    What our customers says:

    "I used to feel totally overwhelmed trying every supplement, diet trick, and gadget out there. After getting my biomarker analyed, I redesigned everything with help of Teemu & team. I stopped taking 6 unnecessay supplements (saving over 200€ monthly) and finally implemented the exact diet and lifestyle changes that mattered for me. Now I have way more energy, I recover faster, and I feel confident that I'm actually adding healthy years." - Jan B., Verified Customer

      Swiss Lab Accuracy

      All samples are analyzed in accredited Swiss laboratories in Geneva - partners of leading longevity clinics and elite athletes worldwide. Advanced mass spectrometry measures thousands of molecules from just a few drops of blood for unparalleled precision and consistency. Our Longevity NAD Test offers a clear picture of your body's cellular health and energy potential.

      Understanding NAD and its importance

      NAD (Nicotinamide Adenine Dinucleotide) is a vital biomarker involved in many cellular processes, making it a key player in overall health and longevity. This coenzyme is crucial for energy production, DNA repair, and cellular signaling. It acts as a mediator in metabolic pathways, enabling the conversion of nutrients into ATP (adenosine triphosphate), the primary energy currency of cells.

      Additionally, NAD serves as an essential cofactor for enzymes involved in DNA repair, gene expression, and response to oxidative stress. Optimal NAD levels support cellular resilience, boost energy metabolism, and enhance overall wellbeing.

       

       

      FAQ

      • How do I take the test?
