Nicotinamide derivatives are compounds related to nicotinamide, a form of vitamin B3. These derivatives include various forms such as nicotinamide riboside and nicotinamide adenine dinucleotide (NAD+). They play essential roles in cellular metabolism and energy production, helping to convert food into energy. These compounds are also studied for their potential health benefits, including promoting skin health and supporting cellular repair. Research suggests that nicotinamide derivatives may help improve conditions like diabetes and neurodegenerative diseases by enhancing cellular function and reducing oxidative stress.
