ConsumerLab.com's Current Test Results
20 May 2003

ConsumerLab.com conducts independent testing of popular and widely available brands of supplements against a high standard of quality. They examine clinical research findings for each specific supplement to learn "what works"—then compare test results of brands against this formulation.

Names of brands that pass these tests are posted on their website, www.ConsumerLab.com. Beginning with its review of saw palmetto on May 20, 2003, ConsumerLab will also post the names of brands that fail these tests. Pages available to the public contain a few examples of passing brands, but the full list is available only to subscribers. The subscription fee will soon rise to $24/year.

Producers of passing brands can purchase a license to print the ConsumerLab quality seal on the labels and literature of approved products. ConsumerLab informs manufacturers if its brand fails the testing. Brands that were not tested can pay a fee to have their products tested.
