les produits génériques sont moins chers que les suppléments brevetés mais beaucoup contiennent bien moins que ce qu'ils prétendent
Clinical studies suggest green coffee bean extract (GCBE) supplements can help with weight management, but recent tests by ConsumerLab.com indicated that many popular brands don't contain the amounts of extract listed on their labels. Among eight GCBE supplements selected for testing, half failed to pass ConsumerLab.com’s review. One supplement did not contain any detectable GCBE, while three others contained no more than 6%, 29%, 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 effect on weight. The findings were confirmed in a second independent laboratory.
