Vitamin B3 is called niacin, an essential nutrient for the human body. In diet, it exists in three forms - niacin, nicotinamide, and nicotinamide riboside and can also be produced from an amino acid - tryptophan in the gut. During the digestive process, these dietary forms of vitamin B3 get converted into nicotinamide adenine dinucleotide (NAD), which behaves as a cofactor and substrate in critical cellular reactions and thus plays a pivotal role in energy metabolism.
