What is ubiquinone?

Ubiquinone is a vitamin-like substance that the body makes naturally. It is also known as Co Q-10, Coenzima, Ubidcarenone, Ubidécarénone, and Ubiquinol.

Ubiquinone is likely helpful in alternative medicine for treating coenzyme Q-10 deficiency and reducing symptoms of mitochondrial disorders (conditions that impact energy production in the body's cells).

Ubiquinone may also help prevent migraine headaches, lower blood pressure, reduce tissue damage after surgery, or prevent a second heart attack. It may also improve symptoms in people with congestive heart failure, nerve issues caused by diabetes, multiple sclerosis, fibromyalgia, muscular dystrophy, or Peyronie's disease.

Ubiquinone has been used to treat Alzheimer's disease, diabetes, amyotrophic lateral sclerosis (Lou Gehrig's disease), fatigue from cancer treatments, symptoms of Parkinson's disease, or muscle issues in Polio survivors. However, studies indicate that ubiquinone may not work for these conditions.

Research has also shown that ubiquinone is not likely to improve athletic performance or slow the progression of Huntington's disease.

Other uses that have not been proven include treating asthma, COPD, cancer, diabetes, certain heart issues, hepatitis C, kidney problems, muscle issues from 'statin' cholesterol medications, and other conditions.

It is unclear if ubiquinone is effective for any medical condition. The FDA has not approved this product for medicinal use. Ubiquinone should not replace medications that your doctor has prescribed.

Ubiquinone is often sold as an herbal supplement. Many herbal products lack regulated manufacturing standards, and some supplements have been found to contain toxic metals or other drugs. It is important to buy herbal/health supplements from a trustworthy source to reduce the risk of contamination.

Ubiquinone may also be used for purposes not listed in this product guide.

How should I take ubiquinone?

When thinking about using herbal supplements, talk to your doctor. You may also want to consult someone who is trained in herbal or health supplements.

If you decide to use ubiquinone, follow the instructions on the package or as directed by your doctor, pharmacist, or other healthcare provider. Do not take more of this product than what is recommended on the label.

The chewable ubiquinone should be chewed completely before swallowing.

To take the disintegrating tablet, use dry hands to take it out of the package and place it in your mouth. It will start to dissolve immediately. Do not swallow the tablet whole. Let it dissolve in your mouth without chewing.

Your blood pressure may need to be checked while you are using ubiquinone.

If you are going to have surgery, dental work, or a medical procedure, stop using ubiquinone at least 2 weeks beforehand.
