THE PRACTICE

Medicine that looks ahead, not back.

LongevityNow is a private medical practice in Zürich built around one idea: measure the body before problems announce themselves. Advanced diagnostics find risk years early. Physician-supervised therapies (NAD+, cryotherapy, metabolic care) act on what the data shows. And a personal plan keeps the results compounding, year after year.

01 – Diagnose

A baseline deeper than any routine check-up.

02 – Treat

Therapies chosen by your results, supervised by specialists.

03 – Sustain

Re-measured, adjusted, and kept on track for years.

IS THIS FOR YOU

You feel fine.
Fine is not a measurement.

  • You want a complete health baseline.

    Especially from your forties on: a clear, measured picture of where your body actually stands today.

  • Your energy, sleep, or recovery has slipped.

    You feel broadly fine, but not quite like yourself, and you want to understand why before it becomes something.

  • Heart disease or cognitive decline runs in your family.

    You would rather know your own numbers early than inherit a diagnosis you never saw coming.

  • You want weight and metabolic support that lasts.

    Not another diet: a medically guided plan measured in glucose, insulin, and lipids, not only kilograms.

  • You want prevention led by doctors, not wellness trends.

    Evidence-based medicine, applied earlier, without supplements to sell or outcomes we can’t support.

NOT SURE WHERE TO START

Ten questions.
One clear next step.

Ten short questions. We’ll point you to the right starting place: diagnostics, metabolic, recovery, or a direct consultation.

WHY EARLY MATTERS

Don’t wait for aging to show up as illness.
Measure it. Understand it. Change it.

  • 20 yrs

    Arterial disease can build for two decades before a first symptom, and stays most changeable early.

  • Earlier

    The sooner a risk is measured, the more can usually be done about it. Time is the lever prevention runs on.

  • Daily

    Sleep, movement, nutrition, and stress are among the strongest levers we can work with, every single day.

WHAT WE MEASURE

Aging is natural.
How you age is personal.

Six systems decide most of how a body ages. We measure each one, and build your plan around what they actually show.

01

Cardiovascular

Arterial imaging, advanced lipids (ApoB, Lp(a)), inflammatory markers.

02

Metabolic

Glucose, insulin sensitivity, lipid composition, body composition.

03

Inflammation

Systemic inflammatory load and the markers that track it over time.

04

Sleep

Duration, depth, and circadian alignment, and what is interfering.

05

Cognition & nervous system

Neurological and stress-recovery signals, led by a neurologist.

06

Movement & lifestyle

Strength, activity, nutrition, and the behaviours that drive most of the result.

HOW IT WORKS

A simple loop, run with discipline.

Measure first, act on what we find, then keep measuring, for years.

  1. 01AssessMeasure the baseline.
  2. 02PlanSet the priorities.
  3. 03TreatApply what your data calls for.
  4. 04TrackRe-measure with the same tools.
  5. 05SustainHold the gains for years.

PROGRAMS

Two programs. One standard of care.

Both programs are built on the same clinical rigour; the difference is depth. Longevity Complete is our full diagnostic, therapy, and year-long follow-through program. Longevity Entry is the focused way to begin, with everything that matters most from day one.

DOCTOR-LED, NOT TREND-LED

Trends promise everything.
Medicine promises what it can prove.

It starts with a conversation.

Every plan begins with a consultation and a full medical history, never with a fixed package of treatments.

Diagnostics are chosen for you.

We select tests for your profile and goals, and your physician reviews every result with you in plain language.

Every therapy is supervised.

Cryotherapy and intravenous protocols include safety screening. Some conditions mean a therapy is not appropriate, and we will tell you so.

We don’t over-promise.

Blood work runs through accredited Swiss laboratories, and we describe what the evidence does, and does not, support.

The information on this site is general and is not a substitute for individual medical advice. Suitability for any assessment or therapy, including cryotherapy and intravenous protocols, is determined during consultation and may not be appropriate for everyone.
