The immune system is the core of our health. However, many people often feel overwhelmed when it comes to strengthening their defenses – especially during flu season or with chronic illnesses. Postbiotics offer an effective solution to support your immune defense.
A healthy immune system starts in the gut – but why exactly?
The “good” bacteria in the gut play a central role in nutrient absorption and simultaneously support the immune system. About 70% of the immune system is located in the gut, where it directly interacts with the gut microbiota, the entirety of all microorganisms in our gut. So, if you want to support your immune system, you should start directly in the gut.
How do postbiotics support the immune system?
Postbiotics are produced through the activity of your good gut bacteria and act directly on the body. They can have anti-inflammatory properties, strengthen the gut barrier, and activate your immune system.
There are many additional functions for your immune system:
- Postbiotics, especially short-chain fatty acids like butyrate, support the health of gut cells by serving as an energy source and promoting the formation of tight junctions between gut cells. This strengthens the gut barrier, effectively reducing the entry of pathogens and harmful substances into the bloodstream. An intact gut barrier relieves the immune system because fewer inflammatory triggers occur and excessive inflammatory reactions are prevented.
- Short-chain fatty acids can also promote the production of regulatory T cells (Tregs) – a special group of immune cells that help inhibit inflammation and suppress excessive immune responses. These Tregs play an important role in maintaining immune balance and preventing autoimmune diseases.
- A healthy gut flora supports a strong immune system. Postbiotics promote the regulation of the gut flora.
- Postbiotics have an anti-inflammatory effect because they inhibit the production of pro-inflammatory molecules.
The gut is considered the center of your health. With postbiotics, you not only support your gut but also improve your immune defense by reducing inflammation and promoting the production of immune cells.
