Product information

What it is NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme found in every living cell. It is not a peptide or a hormone, and its role starts at a much more basic level of cell biology. Cells need this coenzyme for energy metabolism, DNA repair and a range of signaling processes. One of its best-known jobs involves energy. The molecule moves between oxidized and reduced forms as cells process nutrients, carrying electrons through reactions involved in ATP production. Mitochondria depend heavily on this chemistry. There is more to it than that. The coenzyme also activates sirtuins, proteins involved in metabolic signaling, inflammation and DNA repair. This puts the same molecule into several quite different areas of research. Levels do not stay the same Age is one of the factors researchers have looked at. Studies have reported declines of up to 50% across different tissues, together with reduced mitochondrial efficiency, slower DNA repair and increased markers of cellular senescence. The picture in humans is still being worked out, though. Levels vary between tissues, and the available human data are much less extensive than the evidence from experimental models. Recent studies have approached the subject from different directions. In a human trial published in  Nature Metabolism  in January 2026, the precursors NMN a
