Cellular Rejuvenation: The Truth About NAD+ Coenzymes and Longevity
Executive Summary & The Mitochondrial Decline The relentless march of biological time is fundamentally a crisis of systemic energy. At the absolute core of cellular senescence, cognitive decline, cardiovascular stiffening, and metabolic decay lies a single, master bottleneck: the progressive, age-dependent depletion of Nicotinamide Adenine Dinucleotide ($\text{NAD}^+$). This essential coenzyme, present in every living cell, … Read more
