NAD precursors

Topic

NAD precursors are chemical compounds that serve as building blocks for the synthesis of nicotinamide adenine dinucleotide (NAD+), an essential coenzyme involved in cellular metabolism, energy production, and DNA repair. Key precursors include nicotinamide riboside (NR), nicotinamide mononucleotide (NMN), nicotinamide (NAM), nicotinic acid (NA), and tryptophan. Supplementation with these compounds is widely studied for its potential to boost NAD+ levels, which naturally decline with age, to promote longevity and metabolic health.
