Niacin (nicotinic acid), a B vitamin, is one of the oldest drugs used to treat high blood-cholesterol levels. Unlike its nonflushing counterpart, niacinamide, niacin displays potent LDL cholesterol- and triglyceride-lowering effects and HDL cholesterol-elevating effects. Niacin has also been shown to help reverse hardening of the arteries and to decrease the incidence of heart disease and its associated deaths, qualities that distinguish it from other dietary supplements.

Results of a recent study suggest that 2.1 g/day niacin can produce cardioprotective effects in people with heart disease risk factors, including high triglycerides, low HDL cholesterol, and an abundance of smaller, more dense LDL cholesterol.  Niacin has not been used more often in cardiovascular treatment because of the high doses needed to reverse the disease (in excess of 1,000 mg/day), and the sometimes uncomfortable skin flushing that follows 15-60 minutes after ingestion. Time-released niacin formulations can be gradually increased daily up to a maximum tolerable dose. Taking niacin with one baby aspirin before a meal can reduce the flushing effect. Patients should consult with a physician before implementing high-dose niacin therapy.
