Research has demonstrated its role in mitochondrial biogenesis, DNA repair coordination, and regulation of circadian clock machinery. Declining NAD+ levels are associated with metabolic dysfunction and cellular ageing. Research applications span metabolic disease, neurodegeneration, and longevity biology.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eStorage\u003c\/strong\u003e\u003cbr\u003eStore at 2–8°C.
