I take CoQ10. Been taking it for several years now as I understand it's good for the heart. I don't take a high dose of it, just 100 mg per day becasue I do eat fairly good food sources of it too: http://www.livestrong.com/article/256149-what-foods-are-rich-in-coq10/ My cardiologist and other docs know I take it and when I had AVR the hosiptal nursing staff knew I was taking it - they added my supplemental CoQ10 to my daily meds handed out to me each day. I don't take aspirin.
