NAD+ Longevity Assessment & Optimisation

Precision NAD+ level testing to assess cellular energy and DNA repair capacity, with personalised supplementation strategies including NMN to restore youthful NAD+ levels and support longevity.

NAD+ (nicotinamide adenine dinucleotide) is one of the most important molecules in the human body for healthy ageing. It is essential for mitochondrial energy production (ATP synthesis via the electron transport chain), DNA damage repair (as a substrate for PARP enzymes), regulation of circadian rhythms via SIRT1 and other sirtuins, and cellular stress response pathways. NAD+ levels naturally decline by approximately 50% between the ages of 40 and 60, and this decline is now recognised as a major contributor to the hallmarks of ageing: impaired mitochondrial function, accumulating DNA damage, reduced metabolic efficiency, and declining cellular regeneration. Chi Longevity's NAD+ programme begins with precise blood-based measurement of NAD+ levels — a test that reveals your current cellular energy status and identifies whether NAD+ depletion is a meaningful factor in your individual ageing trajectory. This measurement is a standard component of the Vital Start and all higher-tier flagship programmes, and is also available as part of targeted longevity panels. Results are interpreted in the context of your broader metabolic and biological age assessment. Where NAD+ depletion is identified, Chi Longevity's clinical team provides personalised recommendations for NAD+ restoration. The clinic offers NMN (nicotinamide mononucleotide) supplementation — a direct NAD+ precursor with strong preclinical and emerging human evidence for NAD+ restoration and longevity benefits. Dosing, formulation, and duration are tailored to your specific results and lifestyle context, avoiding the one-size-fits-all supplementation approaches common in wellness retail. Ongoing monitoring of NAD+ levels can be incorporated into follow-up assessments (including the Pinnacle six-month re-test) to measure the biological response to supplementation and lifestyle interventions, providing objective evidence of progress rather than relying on subjective symptom reporting alone.
