Phenylalanine Needs Over the Menstrual Cycle Study
We are looking for healthy females (ages 20-35) to participate in our nutrition study. This study aims to determine the phenylalanine requirements during the phases of the menstrual cycle. Phenylalanine is an essential amino acid, meaning it cannot be made naturally in the body and must be eaten in the diet. It is necessary for protein synthesis, immunity, and other important cellular functions. Consuming an adequate amount daily is crucial for maintaining overall health. Dietary phenylalanine requirements have not yet been determined in the female body and, therefore, this research will improve dietary guidelines for females.

Leucine Pregnancy Nutrition Study
We are looking for healthy pregnant women in early (11–20 weeks) and late (31–40 weeks) gestation to participate in a research study examining dietary leucine requirements. Leucine is an essential amino acid that plays an important role in protein metabolism and supporting tissue growth. During pregnancy, nutritional needs increase, but leucine requirements have not been directly studied in pregnant individuals. This study aims to better understand these needs and contribute to improving dietary recommendations for maternal and fetal health.

Defatting Human Milk for Critically Ill Infants Study
We are looking for individuals with a term pregnancy who are under 1 year postpartum to donate their human milk. The aim of this study is to create a simple method to defat milk. Infants with a condition called chylothorax cannot safely digest fat, and eat a diet of low fat formula during treatment. We want to create a new way for families to continue providing human milk to their infants in the hospital and at home.

Lactation Nutrition Study
We are looking for those who are exclusively breastfeeding to participate in our study. This aim of this research is to determine maternal lysine requirements while breastfeeding. Lysine is an essential amino acid required for protein synthesis and other aspects of health. This research is important because current dietary recommendations for protein and amino acids during lactation are estimations and have not been evaluated.

Leucine is an essential amino acid (cannot be made naturally in the body) and is necessary for protein synthesis, and other important cellular functions. Consuming an adequate amount daily is crucial for maintaining overall health. Dietary leucine requirements have not been previously determined in women, and therefore, this research will improve dietary guidelines for women.

Creatine Study in Healthy Adult Men
Protein in food contains an amino acid called methionine. Amino acids are building blocks of protein and are essential in almost all bodily functions and structures. Some rare genetic diseases do not allow for proper digestion of amino acids and need to be restricted in the diet. We want to investigate if giving added creatine (nutritional supplement) will affect the digestion of methionine in the body.

Pregnancy Nutrition Study
Amino acids are the building blocks of proteins, which our bodies use in almost every cell. Some amino acids are indispensable, including tryptophan. Tryptophan, in particular, is involved in immunity and neuropsychiatric conditions, as it is essential for serotonin production, which is important for mood and sleep. However, tryptophan requirements have not been experimentally determined during pregnancy. Therefore, we aim to estimate tryptophan needs during pregnancy.
