Efficacy of the Dose Regimen of Oral Vitamin D 50,000 IU in the Treatment of Vitamin D Deficiency
Abstract:

 The main objective of the proposed study is to examine the Safety and Efficacy Evaluation of
 the Dose Regimen of Vitamin D 50,000 IU (Biodal) tablet supplementation in the treatment of
 population with vitamin D deficiency.

 A randomized, double-blind placebo, Parallel design comparing vitamin D with Placebo will be
 conducted on 60 Healthy males and females with vitamin D deficiency, age from 18 to 49 years
 who attend the rehabilitation clinics at Jordan University Hospital .Participants who met the
 inclusion criteria will be asked to sign an informed witnessed consent form. Results obtained
 are expected to assess the safety and efficacy of the dose regimen used in this study as per
 Biodal SmPC. This study will also contribute to the global body of knowledge in this field.
 The major findings generated from this study could open certain avenues for further research
 through the association of the status of vitamin D in serum .
The study design will be a prospective randomized double blind parallel design comparing
 Vitamin D with Placebo. This study will be conducted in Jordan University Hospital (JUH). The
 participants will be Healthy males and females with vitamin D deficiency (18 to 49 years
 old). All eligible males and females who agree to participate in the study will sign an
 informed witnessed consent form at the beginning of the study. The expected duration of
 participants participation will be around 120 days and the number of visits for each

 the third on day 30, the fourth on day 60, the fifth on day 90 and the sixth or the last
