SANDIA Trial Summary

This trial is testing whether L-citrulline, an L-arginine donor, can improve the asthma control and lung function in obese late onset asthmatics by increasing the L-arginine/ADMA ratio, FeNO levels, and reducing bronchoconstriction and lung inflammation.

Who is the study for?
This trial is for adults with asthma that started after childhood, who are obese (BMI >= 30), and have a history of poor response to inhaled steroids. They should be on regular asthma medication but not have had an exacerbation or used systemic corticosteroids in the last month. Smokers or those with recent lung infections aren't eligible.Check my eligibility
What is being tested?
The study tests if L-citrulline improves asthma control and lung function in obese adults with late-onset asthma. Participants will take either L-citrulline or a placebo over two 8-week periods, separated by a washout period, to compare effects on their condition.See study design
What are the potential side effects?
Potential side effects may include discomfort at the supplement intake site, gastrointestinal issues like upset stomach or diarrhea, and changes in blood pressure. Allergic reactions could occur but are less common.
