Explore NAD+, the naturally occurring coenzyme involved in cellular energy, metabolism and the processes that keep our cells functioning.
Nicotinamide adenine dinucleotide (NAD+) is a coenzyme present in living cells.
It participates in essential chemical reactions, helping cells process nutrients and transfer electrons during metabolism. Its reduced counterpart, NADH, is involved in energy-producing pathways.
NAD+ is also used by enzymes involved in cellular signalling and responses to DNA damage.
Present naturally in the body. Central to metabolism. An active area of scientific investigation.
Researchers study NAD+ across numerous cellular functions. Biological importance does not, by itself, establish a clinical benefit from NAD+ products.
NAD+/NADH reactions are fundamental to energy metabolism and ATP production.
NAD+ is used by enzymes that take part in responses to cellular DNA damage.
Scientists are exploring changes in NAD+ metabolism that may occur with age.
NAD+ participates in oxidation–reduction reactions throughout cellular metabolism.
Researchers investigate NAD+ pathways in neurons and other nervous-system cells.
NAD+-dependent enzymes contribute to signalling and cellular stress responses.
Research has identified age-related changes in NAD+ levels in some tissues and populations, although findings vary with tissue, health and measurement methods.
Scientists are studying whether changing NAD+ metabolism can influence age-related biological processes. There is not yet robust clinical evidence that NAD+ products reverse ageing or reliably improve longevity in people.
One important role is helping cells transfer electrons through metabolic pathways.
Carbohydrates, fats and other nutrients enter networks of metabolic reactions.
In many reactions NAD+ accepts electrons and becomes NADH.
NADH can be converted back to NAD+, allowing the cycle to continue.
A clear introduction to the science, without exaggerated promises.
Yes. NAD+ occurs in living cells and is continuously produced, recycled and used during normal metabolism.
No. NAD+ is a coenzyme. Certain forms of vitamin B3 can serve as precursors in pathways that produce NAD+.
NAD+ is essential to cellular metabolism, but strong clinical evidence that commercial NAD+ products improve these everyday outcomes remains limited and formulation-dependent.
No NAD+ product has been established as reversing human ageing. Research continues into the relationship between NAD+ metabolism and age-related biology.
No. Formulation, absorption, risks, routes of administration and evidence differ. Injectable products require particular medical and regulatory consideration.
