Many people take coenzyme Q10 supplements with the goal of improving general health. According to the American Cancer Society, coenzyme Q10 was first identified in 1957. Since its discovery, researchers have examined the benefits of coenzyme Q10 in a number of different health conditions. Coenzyme Q10 is widely available for purchase as an over-the-counter supplement.
Description
Coenzyme Q10 is part of an enzyme complex that is involved in many biochemical processes within the body, including energy production, muscle contraction and the synthesis of proteins. Coenzyme Q10 also may also as an antioxidant that scavenges free radicals that can cause damage to cells and tissues. Even though the body produces coenzyme Q10, older people and those with chronic diseases, including heart conditions, muscular dystrophy, Parkinson's disease, cancer, diabetes and HIV/AIDS, can have decreased levels, according to the Mayo Clinic. Although scientists have not firmly established the clinical benefits of coenzyme Q10, they have studied it to treat and prevent heart disease and certain cancers.
Dietary Sources
Coenzyme Q10 is available in fatty fish, beef, soybeans, and peanuts. Since coenzyme Q10 is fat-soluble, taking supplements with meals that can contain fat may aid with absorption into the body from the digestive tract. Since coenzyme Q10 supplements are relatively safe, they may be beneficial for individuals with poor intake of dietary sources.
Coenzyme Q10 Dose
The recommended daily dose of coenzyme Q10 is between 30 mg and 200 mg, according to the University of Maryland Medical Center. Some supplements contain more than that amount.
Safety
Coenzyme Q10 supplements are relatively safe, with only rare reports of adverse side effects. Those include allergic reactions, heartburn, diarrhea, fatigue, headache, and trouble sleeping. However, scientists have insufficient safety data for using coenzyme Q10 supplements in special populations, including children and pregnant women. Coenzyme Q10 may interfere with certain prescription medications. Patients should speak with a doctor before using coenzyme Q10 supplements.
