“…In Table 3, vitamin D levels>50ng/ml correlate with better glycemic control than patients with a vitamin D level of 30-50ng/ml (P-value<0.01). Different studies from various regions have investigated the effectiveness of vitamin D supplement therapy on glycemic control and level of HbA1c in type 1 diabetic patients and almost all of them indicated that vitamin D could improve glucometabolic status [41,42] and mean level of vitamin D was higher in the good glycemic group (70.96 ±22.66 ng/ml) than in the poor glycemic group (54.81±19.98ng/ml) [43]. A therapeutic dose of 50000IU/week can be given safely for 4) or other side effects as tolerable upper limit of daily dose of vitamin D in children up to 10000 IU/day [44].…”
