Beta-nicotinamide is integral to the synthesis of nicotinamide adenine dinucleotide (NAD+), a coenzyme that is essential for various metabolic reactions. NAD+ is involved in catabolic pathways that help convert food into energy, allowing cells to generate ATP—the energy currency of the cell. By facilitating the conversion of nutrients into usable energy, beta-nicotinamide supports vital functions, including DNA repair, cell signaling, and the regulation of metabolic processes.
