What is Nicotinamide Riboside?

Nicotinamide Riboside (NR) is a unique form of vitamin B3 (niacin) and a naturally occurring pyridine-nucleoside. Like NMN, NR acts as a direct precursor to NAD+ (Nicotinamide Adenine Dinucleotide) , the essential coenzyme found in every living cell.

What makes NR distinct is its molecular structure—it is a nucleoside composed of niacin and ribose (a sugar). This structure allows NR to be absorbed through different transport mechanisms than NMN, with some research suggesting it may be even more bioavailable in certain tissues.
