A study from the University of Florida, in Gainesville, has found that the probiotic combination of lactobacilli and bifidobacteria (sold as Kyo-Dophilus) helps relieve the symptoms of seasonal allergies.
Researchers split 173 healthy adults with mild seasonal allergies into two groups during the height of the spring allergy season. The first group was given the probiotic combination, while the other group received a placebo. The subjects filled out a weekly online survey for eight weeks about their allergy symptoms and discomfort levels. The probiotic combination resulted in fewer allergy-related nasal symptoms plus quality-of-life improvements
