What Are the Risks of Taking CoQ10?

CoQ10 is a naturally occurring compound made in the body. It is used as a food supplement for its antioxidant properties and to help treat cardiovascular disease. It is used to neutralize free radicals associated with cancer and may help improve the body's immune system. Studies have shown few side effects of taking CoQ10, but risks may exist for some people when taking this compound.

Insomnia

• According to the National Cancer Institute, though risks of taking CoQ10 are minimal, some people do experience side effects. One of those side effects is insomnia, a condition that keeps you from falling asleep or causes difficulty in going to sleep.

Nausea

• Some people may experience nausea when taking CoQ10, which promotes a feeling of queasiness or an upset stomach. You may feel a discomfort or a sickness in the stomach that is accompanied by an urge to vomit.

Rash

• CoQ10 may cause a rash. A rash may appear as a red blotch or patch upon the skin or give a flushed rosy look to certain areas of the body. This may indicate an allergic reaction of some type in the use of this compound and it is advised to contact your doctor.

Dizziness

• Light-headedness or dizziness may occur for some people when taking CoQ10. This may also cause a feeling of tiredness, irritability, a headache, a sensitivity to light or heartburn. Upper abdominal pain may be present as well.

Gastrointestinal Distress

• Because CoQ10 is not a drug, it is not regulated by the Food and Drug Administration so there are no recommended daily dosages. It is considered a food supplement and oftentimes people think that if one pill works, two or more may be better. Some people have experienced abdominal pain and other related gastrointestinal distress when taking excessive amounts of CoQ10.

Prescribed Medications and CoQ10

• Not enough studies have been done to determine all the risks of taking CoQ10. Always check with your doctor about taking any food supplements, vitamins or other non-regulated compounds like CoQ10. Prescribed medications, vitamins and food supplements may have hidden dangers when combined together.
