Amazing discussion topic! I've been looking into these NAD+ precursors for months now and what I've found is that combining both NMN and NR can dramatically restore NAD+ levels through multiple mechanisms - NMN operates via the direct transport pathway while NR gets converted via kinase enzymes and both enhance mitochondrial function plus longevity pathways which is crucial for healthy aging especially since NAD+ levels drop as we age starts in our 30s and combining them with quercetin CD38 inhibitor and methylation cofactors has improved my energy levels and cognitive health significantly - I'm currently using moderate doses of each in my longevity protocol
