Why Do NAD+ Levels Decline With Age? The Process Behind the Drop

Why NAD+ levels decline with age is an important question in longevity science because NAD+ plays a central role in cellular energy production and repair. In this video, we explain why NAD+ tends to fall over time, what may drive that decline, and why it matters for aging, metabolism, healthspan, and healthy aging. Full article: https://longevityinsights.co.uk/why-do-nad-levels-decline-with-age/ In aging research, NAD+ decline is often linked to increased cellular stress, higher demand for DNA repair, mitochondrial dysfunction, and changes in metabolic regulation over time. Researchers study NAD+ alongside biomarkers of biological aging, inflammation, and energy metabolism because lower NAD+ availability may affect how well cells produce energy and maintain resilience. Understanding why NAD+ levels decline with age can help explain why this molecule has become such a major focus in longevity science and healthy aging research.
