Combining NMN and NR provides a synergistic approach to increase NAD+ levels. These dual anti-aging supplements work through separate pathways in NAD+ restoration, with nicotinamide riboside supplement utilizing NRK1 NRK2 enzymes while NMN skips this enzymatic process. This dual approach maximizes intracellular NAD+ availability for longevity pathways, cellular energy, and PARP enzymes.
