Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this research study is to examine if the use of antioxidant supplements impacts exercise intolerance in people with CF.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Exercise intolerance is a critical problem for people with cystic fibrosis (CF) able to predict hospitalization independent of lung function. Recent studies have suggested that certain supplements may help improving exercise intolerance.
