Vitamin B-3 forms the active portion of coenzymes that play an essential role in tissue oxidation and the production of energy. It is also involved in the metabolism of fats (i.e., cholesterol). The most common question regarding this B complex vitamin is if there is a difference between niacin and niacinamide. The difference, chemically, lies in the fact that niacin contains an organic acid group while niacinamide contains an amino group. The amino acid tryptophan is chemically converted to niacin in the body tissues and a small amount can be synthesized by the intestinal flora. Once in the body, niacin is converted into niacinamide. In many individuals, the use of niacin often results in the side effect known as "flushing". This reaction can be described as a sensation of warmth, itching or tingling, especially around the face, neck and ears. Though generally harmless, flushing can alarm an individual who is not prepared for such a reaction. Flushing normally lasts for 10 to 20 minutes. Although niacinamide does not cause flushing, it can produce nausea in about one percent of the people who take it.
