What this study is about
Researchers are testing if adding L-citrulline to a treatment can improve asthma control and lung function in overweight adults with late-onset asthma. The trial will also investigate how obesity affects airway NO metabolism and mitochondrial function, and whether L-citrulline can modify these changes.
