NAD+ for Laboratory Research: Identity, Stability and a Buying Checklist

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every living cell and one of the most referenced compounds in cellular energy and longevity-focused laboratory research. It is often listed next to peptides, but it is not one, and it behaves differently in storage. This guide covers what it is, why handling matters and what to check before buying.

Key Facts

• Type: Coenzyme (a dinucleotide); not a peptide
• Molecular formula: C21H27N7O14P2
• Molecular mass: about 663.4 Da
• CAS number: 53-84-9
• Supplied as: lyophilised powder in a sealed vial

What NAD+ Is

NAD+ is a dinucleotide: an adenine nucleotide and a nicotinamide nucleotide joined through their phosphate groups. Its molecular weight is about 663.4 Da. In the cell it cycles between an oxidised form (NAD+) and a reduced form (NADH) and carries electrons between metabolic reactions.

What the Research Literature Covers

• Redox reactions in cellular energy metabolism
• NAD+ as a substrate for sirtuins, PARPs and CD38
• Changes in NAD+ levels in ageing models
• Mitochondrial function in cell and animal models

These are laboratory findings. CellMind supplies NAD+ strictly for research purposes, not for human consumption.

Why Stability Matters More Than Usual

NAD+ is hygroscopic: it takes up moisture from the air. In solution it degrades faster with heat, light and alkaline pH. For this reason the form it ships in (lyophilised, sealed) and the way it is stored after opening affect the result as much as the purity figure on the report.

How Identity and Purity Are Confirmed

HPLC shows the share of NAD+ in the material and reveals degradation products such as nicotinamide. Both identity and purity belong on a batch-specific Certificate of Analysis. For how to read one, see What Is a CoA and Why Is It the Only Real Proof of Peptide Purity.

Checklist Before You Buy NAD+

• A CoA for the specific batch
• HPLC purity stated as a number, above 99%
• Lyophilised powder in a sealed vial
• The amount per vial stated clearly (500 mg)
• A batch number on the vial that matches the report

Common Questions About NAD+

Is NAD+ a peptide?

No. It is a dinucleotide coenzyme built from two nucleotides, not from amino acids. It is listed next to peptides only because it is used in the same kind of laboratory work.

What is the difference between NAD+ and NADH?

NAD+ is the oxidised form and NADH the reduced form of the same coenzyme. NADH carries two more electrons and one more hydrogen; the two are told apart by HPLC and by their UV absorption.

Storage and Handling

Keep lyophilised vials in a cool, dark place. Once reconstituted, the solution should be refrigerated and used within the planned research window. Avoid repeated temperature changes: they are the most common cause of degradation that nobody notices until results stop matching.
