Tip #1: Store NMN in a Cool, Dry, Dark Place
When exposed to heat, water, or light, NMN degrades into nicotinic acid or nicotinamide. To avoid potential issues, keep NMN in a dry, sealed, opaque container. The bag your NMN comes in is great for this. Also, be sure to store NMN in a cool climate. 76 degrees Fahrenheit (24 Degrees Celsius) or cooler is ideal. Temperatures higher than this could cause your NMN to degrade. Many people keep their NMN in the original NMN Direct packaging, and place the entire package in their refrigerator (though this is not recommended if you have children).
