CoQ10 Supports Lipid Metabolism, Glycemic Control, Healthy Inflammatory Response
A systematic review and meta-analysis of controlled clinical trials found significant improvement in blood levels of lipids, including cholesterol and triglycerides; glycemic control, including glucose, insulin, insulin resistance and hemoglobin A1c; and markers of inflammation, including C-reactive protein (CRP), tumor-necrosis factor-alpha and interleukin-6 in participants who received coenzyme Q10.
"Abnormal lipid and glycemic metabolism is closely linked to the occurrence and development of various metabolic diseases, including dyslipidemia, diabetes, coronary artery disease, and metabolic syndrome, and poses a significant global health burden," the authors remarked. "Importantly, disturbances in lipid and glucose metabolism are interrelated and may exacerbate one another."
On average, trial participants who received CoQ10 had significant reductions in serum triglycerides, total cholesterol and low-density lipoprotein (LDL) cholesterol in addition to a significant increase in beneficial high-density lipoprotein (HDL) cholesterol. Evaluation of markers of glucose metabolism found significant reductions in hemoglobin A1c (a marker of long-term glucose control), fasting glucose, fasting insulin and insulin resistance. When inflammatory markers were examined, trial participants who received CoQ10 experienced significant reductions in CRP, tumor-necrosis factor-alpha and interleukin-6.
The meta-analysis included 64 randomized, controlled trials that enrolled a total of 3,422 individuals, including 1,721 participants who received CoQ10 and 1,701 members of the control groups. Participants included men and women with diabetes, metabolic syndrome, unhealthy lipids, coronary artery disease, polycystic ovary syndrome, statin-related muscle pain and related metabolic disorders. Coenzyme Q10 doses ranged from 60 mg to 600 mg per day, given for 4 to 24 weeks. Several trials evaluated CoQ10 combined with other medical or nutritional therapies. The findings were published May 26, 2026, in the Journal of Diabetes Research.1
"This meta-analysis demonstrates that CoQ10…exerts beneficial effects on lipid metabolism, glycemic control, and inflammatory biomarkers among individuals with metabolic disorders," the authors concluded.

Apply What You’ve Learned: Coenzyme Q10 (CoQ10)
- Coenzyme Q10 is an antioxidant molecule that participates in the production of energy within our cells’ “power plants” that are known as mitochondria. Coenzyme Q10 is made in the body, but the amount produced declines during aging.2
- Coenzyme Q10 has been shown to support cardiovascular health as well as kidney, liver and muscle function.3 Its energy-supportive properties may help improve fatigue.4
- Coenzyme Q10 has two forms: an oxidized form known as ubiquinone and a reduced, active form known as ubiquinol. This active form of CoQ10 has superior bioavailability compared with ubiquinone.
- However, a recent innovation designed to enhance ubiquinone bioavailability with the addition of galactomannan fibers to boost absorption resulted in up to 24 times more bioavailability in comparison with an equal amount of standard ubiquinone and up to three times greater bioavailability compared with ubiquinol.5
