NCT ID NCT07218640
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how adding chia seeds (a fiber source) to your diet and dealing with stress can change the bacteria in your gut. About 60 healthy adults will take chia seeds for two months and provide stool and blood samples. The goal is to learn how lifestyle factors affect gut health, not to treat any disease.
