Nicotinic acid is a derivative of vitamin B3 and is incorporated into coenzymes nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP), which are involved in multiple cellular metabolic pathways. Nicotinic acid also reduces total serum cholesterol, LDL, VLDL, and triglycerides, and increases HDL cholesterol. It appears to decrease hepatic synthesis of VLDL, however, the exact mechanisms of nicotinic acid's antilipemic effects are unknown and are unrelated to its role as a vitamin.
