A comprehensive look at the effects of probiotics on seasonal allergies suggests these friendly bacteria may be a helpful treatment.
Probiotics are the healthy bacteria found in the body and are linked to healthy digestion. Scientists also point to such good microorganisms as being beneficial for the
immune system, Live Science noted.
Looking at 23 previous studies, researchers found that those with hay fever may receive some relief from symptoms by taking probiotics, in addition to an improved quality of life, Live Science reported. In 17 of the trials, participants experienced improvement in at least one measurement in relation to seasonal allergies when taking supplements or foods with probiotics compared with those who took a placebo.

Data differences are likely due to variations in strains of probiotics used, dosage amounts, and timing of consumption, according to Live Science.
Fitness magazine recommended taking Lactobacillus casei probiotics, which are commonly found in yogurt. One study found those who took them had lower amounts of an antibody that causes histamine to be released. This neurotransmitter promotes the symptoms of many allergies, including a runny nose, watery eyes, and sneezing.
In cases of seasonal allergies, when the body is exposed to a foreign substance, for example pollen, the body recognizes the invader, and it triggers the immune system to kick into gear,
according to CulturedFoodLife.com. In doing so, the body sends out substances to create inflammatory responses. Allergic reactions tend to result from the stress of this process.
Getting an intake of good bacteria helps the body to absorb nutrients better, decreasing the strain placed on the body when exposed to invaders, CulturedFoodLife.com noted.

Seasonal allergies are typically treated using a variety of medications, including antihistamines, decongestants, and steroid nasal sprays, Live Science noted. Researchers said it was not likely probiotics would come to replace already-existing methods for treatment.
Medical Daily said the most effective means for treating these allergies has shown to be nasal sprays. Whatever a patient decides to use, however, it is recommended to speak with a doctor before beginning to take a medication.
Scientists told Live Science more research is needed to fully understand the effect probiotics have on the immune system as well as the particulars in treating hay fever and seasonal allergies.
