Testing a multi-strain probiotic for year-round allergies
Part of Ear, nose & throat, Immune system & allergy, Lungs & breathing clinical trials.
This trial tests if a special probiotic blend can help people with year-round allergic rhinitis (nasal allergies) caused by common indoor allergens like dust mites, cat, or dog dander. Volunteers will take the probiotic daily and track their symptoms.
