Niacin, also known as vitamin B3 or nicotinic acid, is recognized as a cardioprotective agent, primarily due to its action in inhibiting triglyceride hydrolysis, leading to both an increase in HDL and a decrease in triglyceride levels. In fact, niacin has been linked to an increase in HDL by up to 30%. In the body, its main function is as a component of the coenzymes NAD+ and NADP+, both of which function in the redox state of the cell. In addition to these actions, it has also been confirmed to hinder vascular inflammation, through its action on decreasing the production of endothelial reactive oxygen species (ROS) and the subsequent oxidation of LDL, as well as decreasing the production of inflammatory cytokines.
