NAD⁺ Stability: Real-World Shipping & Storage Results
Nicotinamide adenine dinucleotide (NAD+) is a critical coenzyme involved in cellular redox reactions, but its stability in aqueous solutions is influenced by environmental factors such as temperature, pH, and time. This study evaluated the stability of NAD+ (nominal 200 mg/mL) during simulated shipping (short: ~12-15 hours; long: ~3 days) and subsequent storage (room temperature vs. refrigeration) using high-performance liquid chromatography with UV/Vis detection (HPLC-UV/Vis).
