Niacinamide 500 mg is a single-ingredient capsule supplement made by Douglas Laboratories, providing 500 mg of niacinamide (nicotinamide) per capsule in a 100-capsule bottle.
Vitamin B3 occurs naturally in the body in two forms: niacin (nicotinic acid) and niacinamide (nicotinamide). Niacinamide can be synthesized from niacin within the body. Unlike niacin, large doses of niacinamide do not typically cause vasodilation or the niacin "flush" associated with niacin supplementation in amounts greater than the body requires.
Niacinamide is a precursor to the metabolically active coenzymes NAD (nicotinamide adenine dinucleotide) and NADP (NAD phosphate), which participate pervasively in the electron-transport chain and oxidation-reduction reactions. At least 200 enzymes depend on these vitamin B3 cofactors. Independent of its role as a coenzyme precursor, niacinamide may support healthy skin and joints, and the proper metabolism of glucose.
This product is intended for adults who wish to increase their dietary intake of niacinamide and may be a useful nutritional adjunct for that purpose. The capsule is formulated with gluten-free, non-GMO ingredients.
