Pairing NMN and NR creates a powerful approach to restore NAD+ levels. These dual NAD+ precursors work through different biosynthesis routes - NMN is absorbed via the direct transport pathway, while NR employs riboside kinase enzymes. This NMN NR combination enhances mitochondrial function more effectively than either alone. Increased NAD+ levels support longevity pathways, PARP enzyme function, and cellular health.
