Using together NMN and NR creates a potent combination for restoring NAD+ levels. These two precursors work through different pathways in mitochondrial function, with NR utilizing the kinase pathway while NMN employs the mononucleotide pathway. This dual approach maximizes mitochondrial energy more effectively than either supplement alone. Boosted NAD+ production support SIRT1 function, DNA repair mechanisms, and healthy aging processes.
