What NAD+ is
NAD+ is a dinucleotide coenzyme present in every living cell, acting as an electron carrier in redox reactions and as a substrate for sirtuins and PARP enzymes. Cellular NAD+ concentrations decline with age, which underpins much of the current research interest.
UK Peptide supplies NAD+ as a 500 mg lyophilised vial verified to 99%+ purity.
What the literature examines
Research focuses on mitochondrial energy metabolism, sirtuin-dependent signalling, DNA-repair enzyme activity and NAD+ precursor pathways such as NMN and NR.
Handling
NAD+ is hygroscopic and light-sensitive. Store lyophilised at -20°C protected from light and moisture; keep solutions cold, protected from light, and use promptly.
