NAD(+) precursor supplementation in human ageing: clinical evidence and challenges
Nicotinamide adenine dinucleotide (NAD^(+)) is an essential molecule involved in cellular metabolism, and its decline has been implicated in ageing and age-related disorders. However, evidence for an age-related decline in NAD^(+) levels in humans has been consistently observed only in a limited number of studies.
