal isn't just to live longer. It's to live with full capacity, clarity, and energy for all of it. That’s why Bryan Johnson and 

On the more accessible end, Next Health has expanded rapidly across the US (with 16+ locations) as a hybrid wellness and longevity center, combining diagnostics, IV therapy, hormone optimization, infrared sauna, and performance tracking through tiered memberships that open this world to a broader audience. They represent the democratization of longevity medicine, and I think that is genuinely important.

Human Longevity Inc., founded by genomics pioneer Craig Venter, is another major player — offering whole genome sequencing and deep data-driven health profiling, particularly valuable for those who want to go truly deep on their genetic blueprint and what it means for their future health.

Who Is This For, Really?

Here's what I want to say clearly, because I think there's a perception that longevity medicine is only for the ultra-wealthy or the biohacking elite: it's not.

It is, of course, a significant financial investment at the top tier. A Chenot week in Switzerland, a Fountain Life membership, a ZOĪ Life check-up — these are not casual expenses. But the spectrum is wide. A ZOĪ Pulse assessment, a Maison Epigenetic membership for ongoing urban protocols, or entry-level longevity testing is increasingly accessible, and the principles behind all of this, knowing your data, understanding your body, making proactive choices, are available at many price points. As an example, Powercube’s diagnostics and Biometrics testing around Wellness age is less than 300 chf. The biohacking suite brings 4 state of the art technologies such as red light therapy, cryotherapy, float thereapy and hydrogen to a fraction of the price compared to the programs at these clinics. But its more than just doing one of these programs or trying out a therapy, its integration into your daily life. 

Beyond cost, I truly believe this world is for anyone who has decided to take their health from reactive to proactive. It's for the high-performing professional who feels their body is their most important asset and treats it accordingly. It's for the person who has watched a parent or grandparent decline from something that might have been caught earlier, and has decided their story will be different (partially my case as well). It's for the woman in her 40s who knows something is off but can't get answers from conventional medicine. It's for anyone who refuses to accept that aging poorly is inevitable.

And honestly? It's for anyone who has connected to their why. Because as I've written before, when you know your why. your deep, unshakeable reason for wanting to live well,  every investment you make in your health starts to feel less like a cost and more like a commitment to the life you're building.

A Final Thought

We are living in a moment where, for the first time in human history, we actually have tools precise enough to look inside our bodies with real clarity, to see what's coming before it arrives, and to course-correct our habits with intention.

That is extraordinary. And I don't think we should skip over it just because you may be someone who has not hit your 40s yet. It’s important to already understand what this could do to help our healthspan today. 

Whether you start with a comprehensive biomarker panel at a clinic in your city, a transformative week in the Swiss Alps, or simply by reading everything you can on the topic, start. Get curious. Ask better questions about your body. Treat your health not as a background concern but as a central pillar of the life you want to live.

The future of your longevity is not something that happens to you. With the right information, the right support, and the right mindset, it's something you get to consciously create.

And that, to me, is one of the most powerful realizations of all.
