What Nicotinamide Riboside is
A well-studied vitamin B3 form and NAD+ precursor that reliably raises NAD+ levels in humans, widely used in longevity supplement stacks.
Nicotinamide riboside is a form of vitamin B3 that the body converts into NAD+, the coenzyme central to energy metabolism and cellular repair. Human trials show it safely and reliably raises NAD+ levels, and it is one of the most studied NAD+ precursors, sold as a supplement (for example Niagen).
Mechanism: Converts to NAD+ through the salvage pathway, restoring NAD+ that declines with age and supporting mitochondrial and repair enzymes.
Regulatory history: Sold as a supplement; not an approved drug
