Inositol hexanicotinate (IHN), also known as inositol hexaniacinate, is the inositol esterified with niacin.
IHN undergoes hydrolysis in the body, gradually releasing nicotinic acid and inositol. Such properties make this form not only very effective but also free of the side effect referred to as flush effect (redness mainly on the face, forearms and neck), which occurs in standard forms of niacin and is very unpleasant for many individuals.
Inositol hexanicotinate is a component of niacin-based dietary supplements. It is suggested that inositol hexanicotinate is as effective as niacin alone (may contribute to lowering cholesterol levels). Because of decreased risk of such symptoms as skin redness, itching and tingling, it can be a perfect solution for persons who resign from traditional vitamin B3 supplements due to these unpleasant effects.
