Statins are the most profitable drugs in history. They are (over) prescribed to lower total cholesterol, based on the unproven idea that elevated cholesterol causes heart disease. This has been repeated so long and so loud that everyone takes it as an established fact.

One of several known side effect of statins is that they reduce the level of Coenzyme Q10, an essential enzyme that is required for a healthy heart.
