Niacin, or vitamin B-3 is a generic term used to refer to two different compounds, nicotinic acid and niacinamide. Either form is converted in the body to the physiologically active forms that are required in many metabolic processes. Niacin is involved in the metabolism of carbohydrates, protein and fat and the generation of energy from foods. Niacin is needed in the formation of red blood cells and some hormones, and in the metabolism of some drugs and toxicants. Niacin is also required in the production of hydrochloric acid. Niacin also supports normal central nervous system function and is important to the health of the skin and helps maintain normal digestive tract function. Niacin can be manufactured in the body from the essential amino acid tryptophan. Niacin, in the form of nicotinic acid can produce a niacin flush. This is a redness, warmth, and itching to the skin. This typically happens when the dosage is 50 mg or higher. The flush is the result of vasodilation. While some find this feeling uncomfortable, it is harmless. Nicotinic acid stimulates circulation, helps maintain normal blood
pressure and blood triglyceride levels. Nicotinic acid is very effective
at lowering LDL cholesterol while raising HDL cholesterol, both of which
support normal cholesterol levels. Niacin is also known as: Vitamin B3, Niacinamide, Nicotinic Acid
