NAD+ and Cellular Energy
NAD+ is one of the most studied molecules in cellular-energy research, and it is not a peptide. This guide covers what it is, how it works, and where it fits in a considered regimen.
The Short Answer
- NAD+ is a coenzyme, not a peptide, and is supplied by Polaris Research in a 1000mg vial.
- The 1000mg format gives NAD+ one of the lowest per-milligram figures in the catalogue.
- NMN is a precursor that sits one step upstream of NAD+ on the same pathway.
- Polaris Research supplies NAD+ and does not stock NMN.
What NAD+ actually is
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme, a molecule the cell uses constantly, not a peptide or a hormone. It is central to redox chemistry: the everyday machinery by which cells carry electrons, generate ATP, and manage the energy flow that keeps them alive. It also participates in the signalling pathways that govern cellular repair.
NAD+ levels decline with age, which is one reason the molecule is studied in longevity and cellular-energy research, often alongside peptides like MOTS-c and SS-31 that speak to the mitochondria directly.
How it differs from a peptide
A peptide is a short chain of amino acids that carries a message between cells. A coenzyme like NAD+ is a helper molecule that enables enzymes to do their work. The distinction matters because it changes how the compound is studied, stored, and handled. NAD+ is a larger molecule (the 1000mg vial reflects that), and it is reconstituted and stored with the same gentle handling as a peptide.
Both, though, are studied for how they support the cellular-energy layer that sits beneath the more visible outcomes people track.
Where it fits in a regimen
NAD+ sits in the cellular-energy and immunity family, studied alongside MOTS-c and SS-31 (the mitochondria-targeting peptides) and the immune-modulating compounds. It is the layer people tend to reach for once the foundations, sleep, protein, movement, are already steady, because cellular-energy signalling is what gives those baselines something to amplify.
Every 1000mg vial ships with an independently verified batch certificate (≥98% purity) and Free Express Delivery Australia-wide. Follow the supplied handling notes after reconstitution, store reconstituted solution refrigerated, and never refreeze it.
Frequently Asked
Is NAD+ a peptide?
No. NAD+ is a coenzyme, specifically a dinucleotide, so it sits outside the peptide families even though it is stocked alongside them. That distinction is why it is described as a coenzyme throughout this catalogue.
What is the difference between NAD+ and NMN?
Position on the same pathway. NMN is a precursor the body converts; NAD+ is the coenzyme itself. Polaris Research supplies NAD+ and does not stock NMN.
Why is the NAD+ vial 1000mg?
It is supplied at a far larger mass than the peptide vials in the range, which makes the per-milligram figure the one worth reading rather than the headline per-vial price.
