Why Statins May Require You Take Extra CoQ10 and Vitamin E

Statins are drugs used to lower cholesterol by blocking cholesterol synthesis in the liver (1). By lowering total and LDL cholesterol, in effect, they help lower risk of heart disease and death (1). The most commonly known statin drugs are simvastatin (Zocor), lovastatin (Mevacor), pravastatin (Pravachol), and rosuvastatin (Crestor).

Currently, it is theorized that as statins block cholesterol synthesis, they also block synthesis of coenzyme Q10 (2). This is unfortunate because coenzyme Q10 plays a key role in the mitochondria in the electron transport chain, as an antioxidant and as a regenerator of vitamin E (3).

Statin therapy, then, could potentially lead to deficiencies of both coenzyme Q10 and, possibly, increase the need for vitamin E in cells (4). It has been theorized that deficiencies in both coenzyme Q10 and vitamin E are why statins cause statin-related muscle pain and statin-related myopathy (3-4).
