Full answer
NAD+ is an essential cofactor for energy metabolism, DNA repair, and sirtuin signaling. Levels decline with age and rise transiently with NAD+ or precursor (NR, NMN) administration. IV NAD+ achieves higher acute exposure than oral precursors. Within oMeds review, NAD+ therapy is positioned within longevity and recovery pathways under provider direction, with patient counseling on the still-evolving outcome evidence and the gap between mechanistic plausibility and durable clinical endpoints.
