“No-flush”
niacin preparations, such as inositol hexaniacinate
and nicotinamide, are widely sold as
niacin alternatives that do not cause hot flushes. In my experience, however, they simply do not work. In other words, no flush, no effect.
The correct dose of niacin depends on what abnormality you and your doctor are trying to correct. To raise HDL and correct small LDL, a dose of 750-1000 mg a day usually provides full benefit.
