2018 Nature Communications paper (NR reduced blood pressure and arterial stiffness in healthy middle-aged adults), and numerous pharmacokinetic studies Animal lifespan data: While NAD+ precursors have shown healthspan improvements in mice (improved physical activity, insulin sensitivity, mitochondrial function), clear lifespan extension data is more limited and inconsistent DNA repair: Studies demonstrated restored PARP-dependent DNA repair in aged mice and radiation-exposed human cells following NAD+ repletion Stem cell rejuvenation: NMN restored aged muscle stem cell function and improved hematopoietic stem cell parameters in mice Epidemiological data: NAD+ levels correlate with biological age across multiple cohort studies, establishing translational relevance Key limitations: Despite abundant evidence for NAD+ restoration, the downstream clinical benefits in humans are still being established
