Strengthening Your Defense System: The Impact of Probiotics on Allergies and Asthma

In recent years, there has been growing interest in the potential of probiotics to support overall health and well-being. Probiotics are live bacteria and yeasts that are beneficial to our health, particularly our digestive system. They can be found naturally in certain foods and also come in the form of supplements.

While probiotics are most commonly known for their positive effects on gut health, there is emerging evidence suggesting that their benefits extend beyond digestion. Research now suggests that probiotics may play a significant role in preventing and managing allergies and asthma, two conditions commonly associated with an overactive immune system.

The Link Between Probiotics and Allergies

Allergies occur when the immune system overreacts to harmless substances, such as pollen, pet dander, or certain foods. This exaggerated immune response leads to symptoms like sneezing, itching, and wheezing. Studies have indicated that probiotics may help reduce the severity and frequency of allergic reactions by modulating the immune response.

One study published in the journal International Archives of Allergy and Immunology found that supplementation with specific strains of probiotics reduced the risk of developing eczema and allergic rhinitis in children at high risk for these conditions. Another study published in the Journal of Allergy and Clinical Immunology showed that pregnant women who consumed probiotic-rich yogurt during their pregnancy had a decreased risk of their children developing allergies in early childhood.

While more research is needed to fully understand the mechanisms behind this link, it is believed that probiotics can influence the production of immune cells and substances that regulate immune responses. By promoting a more balanced immune system, probiotics may help prevent and alleviate allergic reactions.

Probiotics and Asthma: Strengthening Your Defenses

Asthma, a chronic respiratory condition, is characterized by inflammation and narrowing of the airways, which can make breathing difficult. Managing asthma often involves medications to control symptoms and reduce inflammation. However, emerging research suggests that probiotics may also play a role in improving asthma control.

A study published in the European Journal of Clinical Nutrition found that children with asthma who were given probiotics experienced improved lung function and reduced symptoms compared to those who did not receive probiotic supplementation. Another study published in Pediatric Allergy and Immunology showed that children with asthma who regularly consumed probiotic-rich milk had fewer and milder asthma exacerbations.

It is hypothesized that probiotics may help reduce asthma symptoms by modulating the immune response and reducing airway inflammation. Probiotics may also support the growth of beneficial bacteria in the gut, which can further enhance immune function and reduce allergic responses.

Choosing the Right Probiotic for Allergies and Asthma

Not all probiotics are created equal, and different strains of bacteria may have varying effects on allergies and asthma. When considering probiotic supplementation, it is important to choose products that contain strains that have been specifically studied for their potential benefits in these conditions.

Lactobacillus and Bifidobacterium are two common genera of bacteria that have shown promise in reducing allergy symptoms. It is advisable to look for probiotic products that contain these specific strains or consult with a healthcare professional for personalized recommendations.


Probiotics offer a promising avenue for supporting immune health and reducing the risk of allergies and asthma. While further research is needed to fully understand their role in these conditions, the existing studies indicate that probiotics can be a valuable addition to the management and prevention of allergies and asthma.

If you or your child suffer from allergies or asthma, consider adding probiotics to your daily routine. However, always consult with a healthcare professional before starting any new supplements or making significant changes to your medical management.
