CoQ10 or Coenzyme Q is also known as ubiquinone and is a coenzyme common in human beings, animals and most bacteria. It is an antioxidant that your body produces naturally. Your cells use CoQ10 for growth and maintenance. Levels of CoQ10 in your body decrease as you age. CoQ10 levels have also been found to be lower in people with certain conditions, such as heart disease.

Symptoms of deficiency include neurological abnormalities that can occur in primary coenzyme Q10 deficiency include seizures, intellectual disability, poor muscle tone (hypotonia), involuntary muscle contractions (dystonia), progressive muscle stiffness (spasticity), abnormal eye movements (nystagmus) and vision loss caused by degeneration.

You can take CoQ10 through foods and supplements. Food sources include organ meats such as the heart, liver and kidney of animals; muscle meats such as pork, beef and chicken; fatty fish such as trout, herring, mackerel and sardine; vegetables such as spinach, cauliflower and broccoli; fruit such as oranges and strawberries; legumes such as soybeans, lentils and peanuts; and nuts and seeds such as sesame seeds and pistachios.

Taking Coenzyme Q10 supplements is most commonly used for conditions that affect the heart such as heart failure and fluid build up in the body (congestive heart failure or CHF), chest pain (angina), and high blood pressure. It is also used for preventing migraine headache, Parkinson disease, and many other conditions. Coenzyme Q10 (CoQ10) has been linked to improved ageing, exercise performance, heart health, diabetes, fertility and migraines. It may also counteract the adverse effects of statin medications. Typically, 90–200 mg of CoQ10 per day are recommended, though some conditions may require higher dosages of 300–600 mg.
