Electron carrier in mitochondrial complexes I, II, and III — essential for ATP synthesis. Potent lipid-soluble antioxidant in cell membranes. Ubiquinol (reduced form) is the active antioxidant; ubiquinone (oxidized) requires conversion. Membrane stabilizer.
Studies have administered: 100–400mg/day typical research range; higher doses (600–1200mg/day) in specific conditions
Q-SYMBIO trial: 300mg/day CoQ10 reduced major CV events 43% in heart failure patients. Multiple statin myopathy studies mixed but trending beneficial. Mitochondrial disease: well-established. K-PACT trial and others ongoing.
Excellent safety profile across decades of study; mild GI at high doses; may lower blood pressure requiring monitoring
