Summary

This study will measure vitamin B12, folic acid, and vitamin D levels in 360 women aged 18-49 in Herzegovina. Participants give blood samples, and no treatment is given. The goal is to see if current supplement guidelines match actual vitamin levels, so better recommendations can be made for women before and during pregnancy.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this study could lead to better, population-specific vitamin supplement recommendations for women planning pregnancy.
What could go wrong
This is an observational study, not a treatment trial. It only measures current vitamin levels and cannot prove that changing supplements improves health outcomes.
