It is fundamental to mitochondrial function, DNA repair, and cellular energy production. NAD+ levels decline sharply with age, and low NAD+ is associated with many hallmarks of ageing.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 dir=\"ltr\"\u003e\u003cspan\u003eHow it works\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eNAD+ works as a cofactor for enzymes called sirtuins and PARPs, which regulate DNA repair and cellular longevity pathways.
