The Influences of Chromium Supplementation on Glycemic Control, Markers of Cardio-Metabolic Risk, and Oxidative Stress in Infertile Polycystic ovary Syndrome Women Candidate for In vitro Fertilization: a Randomized, Double-Blind, Placebo-Controlled Trial.

“Compared with the placebo, taking chromium supplements led to significant reductions in fasting plasma glucose (- 2.3 ± 5.7 vs. + 0.9 ± 3.1 mg/dL, P = 0.03), insulin levels (- 1.4 ± 2.1 vs. + 0.4 ± 1.7 μIU/mL, P = 0.004), homeostatic model of assessment for insulin resistance (- 0.3 ± 0.5 vs. + 0.1 ± 0.4, P = 0.005), and a significant increase in quantitative insulin sensitivity check index (+ 0.004 ± 0.008 vs. - 0.001 ± 0.008, P = 0.03).”

“In addition, chromium supplementation significantly decreased serum triglycerides (- 19.2 ± 33.8 vs. + 8.3 ± 21.7 mg/dL, P = 0.004), VLDL- (- 3.8 ± 6.8 vs. + 1.7 ± 4.3 mg/dL, P = 0.004) and total cholesterol concentrations (- 15.3 ± 26.2 vs. - 0.6 ± 15.9 mg/dL, P = 0.03) compared with the placebo.”
