Niacin is known as vitamin B3. Its role in the body is much like that of thiamine and riboflavin; it is a coenzyme (or component) during the chemical reactions which release energy in your body. Lack of niacin, however produces a specific condition called pellagra. Pellagra is an Italian word means “Rough skin,” and aptly describes the red rash which appears first on the hands, face and feet when they are exposed to sunlight. Untreated, intestinal problems and mental disturbance may result. Because niacin can be synthesized by bacteria in intestines and can also be formed from the amino acid tryptophan, the actual requirement is difficult to calculate. Current value of niacin for a pregnant woman is 18 mg. Niacin content of foods is not significantly affected by most cooking and storage techniques.
