Responsibility for your healthy years.
Too often, treatment came too late. We chose a different path – prevention that is precise, effective and sustainable.
We identify risks before they become noticeable and accompany your health year after year. True prevention is a conscious, lifelong commitment to a better, healthier life.
With YEARS, we pursue a clear vision: To prevent age-related diseases early, reliably and systemically.
We built YEARS from the ground up as a platform that is fully standardized, physician-led and scientifically founded. Based on epidemiological insights, supported by cutting-edge diagnostics and focused on measurable outcomes for every client.
Dr. med. Jan K. Hennigs
Medical and Scientific Director

YEARS aims to realign medicine – away from reactive treatment, towards proactive prevention.
We enable a deep understanding of your body through cutting-edge diagnostics – from organ functions and body composition to innovative biomarkers. Based on this data, we identify the most effective lifestyle and medical interventions to optimize your health and vitality. Through continuous monitoring, our recommendations remain precise, personalized and always state-of-the-art – for the best possible support of your healthy years.
What makes the difference? Prevention by system.
YEARS is the only healthspan clinic built on a clinical first-principles framework. We have standardized diagnostics from the ground up: Every client goes through the same rigorous protocol – and every result is scientifically founded.
Standardized Protocols — a rigorous system for comparability and scientific integrity.
Systems Medicine Approach — integrated assessment of organ functions.
Longitudinal Data Collection — repeatable, structured examinations create individual health trajectories.
Multimodal Data Integration — clinical, molecular and digital health markers form a complete picture.
Built-in Iteration — continuous monitoring enables ongoing adjustment of interventions.
Evidence-generating Treatment — With consent, treatment insights support research into age-related diseases and the advancement of our protocols.
