What is the evidence in favor of supplementary Coenzyme Q10 for individuals with metabolic disorders?

Metabolic disorders such as diabetes

Metabolic disorders affect how the body converts food into energy and how it processes sugars, fats, and proteins. CoQ10 supplementation helps against disorders of glucose metabolism and lipid metabolism.

A 2026 systemic review and meta-analysis shows that supplementation with Coenzyme Q10 (CoQ10) improves metabolic health in individuals with the following disorders [Zhang 2026]:

  • abnormal lipid metabolism
  • impaired glucose regulation
  • chronic systemic inflammation

The authors of the review evaluated 64 randomized controlled trials involving 3,422 participants. Notably, the 64 RCTs investigated CoQ10 supplementation in a range of metabolic disorders [Zhang 2026]:

What did the CoQ10 and metabolic disorders studies show?

Improvements in blood lipid profiles

Compared with control groups, the CoQ10 treatment groups had modest but statistically significant improvements in lipid profiles [Zhang 2026].

  • reduction in triglyceride levels
  • reduction in total cholesterol levels
  • reduction in LDL cholesterol levels
  • increases in HDL cholesterol levels

Improvements in glycemic control

Here, compared with control groups, the CoQ10 treatment groups had meaningful improvements in glycemic control [Zhang 2026].

  • lower fasting blood glucose by roughly 10 mg/dL
  • reduced glycated hemoglobin (HbA1c) by 0.22 percentage points
  • decreased fasting insulin levels
  • improved insulin resistance as measured by HOMA-IR

Improvement in chronic systemic inflammation

Again, compared with control groups, the CoQ10 treatment groups had several significantly reduced inflammatory biomarkers [Zhang 2026].

  • decreased levels of C-reactive protein (CRP)
  • decreased levels of tumor necrosis factor-alpha (TNF-α)
  • decreased levels of interleukin-6 (IL-6)

Conclusion: CoQ10 Supplementation and Metabolic Disorders

CoQ10 supplementation is a useful adjunctive treatment to reduce cardiovascular disease risk and to improve metabolic health.

Firstly, CoQ10 supplementation improves blood lipid profiles.

Secondly, CoQ10 supplementation enhances glucose metabolism and insulin sensitivity in individuals with metabolic disorders.

Thirdly, CoQ10’s antioxidant and anti-inflammatory properties help counteract the chronic low-grade inflammation seen in obesity, diabetes, and related conditions.

Finally, CoQ10 supplementation helps restore CoQ10 levels, improves cellular metabolism, and reduces inflammatory signaling.
