Humidity or water can have negative effects on NMN and result in the degradation of NMN into NAD+. This fact is not disputed and thus NMN powder should be stored in a dry place in a resealable container. | Humidity or water can have negative effects on NMN and result in the degradation of NMN into NAD+.

In addition, scientists have tested NMN powders and found that these do not need to be kept in the refrigerator or freezer. The purity at 1 year when stored in a plastic bottle at room temperature was found to be 99.8%. | In addition, scientists have tested NMN powders and found that these do not need to be kept in the refrigerator or freezer. The purity at 1 year when stored in a plastic bottle at room temperature was found to be 99.8%. Also a NMN manufacturer published NMN stability results when putting NMN into double pharmaceutical polyethylene bags. After 6 month under condition of 40℃ and 75% relative humidity the samples had > 99% purity.<ref>https://age-science.com/wp-content/uploads/2021/08/Age-Science-Research-on-NMN-stability-6-month.pdf</ref> | ||
However, it is advised if storing for the long-term (> 3 months), NMN supplements should be kept in the refrigerator to ensure its stability. | However, it is advised if storing for the long-term (> 3 months), NMN supplements should be kept in the refrigerator to ensure its stability. |
