Full Answer

CoQ10 is a coenzyme found and manufactured in every cell of the body that helps to produce energy for the growth and maintenance of cells. The substance also functions as an antioxidant, helping to protect the body against harmful free radicals. Small amounts of CoQ10 are found in many types of food, but beef, organ meats, soy oil, peanuts and sardines have particularly high levels of the coenzyme. Mild insomnia has been observed in individuals who take more than 100 milligrams of CoQ10 every day, and those who take 300 milligrams or more per day for an extended periods may have elevated levels of liver enzymes according to WebMD.

CoQ10 supplements are safe for most adults, but side effects may include nausea, vomiting, loss of appetite, upset stomach and diarrhea. Children should only take CoQ10 under close medical supervision. Individuals with abnormal blood pressure, patients who have recently had surgery and women who are pregnant or breastfeeding should avoid taking CoQ10, according to the National Institutes of Health.
