The aim of this study is assessment of effects of zinc supplementation on glycemic control in patients with type 1 diabetesSubjects and Methods: Body mass index (BMI), serum levels of zinc and HbA1c of 29 patients with type 1 diabetes at baseline were measured. Then patients received 50 mg/day elemental zinc for 3 months. At the end of the treatment period serum levels of zinc and HbA1c were investigated again.Results: After treatment, mean serum zinc level did not differ significantly with before levels. But the mean HbA1c levels from 8.5±.7 reached to 8.1 ± .7 after treatment with zinc supplementation (P 25. As The higher the BMI, the percentage of reduction in HbA1c level was lower.Conclusion: The results of this study suggest that administration of zinc can reduce the levels of HbA1c in patients with type 1 diabetes.
