5 Surprising Ways Probiotics Boost Your Immune System

Probiotics are live bacteria and yeasts that are good for your health, especially for your digestive system. They are commonly found in supplements and fermented foods such as yogurt, kefir, kimchi, and sauerkraut. While probiotics have long been known to improve digestion, studies have found that they play a crucial role in boosting your immune system in ways you might not have expected. Here are the top 5 surprising ways probiotics boost your immune system:

1. They Enhance the Function of Your Natural Killer Cells

Your natural killer (NK) cells are a type of white blood cell that play a critical role in killing viruses and cancer cells. Studies have found that probiotics can enhance the function of your NK cells and increase their production. This means that your body will be better equipped to fight off infections and diseases.

2. They Reduce the Risk of Respiratory Infections

Probiotics have been found to reduce the risk of respiratory infections such as the common cold and flu. One study found that taking a specific strain of probiotics reduced the incidence of respiratory infections by as much as 42%. This is because probiotics boost the production of antibodies, which are proteins that help your body fight off infections.

3. They Protect Against Allergies

Allergies occur when your immune system overreacts to a harmless substance such as pollen or dust. Studies have found that probiotics can reduce the risk of developing allergies by enhancing the production of regulatory T cells, which help to calm down your immune system and prevent it from overreacting.

4. They Improve Vaccine Effectiveness

Vaccines work by stimulating your immune system to produce antibodies against a specific disease. Studies have found that probiotics can enhance the effectiveness of vaccines by boosting the production of antibodies. This means that you will be better protected against diseases such as influenza and pneumococcal disease.

5. They Enhance Gut-Brain Communication

Your gut is often referred to as your second brain because it contains millions of neurons that communicate with your central nervous system. Studies have found that probiotics can enhance gut-brain communication, which can improve your mood and reduce stress. This is because probiotics increase the production of neurotransmitters such as serotonin, which is often referred to as the “happy hormone”.

Conclusion

Probiotics are essential for maintaining a healthy immune system. They enhance the function of your natural killer cells, reduce the risk of respiratory infections and allergies, improve vaccine effectiveness, and enhance gut-brain communication. While probiotics are commonly found in supplements and fermented foods, it is important to choose a high-quality product that contains the right strains of bacteria. Consult with your doctor before starting any new supplement or dietary plan.
