Inositol hexaniacinate (IHN) is the hexanicotinic acid ester of meso-inositol. This compound consists of six molecules of nicotinic acid (niacin) with an inositol molecule in the center.

IHN lowers LDL and triglyceride levels by decreasing VLDL synthesis in the liver.


Pharmacokinetic studies have indicated that these esters are absorbed intact and hydrolyzed in the body with release of free niacin and inositol.
