Plasma amino acids in early pregnancy and fetal growth trajectories across pregnancy: findings from a multi-racial U.S. pregnancy cohort

Key Points

• Fetal growth trajectories depend significantly on plasma amino acids during early pregnancy and throughout gestation.
• Plasma amino acids showed a strong correlation with specific fetal growth metrics, influencing weight and development.
• Observational analysis of a diverse U.S. pregnancy cohort assessed plasma amino acids and fetal outcomes over time.
• Findings may highlight the crucial link between maternal nutritional status and fetal development, particularly among diverse populations.
