Beta thalassemia is a genetic disorder inherited by autosomal recessive inheritance, is present all over the world . Lifelong transfusions are necessary for people with beta-thalassemia, which can result in an iron buildup in the skin, liver, and kidneys that reduces the production of vitamin D. This study aims to evaluate vitamin D levels, blood groups, and demographic characteristics in beta-thalassemia patients. The current study was conducted at the thalassemia center and hereditary blood disease in Thi-Qar Province with eighty-eight blood samples collected from individuals. It was divided into three groups according to age range, the first group (2-6), the second group (7- 11), and the third group (12- 15). In the current study, there was a significant decrease in Vit-D3 levels among thalassemia patients compared to the control group (p ≤ 0.05) . As for age between the patients group and the control group, the highest proportion of patients in the third age group. As for gender, the results of the study found a non-significant difference at the (P ≤ 0.05 ) level between the patients group and the control group.
