Vitamin D Deficiency Clinical Trial
Official title:
The Effects of Vitamin D3 Supplementation Alone and in a Combination With Omega-3 on the Association of C-peptide With Glycemic Control; A Randomized Controlled Trial in People With Vitamin D Deficiency
The Effects of Vitamin D3 alone and in a combination with omega-3 on the association of C-peptide with glycemic control
The data bout the effects of Vitamin D3 (VD3) alone and as a combination with omega-3 fatty
acids (Omega-3FA) on the association between C-peptide (CP) and the glycated hemoglobin
(HbA1c) is scarce, conflicting and nothing published in the literature review on the combined
effect of VD3 and Omega-3FA as a combination on the association of CP with glycemic control.
This study will be conducted to investigate the effects of (VD3) alone and as a combination
with Omega-3FA on the association between CP as an insulin secretion marker, and glycemic
control parameters represented by glycated Hemoglobin (HbA1c), on people with vitamin D
deficiency (VDD).
This randomized, placebo-controlled trial is designed to test the effects of (50,000 IU VD3/
weekly) and (300mg omega-3FA/daily) separately and as a combination for eight weeks, on the
serum levels of CP, 25-hydroxy vitamin D (25OHD) and HbA1c. this study will be carried out
during winter on 120 healthy Jordanian males and females with VDD with age range (25-50)
years. Fasting serum levels for 25OHD, CP, HbA1c, PTH, Calcium, Phosphate, ALT (Alanine
aminotransferase) and Urea were assessed at baseline and at the end of the trial.
