About this study

It was designed to be applied to individuals with low vitamin D levels working in Fatih Sultan Mehmet Training and Research Hospital who meet the research conditions.

n the first phase of the study, demographic information will be recorded by asking demographic information from the people who volunteered to participate in the study and who meet the study criteria by using a questionnaire form and 3-day food consumption record information by face-to-face interview technique; anthropometric measurements of the participants will be taken and baseline blood values will be recorded. At the beginning of the experimental study, individuals will be randomized by computer-assisted randomization into four different groups. Biochemical analyses will be analyzed every two weeks, analyses will be repeated 1 month after the study and the effects of vitamin D enrichment on biochemical parameters will be determined.

Vitamin D status

Other

Four different groups will be compared with each other in terms of vitamin D effect.

Primary outcomes

  1. Vitamin D values

    Time frame: Pre-intervention, through study completion, an average of every two weeks and 1 month after the completion of the intervention

    During study, Vitamin D values are evaluated.

  2. Biochemical parameters

    Time frame: Pre-intervention, through study completion, an average of every two weeks and 1 month after the completion of the intervention

    Ca and parathormone are evaluated during the study.

  3. Demographic parameters

    Time frame: Pre-intervention

    Demographic values (age, gender, etc.) are also investigated.

  4. Food consumption record

    Time frame: Pre-intervention, through study completion, an average of every two weeks and 1 month after the completion of the intervention

    Before starting the study and after the end of study the food consumption of participants are evaluated.
