Coenzyme Q10 is a compound your body naturally produces in small amounts. It is also found in certain types of food, including seafood and meat. Doctors use supplements containing coenzyme Q10 to treat a variety of health conditions, including heart disease and Parkinson's disease. The optimal dose of coenzyme Q10 depends on the reason you are taking it and usually ranges between 100 and 300 mg per day. As with any health supplement, consult your doctor before taking coenzyme Q10.
Deficiency
If you are diagnosed with a coenzyme Q10 deficiency, your doctor will most likely prescribe a dose of 150 mg of coenzyme Q10 per day. Coenzyme Q10 is soluble in fat molecules, which means taking the supplements with a meal that contains fat will help increase its absorption.
Heart Disease
Coenzyme Q10 supplements may reduce several risks associated with heart disease. To reduce the risk of sudden heart failure, MedlinePlus recommends 100 mg per day, divided into two or three doses each day. If you have already had one heart attack, taking 120 mg per day divided into two doses may reduce the risk of subsequent heart attacks.
High Blood Pressure
High blood pressure might also be treated with coenzyme Q10 supplements. Doses ranging from 120 to 200 mg per day, split into two doses, are often used to lower blood pressure, MedlinePlus reports. If only your systolic blood pressure is high, the recommended dose is 120 mg per day, split into two doses.
Other Diseases
A dose of 200 mg per day is recommended to treat HIV/AIDS, MedlinePlus explains. Muscular dystrophy is often treated with a single dose of 100 mg per day. For treating Parkinson's disease, a wide range of doses have been used, ranging from 300 mg per day up to 2,400 mg per day, split into three or four doses. Take doses this high only under the supervision of a qualified health care provider.
Other Uses
Coenzyme Q10 may be taken for male infertility, which is usually treated with a dose of 200 to 300 mg per day. Three doses of 100 mg each day may decrease the incidence of migraine headaches. Certain mitochondrial disorders, such as mitochondrial encephalomyopathies, are often treated with 150 to 160 mg per day.
