Test Details

Coenzyme Q10 (CoQ10)

Coenzyme Q10 (CoQ10), also known as ubiquinone, is an endogenously produced lipid-soluble cofactor that has a significant role in the formation of energy within cells. It also serves as a potent antioxidant and is very effective in inhibiting the oxidation and modification of low density lipoproteins (LDLs).

Clinical Significance

Clinical Significance

Coenzyme Q10 (CoQ10)

Studies have shown that statins reduce serum CoQ10 levels. Low CoQ10 levels are associated with increased risk of statin associated muscle pain and heart failure. Supplementation decreases muscle symptoms related to statins and mortality in patients with heart failure. Early recognition of CoQ10 deficiency is essential to institute appropriate and timely treatment for cardiovascular disease.

Significant CoQ10 deficiency has been associated with:1-4

  • Cardiovascular disease
  • Congestive heart failure
  • Significant muscle disorders
  • Significant neurological disorders
  • Liver disease
  • Chronic kidney failure
