Although the exact mechanism of action by which niacin lowers cholesterol is not fully understood, it may act by inhibiting the synthesis of very low density lipoproteins (VLDL), inhibiting the release of free fatty acids from adipose tissue, increasing lipoprotein lipase activity, and reducing the hepatic synthesis of VLDL-C and LDL-C.

(Niacin, NCI Thesaurus)

Increased lipolysis and a fall in plasma triglycerides, in turn, leads to the modification of the small, dense low density lipoporotein (LDL) particles into larger particles that are catabolized more rapidly due to a greater affinity for cholesterol receptors.
