Coenzyme Q10: migraine, statin pain and safety

What is CoQ10?

Coenzyme Q10 is a substance naturally present in the body and involved in cellular energy production. It is also sold as a supplement, including as ubiquinone or ubiquinol. A role in normal cell function does not prove that taking extra CoQ10 improves energy or treats a particular disease.1

Does CoQ10 help statin-related muscle pain?

Studies have reported different results. In a 2015 US study, 120 people with previous muscle symptoms underwent a blinded comparison of a statin and placebo; 41 who reported pain on the statin but not placebo were then assigned CoQ10 or placebo with simvastatin. The researchers found no significant reduction in pain with CoQ10 in that small group. A separate 2014 study of 50 people reporting muscle symptoms while taking statins found improvements in pain scores with CoQ10 over 30 days. The participants, methods and products differed, and neither short study settles every situation. The US National Center for Complementary and Integrative Health says the overall evidence does not support CoQ10 for statin muscle pain.231

Can CoQ10 help prevent migraine attacks?

There is a possible benefit, but the evidence remains uncertain and does not show that every product will help. In a 2005 double-blind trial, 42 adults with migraine were assigned a particular liquid CoQ10 preparation or placebo for three months. The researchers reported that 47.6% in the CoQ10 group and 14.4% in the placebo group had at least a halving of attack frequency. This small, short trial cannot predict an individual response or establish long-term safety. MSE Pharmazeutika supported the study and supplied both products; one author reported honoraria from the sponsor. The US NCCIH says a 2021 review of six studies suggested reduced migraine frequency and duration, but not severity, with small effects and remaining uncertainty. CoQ10 is not interchangeable with prescribed migraine treatment, and it can interact with medicines including warfarin and insulin. Discuss persistent or changing headaches and any specific supplement with a clinician. For another nutrient studied for migraine, see vitamin B2 and migraine.45

A suddenly extremely painful headache, new weakness on one side or difficulty speaking needs emergency help immediately. Do not assume these symptoms are a usual migraine or wait for a supplement to work.6

What about heart health or energy?

CoQ10 is studied for heart failure and other cardiovascular questions, but the US NIH summary describes the evidence for heart failure and preventing heart disease as inconclusive. A trial in a particular condition cannot establish benefit for general tiredness or replace proven treatment. Persistent fatigue or muscle pain can have many causes and deserves assessment.1

Safety and medicine interactions

Digestive upset and difficulty sleeping can occur. CoQ10 may interact with warfarin, insulin and some cancer treatments; the exact medicine and circumstances matter. Tell a pharmacist or clinician about supplements and medicines before making changes, and do not stop a prescribed statin on your own. See supplement and medicine interactions and how to read a label.1
