Coenzyme Q10, generally shortened to CoQ10, is a naturally produced enzyme that your body needs to function properly at a cellular level. Inside the body, CoQ10 is concentrated in the heart, liver, kidneys and pancreas. It is also present in dietary sources such as meats and seafood. Certain medications can decrease CoQ10 levels, notes Mayo Clinic. Supplementation is an option, though the research is mixed about whether or not such supplements are beneficial to all people.
Treating Diseases
The main use of CoQ10 is in treating heart problems, including congestive heart failure, angina and high blood pressure, which can be caused by genetic predisposition, lifestyle choices, medication or disease. CoQ10 has been used to moderate the heart health effects of diabetes, gum disease, certain forms of cancer, Huntington's disease, Parkinson's, Lyme disease and muscular dystrophy. MedlinePlus notes the most promising results are in lowering the risk of second heart attacks and reducing blood vessel-related problems following bypass surgery. CoQ10 has also shown promise in reducing the occurrence of migraine headaches.
Energy Level Effects
CoQ10 can potentially help increase energy and exercise tolerance due to its role in the production of adenosine triphosphate (ATP), a nucleotide in the body's cells that powers energy reactions. Taking CoQ10 supplements may thus be helpful for some but not all people with energy level problems, according to Mayo Clinic.
Life Expectancy
CoQ10 has gained some attention as a substance that can potentially increase life expectancy. Natural levels of the enzyme are highest in the first 20 years of life. As a result, Mayo Clinic notes that some researchers believe that by restoring CoQ10 levels to those found in youth, life span could potentially be increased. Bacteria tests are promising, but MedlinePlus reports that the results have not yet been replicated in animal studies.
Potential Dangers of CoQ10
The enzyme is considered safe in adults, but there are side effects to monitor. Allergic reactions are rare but severe, and patients taking medications for high blood pressure may actually cause themselves low blood pressure by combining CoQ10 supplements with their blood pressure medication. Cancer patients undergoing chemotherapy and pregnant women should also consult their doctors prior to taking CoQ10 supplements.
