Nicotinamide mononucleotide (" NMN ", " NAMN ", and " β-NMN ") is a nucleotide derived from ribose and nicotinamide . Like nicotinamide riboside (NR) , NMN is a derivative of niacin NMN is a precursor to NAD+ , or nicotinamide adenine dinucleotide, meaning it becomes NAD+ through a series of chemical transformations. NAD+ is a critical compound found in every cell of your body, but levels of NAD+ naturally fall with age, making it — and NMN, as a result — crucial. NAD+ is vital to cellular metabolism, turning nutrients into cellular energy, and it also activates sirtuins, a set of proteins that regulate cellular health. We all get NAD+ in our bodies thanks to our diet, by consuming foods with NAD+ precursors in them. While NR and NMN can be found in trace amounts in various foods, though, one can’t eat enough of anything to boost NAD+ levels. As a result, supplementing with an NAD+ precursor can help mitigate the decline. Anim...
