What Anti-Aging Benefits Are Plausible Versus Unproven?
Anti-aging benefits are often described in terms of DNA repair, sirtuin activity, mitochondrial function, inflammation, and cellular senescence. These pathways are scientifically relevant to ageing biology [4], [5], [14]. What remains unproven is much broader:

- Anti-aging benefits are often described in terms of DNA repair, sirtuin activity, mitochondrial function, inflammation, and cellular senescence. These pathways are scientifically relevant to ageing biology [4], [5], [14].
- What remains unproven is much broader: NAD therapy has not been shown to reverse human ageing, extend human lifespan, or reliably produce visible rejuvenation. Longevity claims should be treated as mechanistic or preliminary unless supported by well-designed long-term human trials [5], [14].
