Nicotinamide riboside is widely used as a dietary supplement to boost cellular energy production by increasing levels of NAD+ (nicotinamide adenine dinucleotide), a crucial coenzyme in metabolism. It is often promoted for its potential anti-aging benefits, as it supports mitochondrial function and cellular repair processes. Additionally, it is studied for its role in improving cardiovascular health, enhancing cognitive function, and reducing fatigue. Some research suggests it may aid in managing metabolic disorders and supporting muscle health during aging. Its applications extend to potentially mitigating neurodegenerative diseases and improving overall vitality.
