- MOTS-c
- AMPK activation → NAMPT upregulation
- Mitochondrial NAD+ synthesis
- Metabolic aging, exercise capacity, mitochondrial dysfunction models
- 25–40% increase in mitochondrial NAD+/NADH ratio
- Best first-line choice for age-related NAD synthesis decline. Works upstream of precursor availability
- Humanin analogs
- Cytoprotective signaling → reduced sirtuin overactivation
- Cytoplasmic and nuclear NAD+ conservation
- Oxidative stress models, neurodegeneration, ischemia-reperfusion
- 20–30% reduction in stress-induced NAD consumption
- Most effective when NAD depletion is driven by inflammatory or oxidative stress rather than synthesis failure
- Epithalon
- Circadian clock restoration → NAMPT oscillation
- Circadian-regulated NAD pools (all compartments)
- Aging models with circadian disruption, sleep deprivation models
- 40–50% restoration of peak NAD amplitude (not baseline)
- Requires time-course sampling to detect effect. Single-timepoint measurements will miss the mechanism entirely
