NAD+
NAD+ (Nicotinamide Adenine Dinucleotide) is a critical coenzyme found in every living cell. It plays a central role in energy metabolism, DNA repair, and the activation of sirtuins — proteins associated with longevity. NAD+ levels decline significantly with age, and supplementation has been studied for its potential to restore cellular energy, improve mitochondrial function, and slow aging processes.
