*'''[[Nicotinamide (NAM)]]:''' NAM, a form of vitamin B3, is also a precursor of NAD+, contributing to its synthesis through the salvage pathway. NAM is converted to NMN by the enzyme nicotinamide phosphoribosyltransferase (NAMPT). | *'''[[Nicotinamide (NAM)]]:''' NAM, a form of vitamin B3, is also a precursor of NAD+, contributing to its synthesis through the salvage pathway.

*'''[[Nicotinic Acid (NA)]]:''' NA, another form of vitamin B3, serves as a precursor of NAD+ through the Preiss-Handler pathway. NA is converted to NAD+ via a series of enzymatic reactions, first to nicotinic acid mononucleotide (NAMN), then to nicotinic acid adenine dinucleotide (NAAD), and finally to NAD+. | *'''[[Nicotinic Acid (NA)]]:''' NA, another form of vitamin B3, serves as a precursor of NAD+ through the Preiss-Handler pathway.

*[[Reduced Nicotinamide Mononucleotide (NMNH)]]: A new and efficient NAD+ precursor, NMNH operates via a novel metabolic pathway that is independent of the enzymes NRK (Nicotinamide Riboside Kinase) and NAMPT (Nicotinamide Phosphoribosyltransferase). | |||
