“Niacin. This supplement, also called vitamin B3, has earned a reputation as a natural cholesterol-lowering agent that often rivals prescription drugs in mild to moderate cases. Unlike most prescription cholesterol-lowering medications, which simply lower levels of LDL cholesterol and the bad fats found in triglycerides, niacin also raises levels of HDL cholesterol. As a result, this vitamin may prove more potent than conventional medicines in ultimately reducing the risk of a heart attack.”
