Proper storage is crucial for maintaining NMN/NR supplement potency. Here’s how to store them correctly.

Why Storage Matters

NMN and NR are sensitive to:

  • Heat — Degrades the molecules
  • Moisture — Causes breakdown
  • Light — UV light degrades NAD+ precursors
  • Oxygen — Oxidation reduces potency
