What this Trial Is About
This study aims to understand how much leucine, an essential amino acid, and protein building block, healthy pregnant women need during early and late pregnancy. Leucine plays an important role in supporting muscle health and fetal growth. Participants will consume carefully prepared meals and provide breath, urine samples, and one blood sample so researchers can measure how the body uses leucine at different stages of pregnancy. The results will help improve nutrition guidelines for pregnant women to better support maternal health and healthy fetal development.
