(This age range represents typical reproductive age and minimizes potential confounding effects related to adolescent growth or age-associated metabolic changes.)\n* Singleton pregnancy. (Restricting participation to singleton pregnancies reduces variability in nutrient requirements and metabolic demands associated with multiple gestations.)\n* Gestational age of either 11-20 weeks (early gestation) or 31-40 weeks (late gestation).\n\n(These time points represent physiologically distinct stages of pregnancy, allowing comparison of leucine requirements across early and late gestation.)\n\n* Participants who take part in early gestation, can participate in late gestation, if they meet all inclusion criteria.\n* Good general health with no acute or chronic medical conditions. (Including only healthy participants minimizes confounding factors that could alter amino acid metabolism and ensures participant safety.)\n* Fully ambulatory and able to comply with study procedures. (Participants must be able to attend study visits and complete protocol requirements, including dietary intake and sample collection.)\n* Pre-pregnancy body mass index (BMI) between 19 and 28 kg\u002Fm² (This range excludes underweight and obese individuals, whose altered protein and amino acid metabolism could affect study outcomes.)\n* Carrying a viable pregnancy without known complications at enrollment. (Excluding pregnancy complications at baseline reduces risk to participants and supports accurate assessment of physiological amino acid requirements.)\n\nExclusion Criteria:\n\n-Pregnancy-related complications (e.g., hyperemesis gravidarum, GDM, hypertension, pre-eclampsia, anemia).\n\n(These conditions may alter metabolism and increase risk, potentially confounding study outcomes.)\n\n* History of adverse pregnancy outcomes (spontaneous abortion or preterm birth). (May reflect underlying physiological factors affecting amino acid metabolism.)\n* Multiple gestation pregnancies. (Nutritional and metabolic demands differ from singleton pregnancies.)\n* Pregnancy loss within six months of the current pregnancy. (Short intervals may affect maternal nutrient status and metabolic adaptation.)\n* Chronic metabolic, cardiovascular, neurological, genetic, or immune disorders. (These conditions may independently affect protein and amino acid metabolism.)\n* Clinically significant claustrophobia. (May interfere with study procedures requiring ventilated hood measurements.)\n* Use of alcohol, tobacco, or illicit substances during pregnancy. (Substance use affects metabolism and poses maternal and fetal health risks.)\n* Gestational weight loss greater than 1.5 kg. (May indicate inadequate nutritional status.)\n* Pre-pregnancy BMI outside 19-28 kg\u002Fm². (Extremes of BMI are associated with altered protein metabolism.)",true,"FEMALE","20 Years","40 Years",{"count":21,"type":22},40,"ESTIMATED","INTERVENTIONAL",[25],"NA","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.
