The synergistic pairing of NMN and NR creates a powerful approach to increase NAD+ production. These synergistic compounds work through different cellular pathways - nicotinamide riboside utilizes NRK1 and NRK2 enzymes while nicotinamide mononucleotide avoids certain enzymatic limitations. This complementary supplementation promotes optimal mitochondrial function, helping trigger sirtuins and PARP enzymes.
