Vitamin B3 (niacin) is important for the body because it helps to: 1  Convert food into glucose, used to produce energy. 2  Produce macromolecules, including fatty acids and cholesterol. 3  Facilitate DNA repair and stress responses.
Niacin has a half-life of 20-40 minutes in the human body. The most reliable and sensitive method of measuring niacin status is through urinary excretion. For adults, 24-hour excretion rates less than 5.8 Âµmol/day indicate niacin deficiency while 5.8 to 17.5 Âµmol/day indicate low levels of niacin.
