Vitamin B3 is one of 8 B vitamins. It is also known as niacin (nicotinic acid) and has 2 other forms, niacinamide (nicotinamide) and inositol hexanicotinate, which have different effects from niacin. All B vitamins help the body convert food (carbohydrates) into fuel (glucose), which the body uses to produce energy.
Niacin also is known as vitamin B3, a vitamin necessary to build fatty acids and red blood cells and convert carbohydrates, fats and proteins into energy. While niacin has important functions, it is possible to be allergic to foods that contain it. When you experience an allergic reaction to niacin, your body treats it like a foreign invader, resulting in inflammatory symptoms like a rash, breathing difficulty or itching skin.
