Description
All presented information is based on scientific publications which can be found at the end of product description below.
NAD+ (nicotinamide adenine dinucleotide) is a fundamental coenzyme functioning as a critical electron carrier and substrate for DNA repair, gene expression regulation, and cellular signaling enzymes.
Research Highlights
1. Energy Metabolism โ Essential cofactor in glycolysis, citric acid cycle, and oxidative phosphorylation.
2. Sirtuin Activation โ Obligate substrate for SIRT1-7, controlling deacetylation of histones and proteins.
3. DNA Repair โ PARP enzymes consume NAD+ for poly-ADP-ribosylation during damage repair.
4. Age-Related Decline โ Progressive depletion across tissues correlates with metabolic dysfunction and inflammation.
5. Neuroprotection โ Supplementation may protect against neurodegeneration through enhanced mitochondrial function.

Frequently asked questions
- NAD+ (nicotinamide adenine dinucleotide) is technically a coenzyme (a pyridine nucleotide), not a peptide โ molecular formula CโโHโโNโOโโPโ, MW โ 663.43 g/mol. It is included in the Peptra Labs research catalog because of its central role in metabolism, sirtuin activity, and aging research.
- Each batch is HPLC-verified at โฅ99% purity, with attention to the oxidized (NAD+) vs reduced (NADH) state. The COA confirms identity and form.
- Store lyophilised NAD+ at -20 ยฐC, sealed and protected from light and moisture. NAD+ is hygroscopic and degrades to ADP-ribose under aqueous conditions, especially at neutral or alkaline pH. Reconstitute in slightly acidic buffer for best stability and use promptly.
- NAD+ is used in research on cellular bioenergetics, sirtuin enzyme activity (SIRT1-7), poly-ADP-ribose polymerase (PARP) pathways, redox biology, and aging models. NAD+ levels decline with age in many tissues, motivating extensive aging-research interest.
- NAD+ is sold as a dietary supplement in some markets but is not an FDA-approved drug for any specific indication. Research-grade NAD+ from Peptra Labs is for laboratory research only.
