01 · Why it matters
What is Nicotinamide adenine dinucleotide (NAD+)?
It's a vital coenzyme found in every living cell that plays a central role in energy production, DNA repair, and cellular metabolism.
Cellular energy
Shuttles electrons that drive ATP production in mitochondria.
DNA repair
Powers PARP enzymes that maintain genome integrity.
Metabolism & sirtuins
Required to activate sirtuins, the regulators of cellular aging.
02 · The science
Peer-reviewed scientific literature
Cellular energy & ATP
NAD+ is the electron carrier at the heart of glycolysis and mitochondrial oxidative phosphorylation.
Verdin E. Science, 2015
Sirtuin activation
Sirtuins are NAD+-dependent enzymes that regulate metabolism and are linked to healthy aging.
Imai S, Guarente L. Trends Cell Biol, 2014
DNA repair (PARPs)
PARP enzymes consume NAD+ to detect and repair DNA strand breaks.
Fang EF et al. Cell Metab, 2016
