Niacin (Vitamin B3) Benefits and Uses


Chemically, Niacin is easily converted by the body tissues into nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide (NADP), enzymes which catalyze hundreds of important reactions in the body. Among these are the ability to convert food into usable energy and to repair DNA damage. 


Anecdotally, Niacin B3 has perceived health benefits on cardiovascular health, circulation and may improve cognition.
