Niacin is a water-soluble B3 vitamin that is naturally found in foods such as nuts, legumes, poultry, fish, dairy products and other animals and plants.http://lpi.oregonstate.edu/infocenter/vitamins/niacin/ It is water-soluble, which means that any amount that is not absorbed by the body will be flushed out through the urine, so it is important to get a constant supply of this essential vitamin through a healthy diet. http://www.nlm.nih.gov/medlineplus/ency/article/002409.htm

In addition to a healthy diet, vitamins and supplements containing niacin can help to maintain an adequate supply of this nutrient in the body. It is also used medically in prescription doses to help lower chlotesterol, to maintain proper levels of blood triglycerides, and to lower the risk of repeat heart attacks for high cholesterol patients. If you have these cholesterol issues see your doctor for full details, and use only as directed by your physician or pharmacist. http://www.drugs.com/niacin.html
