What is NAD+? A Cellular Energy Peptide Breakdown
Compound Spotlight
NAD+ is one of the most-discussed molecules in longevity research, referenced constantly in the broader conversation around aging and cellular health. This article covers what it actually is and what the research says.
Quick summary
- NAD+ is a coenzyme, not a peptide, though it is commonly researched alongside peptide compounds.
- Required for hundreds of enzymatic reactions, most notably mitochondrial ATP production.
- Studied for its role in DNA repair and sirtuin activation, both central to aging research.
- NAD+ levels are well-documented to decline with age, which drives most current research interest.
What is NAD+?
NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme found in every living cell, playing a central role in converting nutrients into cellular energy. Unlike many compounds discussed in this space, NAD+ is not a peptide but a small molecule coenzyme, though it is frequently sold and researched alongside peptide compounds.
What it is studied for
- Cellular energy metabolism and mitochondrial function
- DNA repair pathway research
- Sirtuin activation, a family of proteins linked to aging research
- Age-related decline in NAD+ levels and its downstream effects
How it is thought to work
NAD+ is a required cofactor for hundreds of enzymatic reactions, most notably in the mitochondrial pathways that generate ATP, the cell’s primary energy currency. Research has also focused on its role in activating sirtuins and PARPs, enzyme families connected to DNA repair and cellular stress response, both of which are central to current aging research.
Research history
NAD+ was first identified over a century ago, long before its role in cellular aging became a research focus. Early biochemistry research established its function as a cofactor in metabolism, particularly in the electron transport chain that generates ATP. For decades it was treated primarily as a foundational metabolic molecule rather than a subject of standalone research interest.
That changed as sirtuins, a family of proteins dependent on NAD+ for activity, were linked to lifespan extension in yeast and animal models starting in the late 1990s and early 2000s. This connection reframed NAD+ from a background metabolic molecule into a central variable in aging research, driving the current wave of interest in restoring NAD+ levels as they decline with age.
Where the research stands
NAD+ levels are well-documented to decline with age, which is the primary driver of research interest. Studies span decades of foundational biochemistry combined with a newer wave of research specifically examining whether restoring NAD+ levels affects markers of cellular aging.

Frequently asked questions
Is NAD+ a peptide?
No. NAD+ is a coenzyme, not a peptide. It is grouped alongside peptide compounds because it is commonly studied and sold within the same research category, particularly in longevity research.
How do I know what is actually in the vial?
Every lot we sell has a published Certificate of Analysis from an independent, third-party lab, confirming both identity and purity. You can look up any lot number directly on our site.
