WARNING: DISCLAIMER: The below uses are based on tradition, scientific theories, or limited research. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses that are not listed below.
Abnormal heart rhythms, amyotrophic lateral sclerosis (ALS), anemia, antioxidant, Bell's palsy, breathing difficulties, cerebellar ataxia, chronic obstructive pulmonary disease (COPD), cognitive performance, deafness, fibromyalgia, gingivitis, hair loss (and hair loss from chemotherapy), hepatitis B, high cholesterol, immune system diseases, infertility, insomnia, ischemia, leg swelling (edema), life extension, liver enlargement or disease, lung disease, MELAS syndrome (mitochondrial myopathy, encephalopathy, lactacidosis, stroke), multiple sclerosis, muscle wasting, neurodegenerative disorders, nutrition, obesity, Papillon-Lefevre Syndrome, physical performance, psychiatric disorders, reduction of phenothiazine drug side effects, reduction of tricyclic antidepressant (TCA) drug side effects, speech disorders (Landau-Kleffner syndrome), stomach ulcer.


Adults (above 18 years old)

50-1,200 milligrams of CoQ10 have been taken in divided doses by mouth daily.

85 milligrams of CoQ10 per milliliter of soybean oil suspension has been applied to the surface of affected areas once weekly using a plastic syringe for gum disease.

Most studies of CoQ10 for heart protection during bypass surgery have used CoQ10 taken by mouth. One study used intravenous CoQ10, 5 milligrams per kilogram of body weight, given two hours prior to surgery. Safety is not clear. Any therapies used close to the time of surgery should be discussed with the surgeon and a pharmacist prior to starting.

Children (under 18 years old)

There is not enough scientific information to recommend the safe use of CoQ10 in children. A qualified healthcare provider should be consulted before considering use.


DISCLAIMER: Many complementary techniques are practiced by healthcare professionals with formal training, in accordance with the standards of national organizations. However, this is not universally the case, and adverse effects are possible. Due to limited research, in some cases only limited safety information is available.


In theory, allergic reactions to supplements containing CoQ10 may occur. Itching or rash has been reported.

Side Effects and Warnings

There are few serious reported side effects of CoQ10. Side effects are typically mild and brief, stopping without any treatment needed. Reactions may include nausea, vomiting, stomach upset, heartburn, diarrhea, loss of appetite, skin itching, rash, insomnia, headache, dizziness, itching, irritability, increased light sensitivity of the eyes, fatigue, or flu-like symptoms.

CoQ10 may lower blood sugar levels. Caution is advised in patients with diabetes or hypoglycemia, and in those taking drugs, herbs, or supplements that affect blood sugar. Serum glucose levels may need to be monitored by a healthcare provider, and medication adjustments may be necessary.

Low blood platelet number was reported in one person taking CoQ10. However, other factors (viral infection, other medications) may have been responsible. Lowering of platelets may increase the risk of bruising or bleeding, although there is a lack of known reports of bleeding from CoQ10. Caution is advised in people who have bleeding disorders or who are taking drugs that increase the risk of bleeding. Dosing adjustments may be necessary.

CoQ10 may decrease blood pressure, and caution is advised in patients with low blood pressure or taking blood pressure medications. Elevations of liver enzymes have been reported rarely, and caution is advised in people with liver disease or taking medications that may harm the liver. CoQ10 may lower blood levels of cholesterol or triglycerides. Thyroid hormone levels may be altered based on one study.

Organ damage due to lack of oxygen/blood flow during intense exercise has been reported in a study of patients with heart disease, although the specific role of CoQ10 is not clear. Vigorous exercise is often discouraged in people using CoQ10 supplements.

Pregnancy and Breastfeeding

There is not enough scientific evidence to support the safe use of CoQ10 during pregnancy or breastfeeding. Sperm may be affected.
