Nicotinamide mononucleotide (NMN) is a precursor molecule for the biosynthesis of NAD+, a coenzyme that participates in the production of cellular energy and DNA repair. *

​

Nicotinamide mononucleotide is present in various types of food, including broccoli, avocado, and beef, but it is also an intermediate compound in the NAD+ salvage pathway, the recycling of nicotinamide into NAD+.*

​

NAD+ acts as a cellular "sensor" to mediate energy-generating pathways and activate NAD+-consuming enzymes such as sirtuins and poly ADP-ribose polymerases (PARP). *

​

NAD+ depletion, which occurs with age, has been implicated in the progression of multiple age-related conditions. NMN helps maintain cellular levels of NAD+. Boosting NAD+ levels through precursors has proven to have the potential to support longevity across multiple animal models. *
