CoQ10 is a naturally occurring nutrient found in each cell of the body. This nutrient was first identified by University of Wisconsin researchers in 1957. It is found in foods, particularly in fish and meats. In addition to playing a significant role in the energy system of each of our cells, CoQ10 is also believed to have antioxidant properties and may play a role in heart health. Many who take this supplement notice that this nutrient enhances physical energy. For long term use I suggest no more than 30 mg or 50 mg a few days a week in those who are taking it for general health purposes.
Benefit and medical uses Studies with CoQ10 have mostly focused on its benefit involving certain types of cardiovascular diseases, including congestive heart failure and hypertension. However, this nutrient has also been evaluated for high cholesterol and in diabetes. Patients with high cholesterol levels who are placed on statin drugs such as Lipitor and Zocor should take additional CoQ10 in the amount of 10 to 50 mg daily, or a few times a week, to counteract the muscle damage from statin drugs (consult with your doctor). Studies in relation to Parkinson's disease treatment have not yielded consistent results. We still have a long way to go to determine the proper clinical role and benefit of this nutrient.
