Niacin is essential for the production of energy, is involved in blood sugar regulation, antioxidant mechanisms, detoxification and in regulation of cholesterol levels.  It works in conjunction with the other B vitamins.  It can be manufactured in the body from tryptophan, but dietary sources are also important.
