There are no well-accepted treatments for mitochondrial diseases. Most experts, however, use a combination of vitamins, optimize the patient’s general health, and attempt to prevent worsening of symptoms during times of illness and stress. The mainstays of the pharmacological treatment for mitochondrial diseases are coenzyme Q10 (CoQ10), a compound found in all cells that participates in mitochondrial energy production; and antioxidants, such as vitamin C and vitamin E, which could reduce the cell damage from inefficient mitochondria. Other compounds also used to treat patients with mitochondrial diseases include L-creatine, L-arginine, and L-carnitine, all of which can be purchased over the counter at most health food stores. At the very least this mitochondrial cocktail is likely harmless, and may ameliorate many of the symptoms of mitochondrial dysfunction, including muscle weakness and fatigue.
