ConsumerLab.com, LLC ("CL") is the leading provider of independent test results, supplement certification seals, and related information to help consumers and healthcare professionals identify the best quality health and nutrition products. A majority of CL’s research is cited in books, by the media, and at professional conferences. Since its establishment in 1999, CL has tested over 7,000 products, representing more than 1,000 different brands and almost all types of popular supplements for children, adults, and pets.
ConsumerLab.com has undoubtedly the highest testing standards of any third-party group verifying the quality of dietary supplements. CL is also the only third-party certification group that freely publishes its testing methods and quality standards.
To be approved as ConsumerLab-certified supplements, products must be tested to measure whether they meet the level of quality and recognized standards of identity claimed on the label, contain the amounts of ingredients claimed on the label, are free of contaminants, and can break apart properly to be used by the body. Not only do these criteria have to be fully met for the ConsumerLab Approved Quality Seal, but the products must be tested every twelve months based on a random sample purchased on the open market. CL does not accept product samples from manufacturers and may select samples at any time during the year to avoid sampling bias.
