CoQ10 has not been shown to be of value in treating cancer, but it may reduce the risk of heart damage caused by one type of cancer chemotherapy drug.
Only a few studies have looked at whether CoQ10 might help prevent heart disease, and their results are inconclusive. Research on the effects of CoQ10 in heart failure is also inconclusive. However, there is evidence that CoQ10 may reduce the risk of some complications of heart surgery.
Although results of individual studies have varied, the overall scientific evidence does not support the idea that CoQ10 can reduce muscle pain caused by the cholesterol-lowering drugs known as statins. The small amount of evidence available suggests that CoQ10 probably doesn’t have a meaningful effect on blood pressure.
Guidelines from the American Academy of Neurology and the American Headache Society say CoQ10 is “possibly effective” in preventing migraines, but this conclusion is based on limited evidence.

The dosage varies depending on age and what it is being used for. Be sure to follow relevant directions on product labels, and consult your pharmacist, physician or other healthcare professional before using.
No serious side effects of CoQ10 have been reported. Mild side effects such as insomnia or digestive upsets may occur. CoQ10 may interact with the anticoagulant (blood thinner) warfarin and the diabetes drug insulin, and it may not be compatible with some types of cancer treatment.
› Dietary supplements
CoQ10 supplements are most commonly available as softgels.
