Flush-free niacin may lower cholesterol while boosting the beneficial HDL fraction. In a report on the antiatherogenic role of HDL (high density lipoprotein) cholesterol, flush-free niacin (inositol hexanicotinate) "appears to have the greatest potential to increase HDL cholesterol by 30%." This study was made over a 5-year period and focused on the effect of high LDL numbers exhibited before a patient's first coronary event(s).
As reported in a November 1998 American Journal of Cardiology research study, "Nicotinic acid (niacin) has been shown to decrease triglyceride, increase HDL cholesterol, lower LDL cholesterol, and decrease lipoprotein (a); it also decreases fibrinogen," an additional benefit that reduces the risk of related cardiovascular disease.
