NAD+ Research Australia: Overview
For laboratory research use only. Not for human use. Research use only.
NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme found in all living cells that plays a central role in energy metabolism, DNA repair, and cellular signalling. Research interest in NAD+ has surged in recent years due to its apparent role in longevity pathways, particularly through its interaction with sirtuins and PARP enzymes. This guide covers the research landscape for Australian researchers.
What is NAD+?
NAD+ is a dinucleotide coenzyme consisting of two nucleotides joined through their phosphate groups. It exists in oxidised (NAD+) and reduced (NADH) forms and is essential for the electron transport chain in mitochondria. NAD+ levels decline with age in most tissues, which has prompted significant research into NAD+ precursors and direct NAD+ supplementation.
NAD+ is not a peptide in the strict sense but is frequently studied alongside peptides in longevity and metabolic research. PeptideIQ supplies research-grade NAD+ for laboratory research use only.
Sirtuin and Longevity Research
Sirtuins (SIRT1-7) are a family of NAD+-dependent deacetylases that have been extensively studied in the context of longevity and metabolic regulation. Research in model organisms including C. elegans, Drosophila, and mice has observed apparent lifespan extension with increased sirtuin activity, which is dependent on adequate NAD+ availability.
A landmark 2013 study by David Sinclair's laboratory at Harvard demonstrated apparent restoration of mitochondrial function in aged mice following NAD+ precursor supplementation. These findings have driven substantial research interest in NAD+ biology and its potential role in age-related decline.
PARP and DNA Repair Research
PARP (Poly ADP-ribose polymerase) enzymes are major consumers of NAD+ in cells and play a critical role in DNA damage repair. Research has examined the relationship between NAD+ availability, PARP activity, and DNA repair capacity, with some studies suggesting that declining NAD+ levels with age may impair DNA repair efficiency.
This research has implications for understanding age-related genomic instability and has prompted investigation into whether maintaining NAD+ levels through supplementation or precursor administration can support DNA repair capacity in preclinical models.

Frequently Asked Questions
What is the difference between NAD+ and NMN?
NMN (Nicotinamide Mononucleotide) is a precursor to NAD+ — the body converts NMN to NAD+. PeptideIQ supplies direct NAD+ for research applications where the final coenzyme is required rather than a precursor.
Is NAD+ available in Australia for research?
Yes. PeptideIQ supplies research-grade NAD+ in Australia for laboratory research use only. It is not approved for human therapeutic use.
