A Remedy For
Like all heart medications, Coenzyme Q10 is not a cure. However, for some people suffering from congestive heart failure, irregular heartbeat, or angina, it may ease symptoms and improve cardiac function. Some doctors also recommend it after heart surgery to speed recovery with a minimum of permanent damage.
Some advocates contend that Coenzyme Q10 can stave off hardening of the arteries by discouraging the build-up of plaque on artery walls. Others suggest that it can boost the immune system, helping to prevent the spread of cancer. It has also been recommended for a host of additional disorders ranging from high blood pressure, diabetes, allergies, and fatigue to Alzheimer's disease, Bell's palsy, Huntington's disease, Ménière's disease, muscular dystrophy, and deterioration of the retina. However, its effectiveness for all such conditions has yet to be scientifically verified.
What It Is; Why It Works
Found in every cell in the body, Coenzyme Q10 plays a vital role in the production of energy, triggering the conversion of nutrients into a "fuel" for the cells to burn. This substance, called adenosine triphosphate (ATP), can't be stored in quantities sufficient to sustain optimum bodily functions for more than a few minutes. Stores must be continually renewed, making an ample supply of Coenzyme Q10 mandatory.
Adequate levels of the enzyme are particularly crucial for the heart because it's constantly in motion, burning twice as much energy as the other organs. If supplies of the enzyme decline, the action of the heart muscle will tend to weaken, reducing the amount of fresh blood the heart can pump out to the body. It is for this reason that some researchers regard a deficiency of the enzyme as an aggravating factor in conditions such as congestive heart failure.
Good dietary sources of Coenzyme Q10 include beef, pork, and lamb; certain types of fish and shellfish; vegetables such as broccoli and spinach; and vegetable oils. If you have a heart condition, however, you may want to consider a commercial supplement.
Avoid If...
No known medical conditions preclude the use of Coenzyme Q10.
Special Cautions
By itself, Coenzyme Q10 is not a sufficient treatment for any type of heart disease. It is generally employed as a supplement, rather than a replacement, for standard medical therapy. Do not attempt to substitute it for any of your regular prescriptions.
Possible Drug Interactions
No interactions have been reported.
Special Information If You Are Pregnant or Breastfeeding
Do not use Coenzyme Q10 while pregnant or breastfeeding.
How to Prepare
Coenzyme Q10 is available in capsule, tablet, softgel (gel cap), and chewable form. To improve its absorption, take it with some type of oil (olive oil is recommended) or fat (peanut butter, for example). It is also best to take your dosage with meals.
Store in a dry and cool place, away from light. Do not allow to freeze.
Typical Dosage
Dosage recommendations range from 30 milligrams to 400 milligrams daily, generally increasing with the severity of the problem. Large daily doses are typically divided into 2 or 3 smaller doses (for example, one 60 milligram tablet taken 2 times a day instead of a single 120 milligram tablet taken once).
If you are taking the enzyme for a heart condition, it may be 2 to 8 weeks before you notice any benefit, and you will need to continue taking the product to maintain any improvement.
Overdosage
Since Coenzyme Q10 is not toxic, experts say you may take large amounts without danger.
