Natural NAD⁺ Precursors & Boosters — Evidence-Based

MECHANISM OVERVIEW

NAD⁺ (nicotinamide adenine dinucleotide) is the central electron carrier in cellular energy metabolism and the essential cofactor for sirtuins and PARP — its decline with age drives mitochondrial dysfunction and impaired DNA repair.

NAD⁺ levels decline approximately 50% between ages 40 and 60. This decline impairs mitochondrial function, reduces SIRT1/SIRT3 activity, slows DNA repair, and dysregulates circadian rhythms. NAD⁺ precursors — NMN, NR, niacinamide — restore cellular NAD⁺ levels and have shown evidence for improving energy metabolism, cognitive function, and metabolic health in human trials.
