First-line treatments
Creatine Monohydrate
Creatine supports cellular energy buffering by maintaining ATP levels. May help muscles and tissues with high energy demands cope with impaired oxidative phosphorylation.
Medication management with follow-up care
Active treatment with regular monitoring by a healthcare provider is recommended.
Respiratory Muscle Training
Targeted exercises to maintain respiratory muscle strength, as complex I deficiency can affect diaphragmatic and intercostal muscle function over time.
Additional treatment options
Alpha-Lipoic Acid
A potent antioxidant that supports mitochondrial energy metabolism and helps neutralize reactive oxygen species produced by dysfunctional complex I.
medicationAnti-Inflammatory Mediterranean-Style Diet
Emphasis on omega-3 fatty acids, olive oil, vegetables, and fish while reducing inflammatory foods. May help mitigate systemic inflammation associated with mitochondrial dysfunction.
dietaryNeurodevelopmental Assessment
Regular neurological and developmental evaluations to track cognitive and motor progression, enabling early intervention with speech, occupational, or physical therapy.
