CoQ10 (Coenzyme Q10 (Ubiquinol))
A fat-soluble electron carrier essential for mitochondrial ATP production. The reduced form (ubiquinol) is the body's most potent lipid-soluble antioxidant. Critical for cardiac function, statin users, and aging-related energy decline.
How it works
Shuttles electrons in the mitochondrial respiratory chain (Complex I→III). As ubiquinol, neutralizes lipid peroxyl radicals protecting cell membranes and LDL from oxidation. Restores mitochondrial membrane potential.
Key facts
- Molecular weight: 863.34 Da
- Half-life: ~33 hours (ubiquinol)
- Bioavailability: ~6-9% (standard); ~300% improved with ubiquinol/lipid formulations
- Storage: Room temperature. Protect from light and heat.
Dosing overview
- Typical dose: 100-300 mg ubiquinol
- Frequency: Daily with fat-containing meal
- Duration: Ongoing
- Route: Oral softgel
Reported benefits

Research
- Q-SYMBIO trial: CoQ10 and heart failure (2020): Long-term CoQ10 (300mg/day) reduced cardiovascular mortality by 43% and hospitalization by 50% in chronic heart failure patients.
- Ubiquinol and statin myopathy (2021): 200mg ubiquinol reduced statin-induced muscle pain by 53% and improved mitochondrial function markers in statin-intolerant patients.
