Using together NMN and NR generates a synergistic approach to increase NAD+ levels. These dual NAD+ precursors work through separate routes - nicotinamide riboside utilizes cellular kinases while nicotinamide mononucleotide avoids certain conversion steps. This synergistic effect maximizes NAD+ biosynthesis for improved mitochondrial function. Increased NAD+ levels promote longevity pathways, genomic maintenance, and healthy aging.
