ConsumerLab.com Reports on CoQ10 Supplements

By Marian Zboraj | October 23, 2006

New test results from ConsumerLab.com, White Plains, NY, for CoQ10 supplements have shown that all of the products selected contained amounts of ingredient consistent with their labels. Tests in 2004 and 2000 had identified some products with significantly less CoQ10 than labeled. The suggested dosage among current products, however, was found to vary widely from as little as 15 mg to up to 400 mg per day. ConsumerLab.com advised consumers not to rely on products suggested serving sizes and to consult their healthcare providers to select a dose based on the condition for which the supplement is to be used.

The report provides results for 36 products, of which ConsumerLab.com selected 16. Twenty were tested at the request of their manufacturers/distributors through CL's Voluntary Certification Program and are included for having passed testing. Also identified are eight products similar to ones that passed but sold under a different brand name. Brands included in the report are Allergy Research, Berkley & Jensen, Bluebonnet, Carlson, Chew Q (Tishcon), Doctor's BEST, Gary Null's, GNC, Healthy Origins, Inno Vite, LiQ-10 (Tischcon), Longs, Nature's Bounty, PhytoPharmica, Pro Health, Puritan's Pride, Q-Gel (Gel-Tec/Tischcon), Rite Aid, Shaklee, Spring Valley, Sundown, Trace Minerals Research, USANA, Vitamin World, Vitanica and Vitasmart.

CoQ10 is among the most popular supplements in the U.S. with $284 million sold in 2004, according to figures from Nutrition Business Journal. It may help treat congestive heart failure, prevent migraine headaches and delay the progression of Parkinson's disease. It may also help reverse side effects associated with "statin" drugs to lower high cholesterol. And it may be useful in muscular dystrophy, AIDS, hypertension, mitochondrial encephalomyopathies and other conditions. Although sometimes touted for enhancing athletic performance, this effect has not been well demonstrated.
