Beta-glucan supplement for preventing colds in allergic rhinitis
Part of Infections, Lungs & breathing clinical trials.
This study tests if a supplement from yeast (called yeast beta-glucan) can help prevent upper respiratory infections in young adults with persistent allergic rhinitis. Participants take the supplement and are followed to see if it reduces colds and other respiratory illnesses.
