Description

Coenzyme Q10 (CoQ10) is a substance that helps convert food into energy. CoQ10 is found in almost every cell in the body, and it is a powerful antioxidant. Scientists believe free radicals contribute to the aging process, as well as a number of health problems, including heart disease and cancer. Antioxidants, such as CoQ10, can neutralize free radicals and may reduce or even help prevent some of the damage they cause.

Use of CoQ10 may help prevent or treat certain conditions.  Taking CoQ10 within 3 days of a heart attack can help reduce subsequent heart attacks and chest pains.   People with congestive heart failure may have low levels of CoQ10 so taking supplements may help reduce swelling in the legs, make breathing easier and increase energy.

Studies have shown that taking CoQ10 for a 1-3 months may lower blood pressure and has positive effects on lowering cholesterol. Clinical research indicates that introducing CoQ10 prior to heart surgery, including bypass surgery and heart transplantation, can reduce damage caused by free radicals, strengthen heart function, and lower the incidence of irregular heart beat (arrhythmias) during the recovery phase.

Preliminary clinical studies also suggest that CoQ10 may:

• Improve immune function in people with HIV or AIDS
• Increase sperm motility, improving male fertility
• Be used as part of the treatment for Parkinson disease
• Improve exercise ability in people with angina
• Help prevent migraines

Primary dietary sources of CoQ10 include oily fish (such as salmon and tuna), organ meats (such as liver), and whole grains. Most people get enough CoQ10 through a balanced diet, but supplements may help people with particular health conditions.

Because of the potential for side effects and interactions with medications, you should take dietary supplements only under the supervision of a knowledgeable health care provider.
