Pyrroloquinoline Quinone (PQQ) for ALS
Also known as: PQQ, BioPQQ, Methoxatin
PQQ promotes mitochondrial biogenesis — generating new mitochondria to replace dysfunctional ones in ALS motor neurons.
Mechanism of Action
PQQ activates PGC-1α through CREB phosphorylation, stimulating mitochondrial biogenesis. It acts as a redox cycling antioxidant (20,000+ cycles vs 4 for vitamin C), protects mitochondrial Complex I, and activates NGF signaling for motor neuron support.
General mechanism: Redox cycling cofactor. PGC-1α/CREB activator for mitochondrial biogenesis. NGF stimulator. Antioxidant (20,000+ redox cycles).
Current Evidence
Preclinical evidence for neuroprotection. Human studies show improved mitochondrial function markers. No ALS-specific trials.
Clinical Status: Available as supplement. No ALS trials. Mitochondrial biogenesis mechanism well-characterized.
Safety Profile
Very safe. Present in foods (kiwi, parsley). Well-tolerated as supplement. No significant side effects.
Key Research Questions
- Can PQQ generate sufficient new mitochondria to rescue ALS motor neurons?
- Does PQQ combination with CoQ10 and NR provide comprehensive mitochondrial support?
