NAD+

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme present in every living cell, central to mitochondrial electron transport, sirtuin-family deacetylase activity, and DNA-repair signaling through PARP enzymes. Cellular NAD+ levels decline measurably with age across mammalian models and human tissue. Research focuses on NAD+ as a substrate for sirtuins (SIRT1, SIRT3), its role in mitochondrial bioenergetics, and the pharmacokinetics of direct NAD+ versus precursor compounds (NMN, NR, nicotinamide). Studies in aging biology, neurodegeneration, and metabolic health continue to expand. Note: NAD+ is a coenzyme, not a peptide. It's included in this catalog for researchers studying cellular bioenergetics and longevity pathways. For research use only. Not for human consumption.
