Research classification: Biochemical and translational research
Compound overview
Nicotinamide adenine dinucleotide (NAD+) is a dinucleotide coenzyme, not a peptide. It participates in electron-transfer reactions and is a substrate for multiple enzyme families.
Published research
Reviews address NAD+ synthesis, consumption, cellular metabolism, and roles in signaling. Studies of oral NAD+ precursors are distinct from studies of direct NAD+ administration.
Evidence limitations
An established biological role does not imply that externally administered NAD+ improves health or produces a particular clinical outcome. Evidence on one delivery method cannot be transferred to another.
