Nicotinamide riboside (NR) is the big brother of nicotinamide mononucleotide (NMN) and, as a bioactive vitamin B3 variant, the immediate precursor of NAD. The coenzyme NAD+ controls important metabolic processes and thus determines the function of the cells. The brand raw material NIAGEN® convinces with its high purity (over 99.9%) and has been used in all clinical NR studies. The elegant combination with betaine (TMG) refines the longevity recipe of this product.
