Niacin (vitamin B3) is an essential nutrient with important functions for maintaining cardiovascular, neurological and overall health. Niacin supplements containing nicotinic acid can cause uncomfortable flushing. No Flush Niacin contains a special form of niacin, inositol hexanicotinate, consisting of six molecules of niacin chemically linked to an inositol molecule.

Some of the ingested inositol hexanicotinate is hydrolyzed in the body to slowly release free niacin and inositol.^1,2 However, because much of it remains intact in the body, it is thought that inositol hexanicotinate may exert direct effects in addition to those of its constituent inositol and niacin fractions, without causing the characteristic niacin flush.²
