Researchers studied the effects of CoQ10 supplementation on patients who were identified by cardiac catheterization as having at least 50 percent blockage of one major coronary artery, and had been treated with statins, who were enrolled in the study.

Subjects were randomly assigned to either the placebo or CoQ10 group, and scientists monitored CoQ10, antioxidant, and inflammatory markers.

The study, which was published in Nutrition Journal, lasted 12 weeks.

In the CoQ10-supplemented group, levels of CoQ10 and antioxidant enzyme activities were significantly higher than the non-supplemented group.

Furthermore, the levels of inflammatory markers were significantly lower after CoQ10 supplementation.

The authors concluded, “Coenzyme Q10 supplementation at 300 mg/day significantly enhances antioxidant enzyme activities and lowers inflammation in patients who have coronary artery disease during statin therapy.”

Statins are known to interfere with the body’s production of CoQ10, which is responsible for a wide range of positive effects which include reducing the risk of coronary artery disease and treating congestive heart failure.

Anyone taking a statin medication should supplement with CoQ10. A better choice might be to take the CoQ10 and avoid the statin medication.
