By far, the greatest source of NAD + is thru the salvage pathway.

DNA damage is repairable, but PARPS consume up to 80 % of available NAD + in older humans, meaning it is a major cause of NAD + shortage, leaving less NAD + for cellular respiration, fighting inflammation, and disease (21)

Interestingly, younger mice did not benefit from NMN supplementation (likely due to the fact that the body naturally produces higher levels of NAD at younger ages), but as the mice aged, the supplementation significantly reduced signs of aging.

The researchers then concluded that as the amount of NAD + in cells declines with age, there aren't enough of these molecules to prevent harmful interactions between proteins called DBC1 (which is found across a wide range of organisms, from bacteria to humans) and PARP1 (a protein that is known to control DNA repair).
