Nicotinamide adenine dinucleotide CAS # 53-84-9
- NAD+, or nicotinamide adenine dinucleotide, is a coenzyme that supports many of the body’s biological processes. NAD+ helps protect cells from stress, supports healthy sleep cycles and helps repair damaged DNA.

Nicotinamide riboside (NR) is now known to be an NAD+ precursor, involved in the biosynthetic pathways that convert B3 vitamins into NAD+. NAD+ is primarily synthesized in mammals de novo from tryptophan, through the Priess-Handler pathway from nicotinic acid (NA) or via a salvage pathway from nicotinamide (NAM).
