White Plains, New York, November 6, 2012 — Clinical studies suggest green coffee bean extract (GCBE) supplements can aid weight loss, but recent tests by indicate that many popular brands dont contain the amounts of extract listed on their labels. Among eight GCBE supplements selected for testing, half failed to pass ConsumerLab.coms review. One supplement did not contain any detectable GCBE, while three others contained no more than 14%, 64%, and 82% of the expected amounts. The amounts of extract were determined by chemically analyzing the products for their levels of chlorogenic acids — compounds found in GCBE and associated with its weight loss effect. The findings were confirmed in a second independent laboratory.

Small studies, including one conducted by The Dr. Oz Show, have shown that people taking supplements with GCBE lose about three pounds per month without a required change in diet or activity. Those given placebo lose about one pound per month. The daily dosage found to be effective has ranged from approximately 200 mg to 1,200 mg of extract, 45% to 50% of which is chlorogenic acids.

"Although a GCBE supplement may be helpful, you cant trust every brand," said Tod Cooperman, M.D., President of "We often see a large percentage of products fail our tests when there is new demand for a supplement and a rush by companies to meet that demand — as with green coffee bean extract." Dr. Cooperman added that reducing calories in the diet and increasing exercise remain the best approach to weight loss.

Four products passed's testing, as did an additional three products tested through's Voluntary Certification Program. Among the approved products, the cost to get a 400 mg dose of extract ranged by more than 300%, with the lowest cost being 20 cents.
