Coq10 (Ubiquinone (Coenzyme Q-10))

Coq10 (Ubiquinone (Coenzyme Q-10))

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

Ubiquinone is likely effective in alternative medicine as an aid in treating coenzyme Q-10 deficiency, or reducing the symptoms of mitochondrial disorders (conditions that affect energy-production in the cells of the body).

Ubiquinone is also possibly effective in preventing migraine headaches, lowering blood pressure, reducing tissue damage after surgery, or preventing a second heart attack. Ubiquinone is also possibly effective in improving symptoms in people with congestive heart failure, nerve problems caused by diabetes, multiple sclerosis, fibromyalgia, muscular dystrophy, or a physical deformity of the penis (such as Peyronie's disease).

Ubiquinone has also been used to treat Alzheimer's disease, diabetes, amyotrophic lateral sclerosis (Lou Gehrig's disease), tiredness caused by taking cancer drugs, symptoms of Parkinson's disease, or muscle symptoms affecting Polio survivors. However, research has shown that ubiquinone may not be effective in treating these conditions.

Research also has shown that ubiquinone is not likely to be effective in increasing athletic performance or slow the progression of Huntington's Disease.

Other uses not proven with research have included treating asthma, COPD, cancer, diabetes, certain heart problems, hepatitis C, kidney problems, muscle problems caused by taking 'statin' cholesterol medicine, and other conditions.

It is not certain whether ubiquinone is effective in treating any medical condition. Medicinal use of this product has not been approved by the FDA. Ubiquinone should not be used in place of medication prescribed for you by your doctor.

Ubiquinone is often sold as an herbal supplement. There are no regulated manufacturing standards in place for many herbal compounds and some marketed supplements have been found to be contaminated with toxic metals or other drugs. Herbal/health supplements should be purchased from a reliable source to minimize the risk of contamination.

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