Researchers believe CoQ10 has the potential to reduce blood pressure without causing significant side effects, notes the University of Maryland Medical Center. As of 2015, however, there have been no large-scale studies to determine the effects of CoQ10 on blood pressure.
As of 2015, several small studies have shown that CoQ10 reduces blood pressure, states the University of Maryland Medical Center. One studied showed that CoQ10 may reduce diastolic blood pressure by 10 millimeters of mercury and systolic blood pressure by 17 millimeters of mercury. More research is needed to determine if CoQ10 has the same benefits in larger groups of people. People with high blood pressure should seek advice from a medical professional before trying CoQ10 to treat hypertension.
