Primary Outcome Measures:
  • Osteoprotegin level [ Time Frame: one year ] [ Designated as safety issue: No ]
    To assess the effect of vitamin D supplementation on osteoprotegin level in CKD patients


Secondary Outcome Measures:
  • Bone mineral density [ Time Frame: one year ] [ Designated as safety issue: No ]
    To assess the effect of vitamin D supplementation on bone mineral density in patients with CKD stage 1 and 2

  • vascular calcification score [ Time Frame: one year ] [ Designated as safety issue: No ]
    To assess the effect of vitamin D supplementation on vascular calcification score through performing lateral abdominal radiography or CT-based techniques in patients with CKD stage 1 and 2
