The distinct and tissue-specific biosynthetic and/or ligand activities of tryptophan, nicotinic acid, nicotinamide, and the newly identified NAD(+) precursor, nicotinamide riboside, reviewed herein, are responsible for vitamin-specific effects and side effects. Because current data suggest that nicotinamide riboside may be the only vitamin precursor that supports neuronal NAD(+) synthesis, we present prospects for human nicotinamide riboside supplementation and propose areas for future research. Expected final online publication date for the Annual Review of Nutrition Volume 28 is July 17, 2008.
