(HealthNewsDigest.com) - White Plains, New York, March 5, 2013 - A new report from ConsumerLab.com highlights the difficulty consumers have in selecting a supplement containing the anti-oxidant CoQ10 or its activated form, ubiquinol. ConsumerLab.com's recent tests found that one widely-sold supplement provides only 3.8% of its listed amount of CoQ10. Even among products found to contain their listed ingredients, consumers should choose carefully: ConsumerLab.com found the cost of a 100 mg dose of CoQ10 to range from 9 cents to several dollars. Some products include additional ingredients, such as those which may improve absorption of CoQ10 and ubiquinol, but may not necessarily justify a higher cost.

CoQ10 was the fourth most popular supplement (behind fish oil, multivitamins, and vitamin D) in a recent ConsumerLab.com survey of over 10,000 supplement users. Fifty-four percent of respondents used CoQ10, which was particularly popular with men and people over age fifty-five. U.S. sales of CoQ10 were $519 million in 2011, according to Nutrition Business Journal, an 8.2% increase over the prior year.

CoQ10 may help treat congestive heart failure and mitochondrial encephalomyopathies. There is some evidence, although mixed, that it may also help prevent migraine headaches, delay the progression of Parkinson's disease, and reverse side effects associated with cholesterol-lowering statin drugs. Research also suggests potential use in muscular dystrophy, AIDS, hypertension, and other conditions. A study of ubiquinol in elderly people suggested an improvement in self-assessed "vitality."

The new report is available at www.consumerlab.com/reviews/CoQ10_Ubiqunol_Supplements/CoQ10/ and covers 49 products. ConsumerLab.com selected 24 of these products and 24 others are included for passing the same tests in CL's Voluntary Certification Program.  Also included is a product similar to one which passed testing but sold under a different brand name.
