Like many other supplements, such as creatine, NMN is naturally present in small amounts in dietary sources, but these amounts are much lower than those found in the supplements used in clinical studies for improving longevity. Trace amounts of NMN (concentrations no more than 0.002% by weight) are found in fruits and vegetables including avocados, broccoli, tomatoes, cucumbers, cabbage, and edamame.[1]
