5HTP Regulation Of Asthma In Children: A Double-Blind Placebo Controlled Pilot Study

Study Overview

Help IU Researchers learn more about how an over the counter supplement affects asthma and mood.
The purpose of this study is to learn if taking an over the counter supplement called 5-hydroxytryptophan (5HTP) can improve breathing and anxiety symptoms related to asthma. We are seeking children 8-17 years old and young adults 18 years old that have a diagnosis of allergic asthma and appear to be worried or sad about everyday activities
Participants can make up to $150!

Study Description

- Participants will be randomly assigned to take either the supplement (5HTP) or placebo for the first half of the study and switch to the other treatment for the second half of the study.
- Participants will attend 4 study visits over the course of 12 weeks. The visits consist of a physical exam, breathing tests, a blood draw, and a nasal collection test
- Participants could receive up to $150 in gift cards as compensation for participation if they complete each visit ($50 each after Visits 2-4).
