Abstract:
Chelation therapy and supplemental Cr have both been shown to lead to improved blood glucose, lipids, and insulin activity. Chelation therapy leads to the removal of toxic as well as essential metals. To determine if chelation therapy leads to increased urinary Cr losses and altered Cr homeostasis, 2 groups of subjects (1 group that had undergone only 1 or no chelation therapy and 1 group in which all subjects had undergone at least 19 chelation sessions) were evaluated for differences in possible Cr homeostasis based on urinary Cr losses. There were no significant differences in urinary Cr losses between the two groups of subjects and there were no significant increases in urinary Cr losses resulting from chelation therapy. Increases in urinary Cr losses were strongly influenced by supplementation but not chelation therapy.

EDTA: Direct, Back-, and Displacement Titration
Direct titration involves buffering the metal ion solution to the desired pH and directly titrating with standard EDTA until the endpoint. The optimum pH ensures a large conditional formation constant of metal−EDTA and visibility of the free indicator color in the solution. In addition, auxiliary complexing reagents are used to prevent the precipitation of metal hydroxides and...
Effects of EDTA on End-Point Detection Methods
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a result, EDTA...
Masking and Demasking Agents
