In some parts of the country (especially here in Florida where I live) allergy season is in full swing. So many people are suffering with congested sinuses, stuffy noses, and feeling like, well, not so great. Over 11 million people in the United States are diagnosed with allergic rhinitis, or hay fever—what most people simply call allergies—each year. I am sure there are many more people who do not get officially diagnosed, adding to this staggering number.
A recent study published in the European Journal of Clinical Nutrition found that people taking the probiotic Lactobacillus paracasei daily for five weeks in addition to their usual allergy medication had improved quality of life along with improved ocular symptoms (less watery, itchy, red, and swollen eyes). Improvement in specific nasal symptoms was not found, however.
“Probiotic foods or food supplements seem to be popular and widely used by subjects suffering from allergic rhinitis, however, a study under real-life conditions and in subjects receiving a medicinal treatment was needed,” noted the researchers. While they did find a benefit of the probiotic, more studies will be needed to determine whether the addition of other strains will increase the effect.
A number of probiotic strains have already been studied in people with allergic rhinitis, but most of them have been single strain studies with mixed results. Researchers have begun to look at multiple strain formulas for allergies, but we are still in the early stages of research. My hunch is that the multi-strain probiotic formulas will be more effective because they target a wider range of immune functions. I will keep you posted as I learn more.
