In this episode of Daily Value, we look at science of Nicotinamide Mononucleotide (NMN) and Nicotinamide Riboside (NR), two NAD+ precursors gaining traction in longevity research. Both supplements aim to restore NAD+ levels, critical for energy metabolism and cellular repair, yet their distinct pathways and tissue-specific effects suggest considerations for choosing one over the other.
Discussion Points:
-The metabolic pathways of NMN and NR, highlighting how their mechanisms of action influence NAD+ synthesis across tissues.
-Insights from a 2024 study (in rodents - PMID: 38645109) demonstrating the dual effects of NMN: improvements in cardiac and liver function, alongside kidney inflammation linked to toxic metabolite accumulation at high doses.
-Clinical dosing strategies, safety considerations, and how age and tissue-specific needs may guide the choice between NMN and NR.
