How to Store NAD+: Temperature, Shelf Life & Handling
Storage requirements for NAD+ follow from what the molecule actually is — dinucleotide coenzyme — not a peptide. The conditions below reflect that chemistry rather than generic peptide guidance.
In plain English
Freezer, rigorously dry, and use mixed solution within one to two weeks. This powder pulls moisture out of the air more aggressively than anything else here. Open a cold vial and water condenses straight onto the contents within minutes.
What NAD+ actually is
NAD+ is not a peptide, and that single fact governs everything about handling it. It is a coenzyme — think of it as a rechargeable battery that shuttles energy around inside cells. It is present in every living cell, was first identified in 1906, and almost every peptide habit is wrong for it.

Storage conditions for NAD+
Why these conditions, specifically
Do not apply peptide-handling intuitions to NAD+. It is a nucleotide, its degradation chemistry is hydrolytic rather than oxidative or proteolytic, and its pH sensitivity runs the opposite direction to several peptides in this catalogue.
The main route to be aware of: alkaline hydrolysis — NAD+ degrades rapidly above neutral pH. This is the single most important handling fact about the compound.

Aliquot immediately after reconstitution. NAD+ solutions tolerate freezing but each thaw restarts the hydrolytic clock.
What NAD+ is studied for
Sirtuins consume NAD+ as a co-substrate, which links cellular NAD+ availability directly to their activity.
Its canonical role as the central redox carrier of cellular respiration.
PARP enzymes consume NAD+ during DNA damage response, a heavily studied competing demand.
A major driver of current research interest: measured NAD+ levels fall with age across tissues in animal models.
