Niacin SR™ is NuMedica’s sustained release niacin features an advanced carnauba wax coating designed to release part of the niacin rapidly with the rest being released over several hours with little or no flushing. Niacin supports blood lipid levels related to cardiovascular health by reducing the production of LDL and VLDL in the liver and boosting the production of beneficial HDL which draws cholesterol away from the lining of the arteries. Niacin also removes triglycerides from the blood through “lipoprotein lipase activity” and has a powerful effect on the production of prostaglandins. Niacin dilates the blood vessels, improving circulation and may encourage flushing out existing plaque.
