NAD+
Nicotinamide Adenine Dinucleotide — a central cellular coenzyme studied for its role in metabolism and aging biology.
Overview
NAD+ is a coenzyme found in every living cell, central to energy metabolism and hundreds of enzymatic reactions. Research interest in NAD+ administration has grown substantially over the past decade following studies linking declining cellular NAD+ levels to aging processes.
Mechanism of Action
NAD+ serves as an essential cofactor for sirtuins — proteins linked to cellular stress resistance and longevity pathways — and for PARP enzymes involved in DNA repair. Research has examined whether restoring or elevating NAD+ levels can support mitochondrial function and metabolic signaling that naturally declines with age.

Safety & Handling
NAD+ should be handled only by qualified personnel in a laboratory setting, stored and reconstituted per its Certificate of Analysis, and kept refrigerated once reconstituted. It is not evaluated or approved by the FDA for any human or veterinary use.
Frequently Asked Questions
Is NAD+ a peptide?
No — NAD+ is a coenzyme, a small organic molecule, not a chain of amino acids. It’s grouped in this library alongside peptides because it’s studied in the same longevity/metabolic research space.
Is NAD+ legal to purchase?
It’s legal to sell and purchase as a research chemical for laboratory use in the U.S. It is not approved by the FDA as a drug or supplement for human consumption in this form.
How should NAD+ be stored?
Keep refrigerated or frozen and protected from light. Once reconstituted, keep refrigerated and use within the timeframe indicated on the Certificate of Analysis.
Is this page medical advice?
No. This page summarizes published literature for research and educational context only. It does not recommend a dose, protocol, or use in humans or animals outside a laboratory setting.
