SOME TURMERIC AND CURCUMIN SUPPLEMENTS FAIL QUALITY REVIEW

— ConsumerLab.com Finds 20% of Turmeric Supplements Selected for Review Deliver Less than 15% of Promised Compounds —

WHITE PLAINS, NEW YORK — FEBRUARY 16, 2011— Supplements containing the herb turmeric or its key compound, curcumin, have become popular in the U.S.  ConsumerLab.com cautioned today that two out of ten turmeric products recently selected for quality testing were found to provide only 7.7% and 14.7%, respectively, of expected curcuminoid compounds. Unlike some turmeric supplements tested in the past, however, none of the recently tested products exceeded strict limits for lead and cadmium contamination.

Turmeric has been shown to have anti-inflammatory and anti-oxidant activities. Recent research has focused on curcuminoids, the specific compounds in turmeric including curcumin which give turmeric its orange-yellow color. Studies suggest a role for curcuminoids in the treatment of a range of diseases including ulcerative colitis, rheumatoid arthritis, and chronic anterior uveitis (an autoimmune disease of the eye), as well as for indigestion. According to Nutrition Business Journal, sales of turmeric and curcumin supplements grew to $59 million in 2009, up from $43 million in 2008.

"Consumers need to select turmeric or curcumin supplements carefully to be sure they are getting a quality product. The products that failed our testing would deliver only a small fraction of the doses expected from their labels. In addition, because curcumin is poorly absorbed, certain specially formulated products may offer greater bioavailability," said Tod Cooperman, M.D., President of ConsumerLab.com. To help consumers get the best value from a supplement, ConsumerLab.com calculated the cost to obtain a 500 mg dose of curcuminoids, which ranged from 13 cents to 52 cents among products that passed testing, some of which included bioavailability enhancers. For the two products that failed testing, the costs were $3.44 and $7.88, due to the small amounts of curcuminoids that they actually contained.
