NMN, short for Nicotinamide Mononucleotide, is a tiny molecule that’s found in every cell of living things, including humans. It’s like one of the building blocks that helps make up our DNA and RNA, which are the instructions our bodies use to grow and stay healthy. NMN is special because it can turn into another important molecule called NAD+. NAD+ is really important because it helps our cells make energy and stay strong, which is why NMN is sometimes called an NAD+ booster.
