Certificate of Analysis
Scientific Overview
Nicotinamide adenine dinucleotide (NAD+) is a coenzyme found in all living cells. It serves as an electron carrier in metabolic redox reactions and is a required co-substrate for enzymes including sirtuins, PARPs, and CD38/CD157 ectoenzymes.

Research & Clinical Studies
NAD+ and Sirtuin Biochemistry
NAD+ is a required co-substrate for sirtuin enzymes (SIRT1-7), which catalyze NAD+-dependent deacetylation reactions. Biochemical studies have characterized the stoichiometry of NAD+ consumption during sirtuin-mediated deacetylation.
NAD+ Biosynthesis Pathways
Three biosynthetic pathways for NAD+ have been characterized: the de novo pathway from tryptophan, the Preiss-Handler pathway from nicotinic acid, and the salvage pathway from nicotinamide.

Frequently Asked Questions
What is the purity of NAD+?
Our NAD+ is verified at 98.5% purity through independent third-party HPLC analysis. Each production batch undergoes rigorous quality testing, and a Certificate of Analysis (COA) is available for review in our COA Library.
How should I store this peptide?
Store in a cool, dry place at -20°C. Protect from light and humidity. Hygroscopic — keep tightly sealed. Once reconstituted, solutions should be used promptly or stored frozen to maintain stability. Avoid repeated freeze-thaw cycles for best results.
Do you provide Certificates of Analysis?
Yes — every batch we produce is independently tested via HPLC and mass spectrometry to confirm identity and purity. COAs for all current batches are publicly accessible through our COA Library.
How is the product shipped?
All orders ship within 24 hours of purchase via USPS Priority Mail. Products are carefully sealed and packaged to ensure stability during transit. Orders over $150 qualify for free shipping. If you receive a damaged, defective, or incorrect product, please contact our support team with photos within 48 hours of delivery.
