How much tryptophan do healthy older adults need?
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 trial uses a simple breath test to see how well your body uses protein from a meal. It aims to understand how age and physical activity affect protein metabolism, which is important for muscle health.
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 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 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 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 study tests whether eating your meals within a shorter time window (like 8–10 hours) while adding a protein supplement can help older adults maintain muscle and health. If you are 60 or older, have a stable weight, and can adjust your eating schedule, you may be eligible.
