Turmeric has been shown to have anti-inflammatory and anti-oxidant activities. Recent research has focused on turmeric's curcuminoid compounds, such as 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 30.6% in 2012 to $108 million.
Commenting on the findings, Tod Cooperman, M.D., President of ConsumerLab.com said, "Consumers need to select turmeric or curcumin supplements carefully to be sure they are getting a quality product. Some of the products that failed our testing delivered only a fraction of the dose expected from their labels and that dose may not be clinically useful. We also found a disgusting amount of filth from insects in some turmeric spices which, although not a safety concern, can largely be avoided," 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 21 cents to $1.64 among products that passed testing, some of which included bioavailability enhancers. ConsumerLab.com also identified one turmeric spice which was exceptionally clean and not contaminated with Salmonella, lead or cadmium.
