多年来的研究表明，葡萄糖耐量因子（GTF）减少或缺乏导致的胰岛素活性降低是Ⅱ型糖尿病（NIDDM）的发病机制之一。GTF是由3价铬、菸草酸和多种氨基酸组成的低分子量阳离子复合物，其中3价铬是GTF的中心活性成分。GTF经铁转运至血液后，与胰岛素直接结合成复合物。已证实，NIDD Over the years, studies have shown that reduced insulin activity due to reduced or lack of glucose tolerance factor (GTF) is one of the pathogenesis of type 2 diabetes mellitus (NIDDM). GTF is a low molecular weight cationic complex composed of trivalent chromium, tobacco acid and a variety of amino acids, of which trivalent chromium is the central active ingredient of GTF. GTF is transported to the blood by iron and binds directly to insulin as a complex. Has been confirmed, NIDD
