Cholesterol

Niacin

Niacin (also called nicotinic acid) is a B vitamin. When given in large doses, it can lower your levels of triglycerides and LDL cholesterol, and increase your HDL cholesterol level. Even though you can buy niacin without a prescription, you should not take it to lower your cholesterol unless your doctor prescribes it for you. It can cause serious side effects.
