NAD+ precursors like nicotinamide mononucleotide (NMN) and nicotinamide riboside (NR) increase NAD+ by providing substrate for the salvage pathway, while 5-Amino-1MQ increases NAD+ by inhibiting NNMT, the enzyme that removes nicotinamide from circulation
The cycling protocols commonly recommended are partly based on this theoretical concern, though actual tolerance development has not been documented
Both methods can help increase your B12 levels, but they differ significantly in delivery and how quickly you experience the benefits
Informal reports sometimes describe body-composition changes after 4 to 6 weeks, but these reports are not controlled evidence
5-Amino-1MQ increases NAD+ levels by lowering NNMT
Some people need monthly injections, while others may space them further apart once levels normalize
