Probiotics and the Immune System

We all know what probiotics are-the good bacteria, the tasty addition to our diet that can help improve the overall digestive health. But are they good for your immune system too? This question is commonly asked in the probiotics community but it’s rarely explained.


Gut microbiome and Immunity


Immunity is a crucial attribute of the human body for maintaining good health. One of the most striking discoveries to emerge over recent years is that the gut microbiome is critical for all aspects of immune function. 

There are nearly 100 trillion bacteria, yeast, and viruses in the body. In the gut alone, there are roughly ten times as many microorganisms. This means that there are more of these tiny organisms living in your gut than what you have in your entire body. Collectively, the tiny microorganisms living in the gut are known as the microbiome. Many of these are good ones, commonly known as probiotics, that have a symbiotic relationship with you and your body. They live in your gut, and they provide a wide array of health benefits such as:

  • Providing a form of defense mechanism against harmful bacteria and viruses.
  • Preventing bad bacteria from sticking to the wall of the intestine
  • Strengthening the delicate wall of the intestine.
  • Enhancing immune responses. 


What’s the connection between these invisible masses and our immune system?


Well, around 70% of the immune system borders your GI tract. This puts it in the perfect place to prevent harmful substances that are ingested from entering your body through your digestive system. So, now it makes perfect sense for healthcare experts to believe that good health starts in the gut. 

Therefore, if you want to boost your immune system, then keeping your gut health in tip-top shape evidently makes very good sense, evidence also shows that probiotic bacteria play an important role in this. The probiotics in the gut help the body fight harmful microorganisms before they can actually reach the immune system. One good way to keep your gut healthy is to supplement it with probiotics along with a healthy lifestyle and diet.


How probiotics boost the immune system


Studies have shown that adding probiotics to diet conveys a range of benefits for people of all ages. The effects of probiotics with how it improves digestive health and how it boosts the immune system are well-documented.

There are many ways to naturally boost good bacteria to optimize your gut health. You can do it by increasing your fiber intake or by getting enough sleep. However, we live in a fast-paced, high-stress world that doesn’t always allow this to happen. This is where probiotics supplements come in. Probiotics help keep the digestive system healthy easily and effectively. It creates a barrier of good bacteria in the gut which helps the immune system fights off any harmful microorganisms that get in the body. Without the good bacteria fighting fit, you are at more risk from picking up infections.
