Nicotinamide Mononucleotide (NMN) is one of the naturally occurring molecules. It is also classified as bioactive nucleotide.
There has been quite a controversy surrounding nicotinamide mononucleotide (NMN) with U.S. federal regulators in recent years. The Food and Drug Administration (FDA) prohibits marketing NMN as a dietary supplement in the United States. Since NMN is banned in the United States, several manufacturers market this supplement by claiming it has anti-aging properties.
