What is LiQ-10 (coenzyme Q-10)?

Ubiquinone is a substance similar to vitamin C that is produced naturally by the body. Ubiquinone can also be known as Co-Q-10, Ubidcarenone, Ubidecarenone, and Ubiquinol.Ubiquinone may be effective in alternative medicine to treat coenzyme-Q-10 deficiency or reduce the symptoms of mitochondrial diseases (conditions affecting energy production in the body's cells).Ubiquinone may also be effective at preventing migraine headaches. It can lower blood pressure, reduce tissue damage following surgery, or prevent a second attack. Ubiquinone may also be effective for improving symptoms of congestive cardiac failure, nerve damage caused by diabetes, or multiple sclerosis. It can also help with fibromyalgia and muscular dystrophy.Ubiquinone is also used to treat Alzheimer’s disease (Lou Gehrig’s disease), diabetes, fatigue caused by cancer drugs, Parkinson’s symptoms, and muscle symptoms in polio survivors. Research has shown, however, that ubiquinone is not effective for treating these conditions.The research also shows that ubiquinone does not appear to have any effect on increasing athletic performance or slowing the progression of Huntington's disease.Researchers have not yet proven that other uses, such as treating asthma, COPD (including certain heart conditions), cancer, diabetes, hepatitis C (including kidney problems), muscle problems from takingstatin cholesterol medicine', and others, are also effective.There is no way to know if ubiquinone can be used as a treatment for any medical condition. The FDA has not approved the use of this product for medical purposes. Ubiquinone is not to be substituted for medication prescribed by your doctor.Ubiquinone can be sold as an herbal supplement. Many herbal compounds are not manufactured to regulated standards, and some supplements on the market have been found to be contaminated with toxic drugs or metals. To minimise the risk, herbal or health supplements must be purchased from a reputable source.Ubiquinone can be used in other ways not mentioned in the product guide.
