Used as a dietary supplement to boost cellular energy and support metabolic health. It is known for its role in increasing levels of nicotinamide adenine dinucleotide (NAD+), a coenzyme involved in energy production, DNA repair, and cellular aging. Commonly included in anti-aging and wellness products due to its potential to improve mitochondrial function. Also studied for its neuroprotective effects and possible benefits in age-related conditions such as cognitive decline and muscle fatigue. Used in research settings to explore longevity pathways and metabolic regulation.
