Coenzyme Q10 is a fat-soluble antioxidant produced by the body and obtained in small amounts from food, essential for mitochondrial energy production in every cell.
CoQ10 levels decline with age and are depleted by statin medications, which block the same pathway that produces cholesterol and CoQ10. Low levels may contribute to fatigue, muscle pain, and cardiovascular dysfunction. Testing is most relevant for people on statins or with unexplained fatigue.
Optimal Coenzyme Q10: 1-2 µg/mL.
Typically re-tested every 16 weeks.
