Q: I am managing to control my blood pressure by using RESPeRATE and taking supplements. One supplement I take is COQ10. I also take a low dose aspirin daily as a blood thinner to protect against stroke. I recently learned that COQ10 also has the effect of thinning the blood. Should I be concerned about taking both aspirin and COQ10?
A: You should only be taking aspirin if it has been recommended by your doctor. There is a real risk of serious bleeding with long term aspirin so only certain people benefit from taking aspirin. It is not clear that Coenzyme Q10 is associated with an increased risk of bleeding. I suggest you make an appointment with your doctor to fully understand your risk for heart disease and determine the best preventive measures. For more information about side effects of Coenzyme Q10 go to this page on the U.S. National Library of Medicine site.
