Our objective was to review all published trials of coenzyme Q10 for hypertension, assess overall efficacy and consistency of therapeutic action and side effect incidence. Meta-analysis was performed in 12 clinical trials (362 patients) comprising three randomized controlled trials, one crossover study and eight open label studies. In the randomized controlled trials (n=120), systolic blood pressure in the treatment group was 167.7 (95% confidence interval, CI: 163.7-171.1) mm Hg before, and 151.1 (147.1-155.1) mm Hg after treatment, a decrease of 16.6 (12.6-20.6, P<0.001) mm Hg, with no significant change in the placebo group. Diastolic blood pressure in the treatment group was 103 (101-105) mm Hg before, and 94.8 (92.8-96.8) mm Hg after treatment, a decrease of 8.2 (6.2-10.2, P<0.001) mm Hg, with no significant change in the placebo group. In the crossover study (n=18), systolic blood pressure decreased by 11 mm Hg and diastolic blood pressure by 8 mm Hg (P<0.001) with no significant change with placebo. In the open label studies (n=214), mean systolic blood pressure was 162 (158.4-165.7) mm Hg before, and 148.6 (145-152.2) mm Hg after treatment, a decrease of 13.5 (9.8-17.1, P<0.001) mm Hg. Mean diastolic blood pressure was 97.1 (95.2-99.1) mm Hg before, and 86.8 (84.9-88.8) mm Hg after treatment, a decrease of 10.3 (8.4-12.3, P<0.001) mm Hg. We conclude that coenzyme Q10 has the potential in hypertensive patients to lower systolic blood pressure by up to 17 mm Hg and diastolic blood pressure by up to 10 mm Hg without significant side effects.
