What is ubiquinone?

Ubiquinone is a substance similar to a vitamin that the body makes naturally. Ubiquinone 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 or reducing symptoms of mitochondrial disorders (conditions that affect how energy is produced 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 problems from diabetes, multiple sclerosis, fibromyalgia, muscular dystrophy, or a physical deformity of the penis (such as Peyronie's disease).

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

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

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

It is uncertain whether ubiquinone is effective for any medical condition. The FDA has not approved medicinal use of this product. Ubiquinone should not replace medication prescribed by your doctor.

Ubiquinone is commonly sold as an herbal supplement. There are no regulated manufacturing standards for many herbal products, and some supplements have been found to contain toxic metals or other drugs. Herbal/health supplements should be bought from a trustworthy source to reduce the risk of contamination.

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

How should I take ubiquinone?

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

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

The chewable ubiquinone must be chewed completely before you swallow it.

Use the measuring device that comes with the liquid ubiquinone to measure it (do not use a kitchen spoon).

To take the disintegrating tablet, use dry hands to take it out of the package and put 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 need to have surgery, dental work, or any medical procedure, stop taking ubiquinone at least 2 weeks before.

Store at room temperature, away from moisture and heat.

Call your doctor if the condition you are treating with ubiquinone does not get better, or if it worsens while using this product.
