This cross-sectional observational study aims to assess serum concentrations of vitamin B12, folic acid, and vitamin D in women of reproductive age in Herzegovina. The study is led by Professor Vajdana Tomić, MD, PhD, who serves as the Principal Investigator, at the Faculty of Health Studies, University of Mostar, Bosnia and Herzegovina. The goal is to determine whether current international supplementation guidelines reflect the actual micronutrient status of this population. A total of 360 women aged 18-49 will be enrolled between December 2024 and December 2025 after providing informed consent. The findings will inform population-specific recommendations for micronutrient supplementation during the preconception period and pregnancy. The study will be conducted at the Faculty of Health Studies, University of Mostar, Bosnia and Herzegovina.
