Chronic fatigue often has its roots at the cellular level. Mitochondria—the powerhouses in every cell—produce ATP, the energy currency of life. When they're compromised, everything suffers.
Signs of Mitochondrial Dysfunction
- Crushing fatigue not relieved by rest
- Exercise intolerance and slow recovery
- Brain fog and cognitive decline
- Muscle weakness and pain
- Sensitivity to environmental factors
Supporting Mitochondrial Health
Key nutrients include CoQ10, PQQ, NAD+ precursors, magnesium, and B vitamins. Reducing oxidative stress, supporting detoxification, and addressing chronic infections also optimize mitochondrial function. HPA axis dysfunction often amplifies mitochondrial fatigue—read our guide on cortisol and the stress response.
