Many people take coenzyme Q10 supplements with the goal of improving their general state of health. According to the American Cancer Society, coenzyme Q10 was first identified in 1957, and since its discovery, researchers have examined the benefits of coenzyme Q10 in a number of different health conditions. The elderly and individuals with certain health conditions may be at risk for low coenzyme Q10 levels.
What Coenzyme Q10 Does Inside the Body
Coenzyme Q10 is part of an enzyme complex that is involved in many biochemical processes within the body including energy production, synthesis of proteins, and muscular contractions. In addition, coenzyme Q10 may also serve as an antioxidant that scavenges free radicals, which are harmful to tissues and cells. Although coenzyme Q10 has been studied in the treatment and prevention of heart disease and certain types of cancer, it remains unclear whether coenzyme Q10 supplements provides significant clinical benefits.
Coenzyme Q10 Supplements
Although the recommended daily dose of coenzyme Q10 is between 30 to 200mg, coenzyme Q10 supplements can provide between 50 to 1,200 mg per day, with the total daily dose divided into multiple dosing times. Although supplements can provide a larger than recommended dose of coenzyme Q10, reported adverse effects are rare. Coenzyme Q10 supplements are widely available at most pharmacies and retail outlets.
Coenzyme Q10 Supplements
Although rare, adverse side effects including allergic reactions, heartburn, headache, fatigue, diarrhea, and trouble sleeping have been reported. In addition, coenzyme Q10 may interfere with certain prescription medications. Insufficient safety data exists for special populations including pregnant and nursing mothers. Patients should speak with a physician before using coenzyme Q10 supplements.
Dietary Sources of Coenzyme Q10
In addition to the amount produced inside the human body, additional coenzyme Q10 can be obtained from dietary sources including beef, soybeans, peanuts, and fatty fish. Since coenzyme Q10 is fat-soluble, taking supplements with meals that can contain fat may aid with absorption inside the digestive tract. Coenzyme Q10 supplements are relatively safe and may benefit individuals with poor nutritional intake.
