Coenzyme Q10 (CoQ10) appears to be safe to take with statins. But you should always use caution when taking dietary supplements.
Some experts think taking CoQ10 as a supplement can prevent muscle cell damage. This is a problem some people have when they take statins. Some studies show CoQ10 may lower this risk. Others say the effect on muscle symptoms is small at best.
There have been no published reports of problems in people taking statins and CoQ10 together. It also appears there are few harmful effects of taking CoQ10, supplements in general. However, dietary supplements and herbal remedies aren’t regulated the way other medicines are. That means they can be sold without proven effectiveness. It also means they are not tested for safety. In fact, some may not actually contain what the label claims. It is best to talk to your doctor before you take herbs or supplements.
Just to be safe, tell your doctor what you take!
