What is CoQ10?
CoQ10 or coenzyme Q-10, is a vitamin-like substance found in virtually all cells of the human body. Ongoing studies are focusing on the specific functions of CoQ10, specifically its use as a powerful antioxidant in response to oxidative stress in the body, and its role in preventing disease progression.


How does it work?
CoQ10 is an electron carrier in the mitochondria, or energy-producing part of the cell. Therefore, CoQ10 is necessary for energy production in the body. Also, another important function of CoQ10 is that it is a powerful antioxidant. We know that antioxidants help protect our body cells from becoming damaged, so CoQ10 plays a part in this process. In particular, CoQ10 prevents low density lipoproteins, or LDL, (bad cholesterol) from becoming oxidized, which helps prevent it from becoming a damaging substance to the arteries.
CoQ10 also enhances the antioxidant activity of vitamin E and vitamin C, so taking these antioxidants together can provide the most benefit. CoQ10 may play a role in reducing risk of cardiovascular disease.


Is CoQ10 a powerful antioxidant?
Yes. CoQ-10 is not a vitamin, but it is considered a vitamin-like substance. Because of its role as an antioxidant, particularly against LDL cholesterol, supplementation is often recommended for those at risk for heart disease,or for those who currently have heart complications or elevated blood pressure.


Are there foods which contain CoQ10?
Yes. Oily fish such as salmon contains some CoQ-10, as well as spinach and whole grains.


Should I be taking CoQ10 if I am concerned about heart health?
Yes, I would recommend a CoQ10 supplement for those currently taking a statin drug to lower cholesterol. Statins, used to help lower blood cholesterol levels, are frequently prescribed for heart patients, but they actually deplete the body of CoQ10. For those not on statin medication, CoQ10 can also be beneficial, due to its heart-healthy properties. Usually, for therapeutic benefits, 100 mg or more of CoQ10 is recommended. For general health, a lower dose such as 30- 100 mg/day can be taken for antioxidant benefits
