Our bodies produce CoQ10, a substance that's necessary for cells to function. It helps produce an important molecule known as adenosine triphosphate, or ATP. ATP is the fuel that helps power the energy-producing center of the cell known as mitochondria [source: University of Maryland Medical Center]. As we get older, our body produces less CoQ10, and as a result, our cells don't function as they should. In fact, those who suffer from chronic diseases such as Parkinson's, cancer, diabetes and cardiovascular disease have lower CoQ10 levels than healthy people [source: Mayo Clinic].
Researchers believe that taking CoQ10 as a supplement can help prevent heart disease. It helps prevent blood from clotting, and may act as an antioxidant, which protects our cells against the effects of free radicals that can damage cells and cause heart disease. Moreover, researchers suspect CoQ10 supplements may improve the health of diabetics by managing blood sugar, cholesterol and blood pressure [source: University of Maryland Medical Center].
Consumers can buy CoQ10 as a supplement in several forms, including soft gel capsules. There is even an oral rinse that helps treat gum disease. The supplement also comes in hard-shell capsules and tablets. Our bodies tend to absorb soft gel capsules better than hard capsules. Cosmetic companies also add CoQ10 to various products. The recommended dosage for adults is 30 to 300 mg. daily [source: University of Maryland Medical Center].
CoQ10 supplements seem to have no side effects except for an occasional upset stomach. However, consult with your physician if you want to take the supplement and are on any other medications [source: University of Maryland Medical Center].
