The core functional ingredient of Qimei's blood sugar regulating products is "Glucose Tolerance Factor-GTF", which is a complex of trivalent chromium and a variety of amino acids, which is Qimei's unique patented technology.  Although there are similar blood sugar regulating products on the market, the mechanism of action and product manufacturing method are far from that of Qimei products. Facts have proved that Qimei's unique core technology has not been surpassed or imitated for more than 20 years.
