Nicotinamide mononucleotide (NMN) is a nucleotide that is most recognized for its role as an intermediate of nicotinamide adenine dinucleotide (NAD+) biosynthesis.
NMN has been studied to keep cells healthy as a person ages. The combination of NR and Resveratrol helps produce NAD+, which promotes healthy DNA cell structure. This is critical for healthy aging. NAD and its precursors have likely been discussed more than any other longevity molecules, at least in the last year. We know that NAD levels decline as we age, and this may be one of the central mechanisms behind why we age. Nicotinamide riboside (NR), a precursor of NAD, has been studied to promote longevity in many different organisms. It works by contributing to promoting DNA repair, modulating immune-cell signaling, inducing energy-intensive enzymes (PARPS, CD38), etc., supporting energy production, and most importantly activating sirtuins.
