Coenzyme Q-10, also known as CoQ10, is a compound similar to vitamins that your body naturally produces. CoQ10 supplements are possibly beneficial for many health conditions including high blood pressure and heart disease. Because CoQ10 is not a medication regulated by the FDA, there is no official dose of CoQ10. Recommended doses generally range from 100 to 300 milligrams per day, although the exact dose you should take depends on the reason you are taking it. Talk to your doctor before taking this supplement.

High Blood Pressure

Treating high blood pressure is a common reason to take CoQ10. High blood pressure is often treated with a range of CoQ10 doses, from 120 to 200 milligrams per day, divided into two doses. If only your systolic blood pressure -- the top number on your blood pressure reading -- is elevated, the dose is usually closer to 120 mg per day, split into two doses, according to MedlinePlus.

Heart Disease

Another common use of CoQ10 is treating heart disease. If you have already had one heart attack, taking 120 milligrams of CoQ10 per day, divided into two doses, may decrease the risk of a second heart attack. For general prevention of heart failure, a slightly smaller dose of 100 milligrams per day, split into 2 or 3 doses, is usually recommended, MedlinePlus reports.

Other Diseases

CoQ10 is not considered a treatment for any type of disease, however it may be prescribed as part of treatment to help reduce symptoms in certain conditions. Parkinson's disease is sometimes treated with very large doses of CoQ10, up to 3,000 milligrams per day, split into 3 or 4 doses, reports the Linus Pauling Institute. Muscular dystrophy and pre-eclampsia are generally treated with a dose of 100 milligrams per day. Certain mitochondrial disorders, such as mitochondrial encephalomyopathies, may be treated with 150 to 160 milligrams per day, although in certain cases, doses up to 3,000 milligrams per day may be used.

Additional Uses

If you are diagnosed with a CoQ10 deficiency, you doctor may recommend taking a single dose of 150 milligrams daily. To prevent migraine headaches, the recommended dose is 300 milligrams each day, divided into three doses. Male infertility may be treated with daily doses of 200 to 300 milligrams per day.
