High blood glucose (sugar) levels are a common problem for people with diabetes. This Iranian study aimed to evaluate changes in glucose levels following vitamin D3 supplementation in children with type 1 diabetes mellitus and vitamin D deficiency. Before the study, after three months, and at the end of the study, vitamin D levels and long-term glucose levels (HbA1C) were measured. Patients with vitamin D deficiency were treated with 300,000 IU (7500 µg) of vitamin D3. Additionally, a calcium supplement (40 mg/kg/day) was administered for 3 months. Differences were evaluated before and after the study. The results showed a significant decline in long-term glucose levels and a significant increase in vitamin D levels in these participants, which means that vitamin D3 supplementation improves important measured parameters in children with type 1 diabetes mellitus and vitamin D deficiency. More details can be found in the study.
