Effects of 6 months of chromium or combined chromium with vitamins C and E supplementation on blood glucose and insulin variables
| Placebo (n = 10) | Cr (n = 10) | Cr + C + E (n = 10) | |
|---|---|---|---|
| Fasting glucose (mmol/L) | |||
| Baseline | 12.25 ± 0.93 | 12.52 ± 0.51 | 12.24 ± 0.45 |
| 6 months | 12.23 ± 0.43 | 11.12 ± 0.42* | 11.04 ± 0.53* |
| HbA1c (%) | |||
| Baseline | 10.1 ± 0.4 | 10.2 ± 0.5 | 10.0 ± 0.5 |
| 6 months | 10.2 ± 0.4 | 9.5 ± 0.2* | 9.3 ± 0.5* |
| Insulin (pmol/L) | |||
| Baseline | 108.38 ± 16.50 | 103.58 ± 12.19 | 106.2 ± 11.11 |
| 6 months | 120.72 ± 7.12 | 98.74 ± 9.55* | 92.07 ± 8.67* |
| Insulin resistance index | |||
| Baseline | 8.3 ± 0.9 | 8.1 ± 0.9 | 8.1 ± 0.8 |
| 6 months | 9.2 ± 0.8 | 6.9 ± 0.7* | 6.3 ± 0.9* |
1. Values are the mean ± SD.
2. “*” means significant difference between the placebo group and the Cr or Cr + C + E group.
3. Insulin resistance index (HOMA-IR) = fasting blood glucose (mmol/L) × fasting serum insulin (µU/mL)/22.5
