This study was carried out to investigate the effect of Zinc supplementation on the serum levels of TT4 and TT3 . Zinc concentration was determined by atomic absorption spectroscopy in sera of diabetic patients’ type (2) and healthy individuals. The results show a high significant deficiency of zinc concentration (P < 0.001) in diabetic patients when comparison with healthy group. In addition ,our study investigates the effect of zinc oral supplementation on thyroids hormones in diabetics (Type 2) by the use of two control groups ( A:Healthy control ) , and ( B : Diabetic control ) , and C-group treated with zinc supplements for 10 weeks period .The results shows that the elevation of TT4 and TT3 level in C group after the intake of zinc supplementation and this elevation was highly significant (P< 0.001) .
