Probiotics help seasonal allergy suffers

In a double-blind, placebo-controlled, parallel, randomized clinical trial, 173 participants with seasonal allergies received either a probiotic (Lactobacillus gasseri KS-13, Bifidobacterium bifidum G9-1, and B. longum MM-2) or placebo during spring allergy season for 8 weeks. The probiotic group reported an improvement in the Mini Rhinoconjunctivitis Quality of Life Questionnaire (MRQLQ) global score from baseline to pollen peak when compared with the placebo group.
