NMN 101: What You Need to Know (2024)
What’s NMN? NMN stands for nicotinamide mononucleotide , a molecule naturally occurring in all life forms. At the molecular level, it is a ribo-nucleotide, which is a basic structural unit of the nucleic acid RNA. Structurally, the molecule is composed of a nicotinamide group, a ribose and a phosphate group (Figure 1). NMN is the direct precursor of the essential molecule nicotinamide adenine dinucleotide (NAD+) and is considered a key component to increase NAD+ levels in cells. What is Nicotinamide Adenine Dinucleotide (NAD+)? NAD+ is an essential coenzyme required for life and cellular functions. Enzymes are catalysts that make biochemical reactions possible. Coenzymes are ‘helper’ molecules that enzymes need in order to function. What Does NAD+ Do? NAD+ is the most abundant molecule in the body besides water, and without i...
