Tryptophan in cornmeal for healthy adults over 60
This study tests how healthy adults over 60 process a protein building block called tryptophan found in cornmeal. It may help researchers understand how aging affects protein metabolism.

This study aims to find out how much of an amino acid called tryptophan (a building block of protein) healthy older adults need. You will be asked to follow a special diet for a short time and have blood samples taken.
This study looks at how well protein from plant-based foods works in young adults (18–39) and older adults (60–79). It aims to understand if plant proteins can meet the body's needs as we age.
This study measures how much threonine, an amino acid found in many foods, older adults need to stay healthy. Participants will follow a special diet for a short time and have blood tests.
This trial tests whether tryptophan (a natural amino acid) can improve symptoms in people with celiac disease who still have symptoms despite following a gluten-free diet. It may help by supporting an internal body signal pathway researchers believe is impaired in some people with celiac disease.
This study looks at your “meal response”—how your blood sugar and related body processes change after eating. It may help researchers understand different metabolic patterns and how to improve health or treatment strategies for older adults.
This trial tests whether a study ingredient called P24 changes how your body breaks down and uses protein from a meal. It may help researchers understand ways to support muscle health as we age.
