Why?
You see, statins work in the liver by blocking an enzyme pathway that leads to the creation of cholesterol. Unfortunately, that same enzyme pathway is the one your body uses to create CoQ10. So statin takers need to be especially aware of the fact that theyre not producing CoQ10 at the levels they would be if they were taking no medication. When your body lacks CoQ10, energy production will lag and cell function will suffer.
The pathway that statins inhibit is also one that produces CoQ10 in the body. When you block both bad things happen long term.
One thing your heart uses is CoQ10. IIRC it uses more than any other organ.
