The vitamin B3 derivative nicotinamide riboside is one of the more studied ways to increase nicotinamide adenine dinucleotide (NAD) levels in aged tissues. NAD is important in mitochondrial function, but for incompletely understood reasons becomes less available with advancing age. Delivering precursors to NAD synthesis such as nicotinamide riboside can help to boost NAD levels, but researchers have failed to show that the increase in NAD levels and resulting health benefits of this sort of approach are any better than those produced by regular exercise. Clinical trials of various means of increasing NAD levels have pr…
