Cardiovascular disease#N#Very high doses of nicotinic acid—more than 100 times the RDA—taken for months or years are effective treatments for dyslipidemias. Nicotinamide does not have this effect because, unlike nicotinic acid, it does not bind to the receptors that mediate nicotinic acid’s effects on lipid profiles [ 1 ]. Studies conducted since the late 1950s show that these doses can increase high-density lipoprotein (HDL; “good”) cholesterol levels by 10-30% and reduce low-density lipoprotein (LDL; “bad”) cholesterol levels by 10-25%, triglyceride levels by 20-50%, and lipoprotein (a) levels by 10-30% [ 12 ]. Together, these changes in lipid parameters might be expected to reduce the risk of first-time or subsequent cardiac events, such as heart attacks and strokes, in adults with atherosclerotic cardiovascular disease. However, despite dozens of published clinical trials, experts do not agree on the value of nicotinic acid to treat cardiovascular disease, especially given its side effects, safety concerns, and poor patient compliance [ 24 ].
