Table 2.
Changes of serum 25(OH)D, calcium and intact parrathyroid hormone ater weekly administration of 20,000 U vitamin D2 for 12 weeks as compared to weekly 15,000 U vitamin D3 supplementation in prediabetic subjects.
| Variables | Vitamin D2 20,000 IU/week (n = 14) | Vitamin D3 15,000 IU/week (n = 15) | P value |
|---|---|---|---|
| Serum 25-hydroxyvitamin D (nmol/L) | 98.0 ± 13.0 | 97.0 ± 14.1 | 0.81 |
| Serum calcium (mmol/L) | 2.3 ± 0.03 | 2.2 ± 0.03 | 0.52 |
| Serum intact parathyroid hormone (pmol/L) | 5.0 ± 1.1 | 4.9 ± 1.5 | 0.65 |
Differences between two groups were assessed by Mann-Whitney U-test.
