Nicotinamide Riboside (NR)

Nicotinamide Riboside (NR) is a naturally occurring, highly efficient form of vitamin B3. It acts as a direct precursor to nicotinamide adenine dinucleotide (NAD+), an essential coenzyme found in all living cells that is critical for biological function. NAD+ naturally declines as we age, a process closely linked to metabolic stress and age-related physiological decline. As a dietary supplement—often available and stabilized as Nicotinamide Riboside Chloride (NRCl)—NR is utilized to replenish these dwindling NAD+ pools, addressing cellular aging, vitality, and energy metabolism at their source.
