NR

Meaning

NR, or Nicotinamide Riboside, is a specific form of Vitamin B3 (niacin) that functions as a direct precursor to Nicotinamide Adenine Dinucleotide (NAD+), a critical coenzyme found in every cell of the body. NAD+ is essential for hundreds of metabolic processes, including energy production, DNA repair, and gene expression regulation. As a nutritional supplement, NR is studied in the longevity and wellness space for its potential to boost cellular NAD+ levels, thereby supporting mitochondrial function and cellular resilience against metabolic stress and aging.
