NMN (Nicotinamide Mononucleotide) and NR (Nicotinamide Riboside) are the two most popular NAD+ precursor supplements. But which one is actually better? Here’s what the science says. How They Work Both NMN and NR are precursors to NAD+, meaning your body converts them into NAD+. The difference is in the conversion pathway: NR pathway: NR → NMN → NAD+ NMN pathway: NMN → NAD+ NMN is one step closer to NAD+, which theoretically makes it more efficient. ...
