NAD+ · Stability & Shelf Life
Stability & Shelf Life
Research compounds degrade over time, and how fast depends on how they are stored. This reference covers what degrades NAD+, and how its dry (lyophilized) stability window compares to its reconstituted window. It is laboratory reference guidance, not a use protocol. For research use only. Not for human consumption, diagnostic, or therapeutic use.
What degrades the compound
The main degradation drivers for NAD+ are heat, light, moisture, oxidation, and (once in solution) repeated freeze-thaw cycling. Each can alter the molecule in ways that change analytical readouts, which is why the documented storage condition is −20°C, desiccated, strictly light-protected.

Dry vs reconstituted stability
Lyophilized NAD+ stored cold, dry, and dark has the longest stability window. Once reconstituted, its window shortens substantially: a liquid solution is more exposed to the stressors above, so prepared material is typically refrigerated and used within a limited period.
This dry-versus-liquid difference is why labs reconstitute only what a study requires.
Best practice for integrity
To preserve integrity: minimize freeze-thaw by aliquoting before freezing, keep the material light-protected, and avoid warming the vial unnecessarily. Documenting preparation and storage dates makes any stability question traceable.

Questions, answered
What is the shelf life of NAD+?
Lyophilized NAD+ stored at −20°C, desiccated, strictly light-protected has the longest window; reconstituted material is shorter-lived and refrigerated. Exact figures depend on storage and are documented per batch.
What degrades NAD+ fastest?
Heat, light, moisture, and repeated freeze-thaw cycles are the primary stressors.
Does reconstituting shorten the shelf life?
Yes. In solution NAD+ is more exposed to degradation and is used within a shorter, refrigerated window than the dry powder.
Is this stability data a use recommendation?
No. It is laboratory storage reference. For research use only. Not for human consumption, diagnostic, or therapeutic use.
