Westchester, NY — November 15, 2005 — In a series of reports released today, ConsumerLab.com revealed test results for supplements used for weight loss, slimming, and blood sugar control. Among the twenty-three products that ConsumerLab.com selected and tested, only thirteen products passed the testing without problem or warning. Six products were contaminated with potentially harmful metals or had significantly more or less ingredient than expected. Several products also had very high amounts of caffeine. In fact, the daily dose of one product had as much caffeine as 30 cans of cola. Two products contained a mixture of caffeine and synephrine (from bitter orange) that could potentially cause adverse cardiovascular effects. In 2004, nearly $1.7 billion worth of weight loss supplements were sold in the U.S. according to Nutrition Business Journal.
The testing included popular products such EZ-Trim, Lean System7, PatentLean, Ripped Fuel, Thermosculpt, TRIMSPA, Xenadrine, and Zantrex-3, as well as products by Allmax, AST, Bodyonics, BodyTech, Life Extension, MegaFood, Metagenics, Natrol, Natural Max, Nature's Sunshine, New Chapter, PhytoPharmica, Rainbow Light, Solaray and Ultimate Nutrition.
Tod Cooperman, M.D., President of ConsumerLab.com, said, "Some supplements may provide modest benefit in weight loss and slimming, but people need to be wary of minefield of problems identified by these tests." Key findings are summarized below (by ingredient):
ConsumerLab.com screened all stimulant-based products (including those with bitter orange) for potential adulteration with non-listed stimulants such as amphetamine, ephedrine, fenfluramine, methamphetamine, phentermine, and phenylpropanlamine. None of these were detected.
In addition to the products selected by ConsumerLab.com, five products (including one made from green tea) are included in the reports for passing the same testing through ConsumerLab.com's Voluntary Certification Program. These products are from Nutrilite (Nutrilite® Chrompic Extra and Nutrilite® CLA 500), Nature's Bounty (Nature's Bounty® Green Tea Extract), Puritan's Pride (Puritan's Pride® Green Tea Extract) and Vitamin World (Vitamin World® CLA 1000 mg). A CLA raw material (CLAOne® from PharmaNutrients) also passed testing through ConsumerLab.com's Raw Material Testing Program.
ConsumerLab.com's Dr. Cooperman offered the following advice to people who consider using a weight loss supplement:
