Asthma supplement trial aims to ease breathing and anxiety in kids

This study is testing whether a natural supplement called 5HTP can improve breathing and reduce anxiety in children aged 8-18 with mild to moderate asthma and allergies. About 20 participants will be randomly assigned to take either 5HTP or a placebo, then switch groups later. The trial lasts about 12 weeks with 5 visits to measure lung function, blood markers, and anxiety symptoms.
