Vitamin B3 occurs naturally in the body in two forms, niacin (nicotinic acid) and niacinamide (nicotinamide). Niacinamide can be produced from niacin in the body. Although excessive niacin supplementation can result in niacin “flushing”, large doses of niacinamide do not normally cause “flushing”.

Vitamin B3 contributes to the normal metabolism of energy production, helps to reduce tiredness and fatigue and supports the maintenance of healthy skin and normal mucous membranes.
