Chemical composition: Under the names niacin, PP factor, or vitamin B3, two equally active natural substances are included: nicotinic acid (this has nothing to with the nicotine in tobacco), which is present in vitamin B3 foods as well as plant-based foods, and nicotinamide, which is found in milk, eggs, fish, and meat.
Vitamin B3 sources: Foods provide niacin in either of these forms or both
Units of measure: The niacin content of foods is measured in mg of niacin equivalents (mg NE). This measure includes the performed niacin present in a food and that formed from tryptophan.
Vitamin B3 function: Intervenes as a coenzyme in cell energy production. It is necessary for body growth. Niacin from plant sources (nicotinic acid) reduces cholesterol levels. Niacin from animal sources (nicotinamide) does not have the same effect.
Vitamin B3 deficiency: Skin disorders (dermatitis, pellagra in advanced cases) and nervous system disorders (depression, anxiety).
Increased need: Periods of growth, pregnancy, skin, and nervous system disorders.
Loss during the processing of foods: Niacin is the most stable of all vitamins and deteriorates very little with heat, freezing, or long-term food storage.
