Abstract: (10558 Views)
Background: The present study designed to assess the effect of Mg+Zn, vitamin C+E, and combination of these micronutrients on glycemic control and insulin resistance in type 2 diabetic patients
Methods: In a randomized, double-blind, placebo controlled clinical trial, 69 type 2 diabetic patients were randomly divided into four groups, each group receiving one of the following daily supplement for 3 months group M: 200 mg and 30 mg Zn (n=16), group V: 200 mg vitamin C and 150 mg vitamin E (n=18), group MV: minerals plus vitamins (n=17), group P: placebo (n=18).Fasting blood glucose, fructosamine, HbA1c and serum insulin were measured at the beginning and at the end of 3 months supplementation. Insulin resistance was calculated by HOMA score. Treatment effects were analyzed by general linear modeling.
Results: After 3 months of supplementation fasting blood glucose decreased in MV group (165±46 vs 177±41 mg/dl, p=0.035). There was no significant change in fructoseamin, HbA1c, serum insulin or insulin resistance in treatment groups.
Conclusion: The results of the present study provide evidence for the effects of combination of Mg, Zn and vitamin C and E supplementations on improvement of fasting blood glucose but not fructosamine, HbA1c, serum insulin or insulin resistance in type 2 diabetic patients.
