Vitamin D Supplementation for Pregnancy Complications; Systematic Literature Review

Introduction: Vitamin D deficiency is a global health concern, particularly among pregnant women, with prevalence rates reaching up to 40%. This deficiency poses risks to both maternal and fetal health, leading to complications such as gestational diabetes, preeclampsia, and preterm labor. Content: This study employed a literature review approach, collecting data from Google Scholar, ScienceDirect, and Technology Index (SINTA). Articles were selected based on inclusion criteria: international journals published between 2017 and 2024, focusing on the effectiveness of vitamin D during pregnancy. Exclusion criteria included journals ranked >Q3 (SJR) and >3 (SINTA). The review process involved critical appraisal, skimming, scanning, and thematic analysis. Conclusion: Findings indicate that vitamin D supplementation reduces pregnancy complications. Future research should explore the extent of its effectiveness in optimizing maternal and fetal health outcomes.
