Vitamin B3 details
Description
Niacin (vitamin B3) is involved in energy metabolism and plays important roles in skin health and nervous system function. Deficiency, historically known as pellagra when severe, causes a distinctive pattern of skin, digestive, and neurological symptoms, and while uncommon today in developed countries with fortified grain products, it can still occur with very restrictive diets, alcohol use disorder, or certain malabsorption conditions. This test is used to evaluate niacin status when deficiency is a clinical concern based on symptoms or risk factors.
