Nicotinamide mononucleotide (” NMN ” and ” β-NMN “) is a nucleotide derived from ribose and nicotinamide .  Like nicotinamide riboside , NMN is a derivative of niacin , and humans have enzymes that can be used to generate nicotinamide adenine dinucleotide (NADH). 
Because NADH is a cofactor for processes inside mitochondria , for sirtuins , and for PARP , NMN has been studied and hyped as a potential neuroprotective and anti-aging agent.
