More than one in five weight loss, slimming and/or diabetes supplements fails evaluation.

White Plains, NY – April 3, 2002 – announced today that more than one in five products failed its recent Product Review of Weight Loss, Slimming and Diabetes-Management Supplements. The review looked at evidence for and against the use of popular ingredients used for these purposes and included laboratory testing of eighteen dietary supplements containing chromium (used to aid sugar metabolism in diabetes and weight loss), CLA (conjugated linoleic acid -- used to increase lean body mass), and/or pyruvate (used to increase fat metabolism).

The reasons that four of eighteen products did not pass’s evaluation were:

  • One product contained only 5% of the labeled amount of chromium. Such a reduction in chromium should be of concern to anyone relying on the product for its potential effect on insulin and blood sugar levels.
  • Another chromium product was found to contain a very small amount of a toxic form of chromium – chromium (VI). Chromium (VI) or “hexavalent” chromium is an industrial by-product and potential carcinogen (brought to national attention in the movie Erin Brokavich). The amount found in the product would not be expected to be harmful but is not desirable. Chromium (VI) was not detected in the other chromium products passing the review.
  • A product whose name included the words “Pyruvate 1000” and claimed “1000 mg of pyruvate complex” was considered potentially misleading as it was found to have only 240 mg of pyruvate.
  • Another product contained only 85% of its claimed amount of pyruvate.

“This review is a microcosm of the problems has found with other supplements, said Tod Cooperman, M.D., President of “Two products had less than what they claimed. Another was contaminated. And a third, due to vague language, could easily lead a consumer to expect four times the amount of active ingredient actually in the product. If a consumer is going to try a supplement, they should be able to get what they expect – nothing less and nothing more.”
