Storage Instructions
Proper storage is critical to preserve NAD+ stability and potency.
- Lyophilized (Unopened): Store at −20 °C (−4 °F) or below (ideally −80 °C for multi‑year storage) in a dry, dark environment[6]. Minimize moisture exposure as NAD+ powder is hygroscopic.
- Reconstituted Solution: Refrigerate at 2–8 °C (35.6–46.4 °F) and use within approximately 14 days[7]. Keep protected from light (UV exposure degrades NAD+).
- Avoid Freeze–Thaw Cycles: Do not repeatedly freeze and thaw reconstituted NAD+ solution, as this reduces potency.
- Inspection: Before each use, inspect the solution for clarity. A fresh NAD+ solution should be clear and colorless. Discard if discoloration, cloudiness, or precipitate develops.
