If you want to lower your LDL and TG and raise your HDL, take immediate release niacin (OTC), slow-release niacin (Slo-Niacin – OTC) or extended-release niacin (Niaspan – Rx). Ask your pharmacist for more information.
-the most recent published information I could find upon cursory search is Meyers CD, Carr MC, Park S, Brunzell JD. Varying cost and free nicotinic acid content in over-the-counter niacin preparations for dyslipidemia. Ann Intern Med. 2003;139(12):996-1002.
Yes, based on the open scientific literature it lowers high cholesterol better than does plain Niacin. Basically triglycerides (VLDL) are reduced and HDL is increased (a very good thing). You can expect your total cholesterol to approach a more normal value.
The decrease expected (dTC) from your initial total cholesterol level (TC) varies according to ones’ body weight (Wgt) by the equation:
dTC = 0.95(TC) – 0.39(Wgt) – 90 (from Abram Hoffer M.D. Ph.D)
Dr Hoffer notes that total cholesterol levels will rise if the initial level was abnormally low for the patient’s body weight (here a negative dTC is an increase).

“Derivatives of niacin have been examined for their ability to alter lipid levels as well as niacin. It would be advantageous if the niacin vasodilation (flush) were eliminated or removed. The main disadvantage of the niacin derivatives will be cost. Inositol hexanicotinate is an ester of inositol and niacin. In the body it is slowly hydrolyzed releasing both of these important nutrients. The ester is more effective than niacin in lowering cholesterol and triglyceride levels, Abou El-Enein, Hafez, Salem and Abdel (1983). I have used this compound, Linodil, available in Canada but not the U.S.A. (at the time this paper was written) for thirty years for patients who can not or will not tolerate the flush. It is very gentle, effective, and can be tolerated by almost every person who uses it.”
