Randomization (investigator's opinion)
Randomized
Randomization description
In this study, a random block design will be used for randomization. In this way, 24 blocks of 4 will be made using codes A, B, C, and D that these blocks will be numbered from 1 to 24 (ACDB, BADC, BCAD, BCDA, ABCD, ABDC, ACBD, ACDB, ADBC, ADCB, BDAC, BDCA, CBAD, CBDA, CABD, CADB, CDBA, CDAB, DABC, DACB, DCAB, DCBA, DBAC, DBCA) and then using R software, twenty-six codes from blocks 1 to 24 are randomly selected.
Blinding (investigator's opinion)
Double blinded
Blinding description
Vitamin D supplement and placebo will be provided by Zahravi Pharmaceutical Company (Iran). Magnesium placebo will be made from starch with the same color and shape as the magnesium supplement by the Faculty of Pharmacy of Hormozgan University of Medical Sciences. In this study, blinding of participants, staff, and investigators will be done (Magnesium and Vitamin D supplements and placebos will be placed in the same package with codes of A, B, C, and D by a responsible person who is not aware of the study objectives. The codes will not be available to researchers until after statistical analysis. In order to blind the participants, they will be explained at the beginning of the study who will receive one of four types of intervention and will not be told the exact type of supplement.
