NAD+: The Coenzyme in Longevity Research Explained
NAD+ is not strictly a peptide but a coenzyme, and its age-related decline is studied as one contributor among several to cellular changes. Research into supplementation is ongoing and findings remain preliminary.

NAD+ (Nicotinamide Adenine Dinucleotide) is not strictly a peptide — it is a coenzyme. But it is one of the most prescribed injectable compounds in longevity medicine, and its decline with age is one of the most directly documented contributors to the cellular dysfunction we experience as getting older.
What NAD+ Does
NAD+ is required for over 500 enzymatic reactions, with particular importance in three areas: mitochondrial energy metabolism (the conversion of nutrients into ATP via the electron transport chain), DNA repair (as a substrate for PARP enzymes that repair single-strand DNA breaks), and sirtuin activation (a family of proteins that regulate gene expression, inflammation, and cellular stress responses). When NAD+ is abundant, these systems work efficiently. When it depletes, they slow.
Why It Declines and How It Is Studied
By the time most people reach their fifties, tissue NAD+ levels are estimated to have fallen by 50% or more from youthful levels. Oral precursors, NMN and NR, are studied for raising NAD+ by providing biosynthetic substrate, but their bioavailability and conversion efficiency vary considerably between individuals. Injectable NAD+ delivers the coenzyme directly into circulation, bypassing the conversion pathway, although how this translates into cellular availability is still being researched.
- Prescribed in several formats, including injectable and nasal spray
- Central to mitochondrial energy production, DNA repair, and sirtuin activation
- Levels are estimated to fall by up to 50% between youth and midlife
- Injectable form enters circulation directly, bypassing oral conversion
