According to the recommendation of the German Nutrition Society (DGE), adults should consume nicotinic acid or niacin as a vitamin of the B complex in a daily amount of approx. 11 - 17 mg.
Niacin is an important vitamin for the human body. It is also known as vitamin B3 and is water-soluble. Niacin consists of the compounds nicotinic acid, nicotinamide and pyridine nucleotide coenzymes. Humans can produce the vitamin on their own. It is produced from the amino acid tryptophane itself. The production takes place in the liver of the human body. Niacin is involved in many processes. These include cell division and energy metabolism.
