Also known as: Ubiquinone, Ubiquinol
CoQ10 is a vital cofactor in mitochondrial energy production and a powerful lipid-soluble antioxidant. It supports heart health, cellular energy, and is especially important for statin users whose CoQ10 levels are depleted.
Coenzyme Q10 (CoQ10) is a naturally occurring quinone compound found in virtually every cell of the body, with the highest concentrations in the heart, liver, kidneys, and pancreas. It plays a dual role as an essential electron carrier in the mitochondrial electron transport chain (complexes I–III) and as a potent lipid-soluble antioxidant protecting cell membranes from peroxidation. CoQ10 exists in two interconvertible forms: ubiquinone (oxidized) and ubiquinol (reduced, active form). Endogenous production declines with age, and statin medications further deplete CoQ10 by inhibiting the mevalonate pathway shared with cholesterol synthesis. Clinical evidence strongly supports CoQ10 supplementation for heart failure management, statin-associated myopathy, blood pressure reduction, and mitochondrial disorders.
The Q-SYMBIO trial demonstrated that 300 mg CoQ10 daily for 2 years reduced major adverse cardiovascular events by 43% in chronic heart failure patients.
Statins inhibit CoQ10 synthesis by 40%. Supplementation with 100–200 mg daily can reduce statin-associated myalgia by 40% in affected patients.
Meta-analyses suggest CoQ10 supplementation can reduce systolic blood pressure by 11 mmHg and diastolic by 7 mmHg.
With a fat-containing meal
CoQ10 is fat-soluble; absorption increases 3-fold with dietary fat.
Split into 2–3 doses with meals
The Q-SYMBIO trial used 300 mg daily (100 mg three times daily).
Adults over 40 and those with absorption difficulties
