NAD+ (nicotinamide adenine dinucleotide) is a vital coenzyme found in all living cells, essential for energy production, DNA repair, and cellular longevity. Boosting NAD+ levels—which naturally decline with age—may improve mitochondrial function, stamina, enhance cognitive health, reduce inflammation, boost energy, and slow the aging process. NAD+ is a critical cofactor that enhances mitochondrial function, serving as the primary fuel for the intracellular energy powerhouses that convert micronutrients into ATP and support DNA repair.
