NCT ID NCT07308288
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a dietary supplement containing immune-supporting nutrients and postbiotics in 40 children aged 5–12 with asthma and/or allergic rhinitis. The goal was to see if the supplement could improve symptom control over 6 months. Researchers also looked at changes in immune cells to understand how the supplement might work.
