Niacin can boost 39good39 cholesterol - Mayo Clinic

Niacin is a B vitamin that may raise your HDL ("good") cholesterol. But side effects might outweigh benefits for most people.

Niacin (nicotinic acid) is a B vitamin that's used by your body to turn food into energy. Niacin also helps keep your nervous system, digestive system, skin, hair and eyes healthy. That's why niacin is often a part of a daily multivitamin, though most people get enough niacin from the food they eat.

Niacin, a B vitamin, has long been used to increase high-density lipoprotein (HDL) cholesterol — the "good" cholesterol that helps remove bad cholesterol from your bloodstream.

Don't take niacin without discussing it with your doctor first because niacin can cause serious side effects when taken in high doses.

When it's used as a treatment to increase your HDL cholesterol or correct a vitamin deficiency, niacin is sold in higher doses that are prescribed by your doctor. Prescription-strength niacin includes such drugs as Niacor and Niaspan.

But niacin isn't for everyone. People who take niacin in addition to common cholesterol medications see very little additional benefit. And niacin can cause uncomfortable and sometimes dangerous side effects.

Niacin can raise HDL cholesterol by more than 30 percent. HDL, the "good" cholesterol, picks up excess bad cholesterol in your blood and takes it back to your liver for disposal.

Niacin is also available as an over-the-counter supplement. Supplements sold over-the-counter are not regulated like prescription medications. The ingredients, formulations and effects of over-the-counter niacin can vary widely.
