Combining both NAD+ precursors creates a complementary approach for boosting NAD+ naturally. These two precursors work through different pathways in NAD+ biosynthesis, with NR activating the kinase pathway while NMN leverages the Slc12a8 transporter. This synergistic pairing maximizes mitochondrial energy more effectively than individual compounds. Boosted NAD+ production support sirtuin activation, PARP enzyme activity, and anti-aging benefits.
