Niacinamide - Nicotinamid - (Vitamin B3 form) 

Niacinamide, also known as nicotinamide and nicotinic acid amide, is a water-soluble vitamin made from niacin in the body. When niacin exists in greater amounts than needed, it is converted into niacinamide. Both niacin and niacinamide are part of the B complex vitamins, making up vitamin B3. This vitamin is needed to keep cells healthy and to produce fatty acids. Niacinamide is a component of the coenzymes called nicotinamide adenine dinucleotide phosphate (NADP) and nicotinamide adenine dinucleotide (NAD). It combines with them to convert glycogen into glucose and to release energy from body tissues. Other functions include helping to heal broken DNA strands and keeping the central nervous system functioning well. Vitamin B3 is found in a large variety of foods, including yeast, milk, fish, eggs, meat, beans, green vegetables, and cereals. Often it is combined with the other B vitamins as a supplement. Proper amounts can usually be obtained by eating a healthy, varied diet. Deficiency can cause a condition called pellagra. Symptoms of this disease include diarrhea, skin irritations, and dementia. This is not frequently seen today because many foods are vitamin fortified. It was very common in the early 20th century, however.
