Brief Summary
The main objective of the study is to assess changes in the concentration of vitamin D metabolite in serum throughout the academic year and to examine its relationship with the occurrence of inflammation indicators, dietary habits, nutritional status, severity of depressive states, and cognitive abilities in a group of students. An additional objective will be to assess the relationship between the genotype in the CYP2R1 gene and the concentration of 25(OH) vitamin D.
