“Does CoQ10 have any potentially dangerous side effects?” is the first and most important question that you should consider before taking CoQ10. Some people may find it a waste of time, but it’s still an important question to ask. You wouldn’t start taking a new drug without learning anything about it, so keep in mind that nutritional supplements are also medicine and should be researched ahead of time. Before you start any new medication or supplement, learning about the possible side-effects and drug interactions is one of the most important parts of preparing.
It usually takes very high doses of CoQ10 before most people start reporting the development of side-effects. And since most people who are taking CoQ10 for health reasons will be taking much lower doses than those that are commonly associated with such side effects, you are unlikely to notice much if you are not involved in some sort of research that requires you to take a very high dose. In research studies involving high doses of CoQ10, usually in excess of 1000 mg, the subjects who develop side effects tend to suffer from mild rashes, irritability, and stomach pain. Unless you are actually involved in one of these studies, you will never end up taking a dose this high. That does not mean that there are no side effects when you are taking lower doses, though, such as insomnia, fatigue, or heartburn.
If you are taking any other medications, it is important that you find out whether or not they are going to interact with CoQ10 at all before you start taking it. The problem with adding another drug to your treatment is that it might interact with another drug that you are already taking. Some medications can potentially do damage to the body, such as some forms of beta blockers and chemotherapy medications. Taking CoQ10 along with these drugs help to protect your heart from the damage they can do. Blood thinners provide another example as a potential interaction; when CoQ10 is taken at the same time as blood thinners, the effectiveness of the blood thinners is significantly reduced. Before you do anything that can potentially have a serious effect on your health or body, be sure that you have a long talk with your doctor about what to expect.
CoQ10 supplements, according to current research, have very few side effects, and the side effects that they do have are very mild. The risk of drug interactions means that you need to be sure to discuss CoQ10 with your doctor before you actually start taking it. Still, the potential ways that CoQ10 benefits people who have high blood pressure make that consultation more than worth it, as CoQ10 is one of the worst kept health secrets that too few people know about..
