Probiotics May Improve Quality of Life for People with Allergies
Allergies affect quality of life for nearly 50 million Americans. A recent study suggests that taking a combination of three different probiotics may help improve quality of life for people with seasonal allergies.
Participants in the study included 173 people with seasonal allergies who were given either a combination of Lactobacillus gasseri KS-13, Bifidobacterium bifidum G9-1, and B. longum MM-2 (for a total of 3 billion colony-forming units) or a placebo daily for eight weeks during allergy season.
At the conclusion of the study, the researchers noted a 0.70 improvement from baseline to pollen peak on the Mini Rhinoconjunctivitis Quality of Life Questionnaire in the probiotic group. There was no similar change in the placebo group. They also noted improvements in immunoglobin E concentrations and regulatory T cells in the probiotic group, while the placebo group failed to reach a statistically significant change.
Researchers from the University of Florida conducted the study. It was published on February 22, 2017, in The American Journal of Clinical Nutrition.
This study adds to a growing body of research that suggests a strong connection between probiotics, gut health, and allergies. Previous studies suggest that people with allergies have less diverse gut microbiota, which probiotics can improve. Others suggest that early probiotic supplementation may even ward off allergies later in life.
