Vitamin B3 is a vitamin that includes three forms: nicotinamide (niacinamide), niacin (nicotinic acid), and nicotinamide riboside.[1] All three forms of vitamin B3 are converted within the body to nicotinamide adenine dinucleotide (NAD).[1] NAD is required for human life and people are unable to make it within their bodies without one of the vitamin B3 or tryptophan.[1] Nicotinamide riboside was identified as a form of vitamin B3 in 2004.[1] The group is also occasionally referred to as vitamin B3 complex.[2]
