Notes for this study:
In an open-label, uncontrolled pilot trial, 44 participants with asthma and obesity took 15 g of l-citrulline for 2 weeks.

There was a non-significant increase in FEV1, which was only in females, and late-onset asthma for both sexes. There was also a statistically significant improvement in forced vital capacity overall.
