——FAQ——

1. 1.What are the main applications of NAD+?

   
   

   NAD+ (Nicotinamide Adenine Dinucleotide) is an important coenzyme widely used in anti-aging research, cellular metabolism study, nutritional supplement raw material and biochemical laboratory testing. It participates in human energy metabolism and cellular repair-related preclinical research, popular as raw material for health product formulation.

   
   
2. 2.How to store NAD+ to keep its activity stable?
   NAD+ is sensitive to temperature and moisture. Short-term storage needs sealed preservation at 2-8°C in dry and dark environment; long-term storage should be kept below -20°C away from damp and repeated temperature changes to avoid activity decline.
