Supplements containing turmeric and its key compound, curcumin, may be helpful in treating inflammatory diseases and other conditions such as diabetes. However, recent tests by ConsumerLab.com found significant problems with two out of nine turmeric and curcumin products selected for testing.
Two supplements contained only 33.1% and 52.9% of their expected curcumin compounds (known as curcuminoids). In fact, one contained less than 10 mg of these compounds, while the typical dosage shown to work in studies is hundreds of milligrams! The other product was found to be contaminated with small amounts of the toxic heavy metals lead and cadmium. A third product failed to provide label information required by the FDA.
To help you get the best value from a turmeric or curcumin supplement, ConsumerLab.com calculated the cost to obtain a 500 mg dose of curcuminoids from each product. Among the top-quality supplements we identified, we found that you can get this dose for as little as 21 cents -- much less than you might expect.
Five popular, ground turmeric spice products were also tested. Several contained large numbers of insect parts,
which suggests insanitary storage, and one "organic" product contained a whole insect larva!
We did find one spice, however, which was exceptionally clean and not contaminated with Salmonella
, lead ,or cadmium.
