Nicotinamide Riboside Chloride (NR-Cl)
|
Nicotinamide Riboside Chloride is the chloride salt form of nicotinamide riboside(NR).NR is a new form pyridine-nucleoside of vitamin B3 that functions as a precursor to nicotinamide adenine dinucleotide(NAD) or NAD+ . Nicotinamide riboside chloride is a crystal form of Nicotinamide riboside (NR) chloride. Nicotinamide riboside chloride increases NAD[+] levels and activates SIRT1 and SIRT3, culminating in enhanced oxidative metabolism and protection against high fat diet-induced metabolic abnormalities. Nicotinamide riboside chloride is used in dietary supplements.

Nicotinamide riboside
|
Nicotinamide riboside is an orally active NAD(+) precursor essential for cellular energy and metabolic functions. It Supplementation increases NAD(+) levels, activating sirtuins like SIRT1 and SIRT3, which improve oxidative metabolism and provide protection against metabolic issues induced by a high-fat diet. It also helps to reduce cognitive decline in a transgenic mouse model of Alzheimer's disease.
