NAD+ is one of the most researched molecules in the longevity field, yet it is not a peptide. In this guide we explain, research-only, what NAD+ is, why it is so central to ageing research, and how it compares to other longevity research peptides.
NAD+ is a co-enzyme present in every cell, essential for energy metabolism. Research has described its concentration declining with age, making NAD+ a central research subject in longevity research. No proven intervention in humans, research-grade material only.
What is NAD+?
NAD+ (nicotinamide adenine dinucleotide) is a co-enzyme present in every living cell, playing a key role in transferring electrons during energy metabolism. It is not a peptide — not a chain of amino acids — but a nucleotide co-enzyme. Peptide Lab offers it within the same longevity category because the research field strongly overlaps with peptides such as Epithalon and SS-31.
Why is NAD+ so central to longevity research?
Research has described cellular NAD+ concentration declining with age, alongside decreasing activity of NAD+-dependent enzymes such as sirtuins and PARPs. That correlation is exactly why NAD+ recurs so often in ageing research. This concerns preclinical and physiological research and is no proof of effect or usage advice.
NAD+ versus NMN and NR
NMN and NR are not NAD+ itself, but precursors — molecules the body can convert into NAD+ via different pathways. Peptide Lab offers NAD+ itself as research-grade material, not the precursors. Browse the broader anti-ageing & longevity category for related research molecules such as SS-31, which targets mitochondria specifically.
Purity and documentation
Reproducible longevity research requires material with verified purity and full traceability. Every batch of NAD+ at Peptide Lab is tested by Janoshik Analytical, with a public certificate per lot number. Read more about our approach on the science page.
This information is general and intended solely for a research context. Peptide Lab supplies NAD+ for laboratory and research purposes only. Not for human or animal consumption, not a medicine and not medical advice.
Frequently asked questions about NAD+
What is NAD+?
NAD+ (nicotinamide adenine dinucleotide) is a co-enzyme present in every living cell that plays a central role in energy metabolism and cellular repair processes. It is not a peptide, but is often offered in the same category due to its link to longevity research.
Why does NAD+ decline with age, and why is that relevant to research?
Research has described a declining NAD+ concentration with age, linked to decreasing activity of NAD+-dependent enzymes such as sirtuins. That correlation makes NAD+ a recurring research subject within longevity research, without implying a proven intervention in humans.
What is the difference between NAD+ and NMN or NR?
NMN (nicotinamide mononucleotide) and NR (nicotinamide riboside) are precursors — molecules the body can convert into NAD+. Peptide Lab offers NAD+ itself, solely as research-grade material.
Is NAD+ from Peptide Lab pure?
Yes, NAD+ is lab-verified for purity by HPLC and mass spectrometry, with a public Janoshik certificate per batch. For research purposes only.
