Niacin, also called Vitamin B3, is a water-soluble B vitamin needed for energy metabolism, nervous system function, skin health and normal psychological function.
Niacin appears in several forms, including nicotinic acid, niacinamide and inositol hexanicotinate. These forms are not identical. Nicotinic acid can cause the well-known “niacin flush.”
