This topic is lockedAfter spending considerable time researching NAD+ precursors, I've become increasingly aware that how we store these supplements matters almost as much as the quality we buy.
The Science of Degradation
NAD+ precursors like NMN and NR are hygroscopic—they absorb moisture from the air. Once moisture gets in, the degradation process accelerates significantly. Temperature fluctuations compound this problem, as thermal cycling can cause condensation inside the container.
Key Storage Recommendations:
- Keep supplements in a cool, dry place (ideally below 25°C/77°F)
- Refrigeration can extend shelf life, but allow the container to reach room temperature before opening
- Use desiccant packets in your storage container
- Avoid bathroom storage—humidity is too variable
- Purchase from suppliers who ship with cold packs in summer months
Signs of Degradation
Watch for clumping, color changes (yellowing), or unusual odors. Quality suppliers will provide third-party testing results and proper storage guidance.
I've found some helpful resources on NAD+ storage best practices at https://www.glunovab...s-storage-guide that cover the technical details.
Has anyone here experimented with different storage methods? I'm curious whether frozen storage provides any significant advantage over refrigeration for long-term stability.
