Chromium and cysteine supplementation have been shown to improve glucose metabolism in animal studies. This study examined the hypothesis that chromium dinicocysteinate (CDNC), a complex of chromium and L-cysteine, is beneficial in lowering oxidative stress, vascular inflammation and glycemia in type 2 diabetic patients (T2D). Cell culture studies using monocytes and adipocytes models were performed to delineate the molecular mechanisms by which L-cystiene supplementation supplementation increases the glucose utilization. Diabetic patients enrolled in this study were given placebo for one month for stabilization and then randomized into one of three groups: placebo (P), chromium picolinate (CP) or CDNC, after which they received daily oral supplementation for 3 months. Of the 100 patients enrolled in the study, 74 patients completed it. There were 25 patients in P group, 25 in CP and 24 in CDNC supplemented group who completed the study. Blood markers of glycemia, vascular inflammation, HOMA insulin resistance and oxidative stress were determined at randomization and after 3 months of supplementation with P, CP or CDNC. There was a significant decrease at 3 months in insulin resistance (p=0.02) and in the levels of protein oxidation (p=0.02) and TNF-α (p=0.01) in the CDNC supplemented cohort compared to baseline. However, there was no statistically significant change in these markers in the CP supplemented group compared to baseline. Insulin levels significantly decreased (p=0.01) for subjects receiving CDNC but not CP. Cell culture studies using monocytes and adipocytes models demonstrate that L-cysteine supplementation supplementation increases the glucose utilization by up-regulating the insulin stimulated (PI3K/AKT) and insulin independent (SIRT1/AMPK/PPARγ) glucose metabolism pathways essential for maintenance of glucose homeostasis. CDNC supplementation lowers insulin resistance by reducing blood levels of TNF-α, insulin, and oxidative stress in type 2 diabetic patients. Therefore, CDNC supplementation has potential as an adjunct therapy for individuals with type 2 diabetes. (Supported by NIH RO1 DK072433 and Malcolm Feist Chair in Diabetes)
