However, the failure to identify the responsible biomolecules(s) that bind chromium(III) and their mode of action, particularly a postulated species named glucose tolerance factor or GTF, resulted in the status of chromium being questioned in recent years, such that the question of its being ...
Typical doses for weight loss and lean mass gains have used 200-400 mcg per day. Additional studies are underway to determine the degree to which chromium may be helpful as a weight loss and anabolic aid.2,16,17,18Presumably chromium is effective in these applications due to its ability to...
The GTF like structure of chromium picolinate determines its good absorption rate and can more effectively exert its biological functions. According to reports, the absorption rate of ordinary chromium preparations is around 0.5%, while the absorption rate of chromium picolinate r...

The GTF-like structure of chromium picolinate determines its own better absorption rate and can play its biological function more effectively. It is reported that the absorption rate of common chromium preparation is about 0.5%, while the absorption rate of chromium picolinate is 2%-5%(Anderson,...
Uptake of various forms of chromium, including GTF chromium is in a low 1 - 3% range, with the absorption ofChelated Chromiumbeing usually closer to 25%, so chelated chromium is the preferable choice for specific medical applications. For instance, when chromium is used for inflammatory condition...
In 1977, Toepfer thought that GTF is the biologically active form of chromium with its structure being the complex formed between nicotinic acid chromium and aspartic acid, glutamic acid, glycine and cysteine. The GTF-like structure of chromium picolinate class determines its own excellent absorption...
Therefore, it is possible to perform the trans-membrane absorption on the intact structure with the molecular structure being similar to the GTF part. In 1977, Toepfer thought that GTF is the biologically active form of chromium with its structure being the complex formed between nicotinic acid ...
In addition, there is increasing evidence for the suggestion that the existence of the link between chromium and the glucose tolerance factor (Cr-GTF) is doubtful and that earlier findings indicating the existence of the Cr-GTF complex have been heavily influenced by contamination. The concentration...
Factors predisposing to such a deficiency vary with the circumstances: 1 ) a poor placental supply of GTF to the low birth weight neonate; 2 ) geographical variations in dietary chromium appear to be responsible for chromium deficiency in association with protein-calorie malnutrition in some, but ...
