Your Body Has a Built-In Shield: Here is How to Support It Naturally

Natural immune defence is your body's remarkable, layered system for identifying and neutralising threats before they make you sick. If you are looking to strengthen it naturally, functional mushrooms are among the most researched natural tools available for supporting both your innate and adaptive immune responses. These fungi have been used for centuries, but modern science is finally catching up to explain how they interact with our biological pathways. At Eversio Wellness, we focus on providing the highest quality extracts of Turkey Tail, Chaga, and Reishi to help you maintain this vital internal balance.
Here is a quick overview of how functional mushrooms support natural immune defence:
- Turkey Tail contains beta-glucans and polysaccharides like PSK and PSP that may help modulate immune activity and support gut health.
- Chaga is rich in antioxidants that may help reduce oxidative stress and support the body's natural defences against environmental stressors.
- Reishi acts as an adaptogen, supporting immune regulation and helping the body manage stress responses that can otherwise suppress immunity.
- Beta-glucans are the key active compounds in functional mushrooms that bind to receptors in gut-associated lymphatic tissue to help prime immune cells.
- Whole fruiting body extracts deliver higher concentrations of these active compounds compared to mycelium-based products, making quality and extraction method critical.
Your immune system is not a single organ or a switch you can simply flip on. It is a complex, intelligent network of cells, proteins, and biological responses working around the clock to keep you healthy. The innate system responds immediately to threats, while the adaptive system builds targeted, long term defences. Functional mushrooms may help support both arms of this process by acting as biological response modifiers.
I am Brandi Garden, co-founder of Eversio Wellness, and my personal journey through autoimmune challenges and burnout led me to explore the science behind natural immune defence. That lived experience, combined with years of research into traditional and modern mycology, shapes everything we do at Eversio. We believe in transparency, potency, and the extraordinary potential of functional mushrooms to change lives.
Simple natural immune defence glossary:
The Science of Natural Immune Defence and Functional Mushrooms
To understand how we can support our bodies, we first need to look at how the immune system actually functions. Think of your natural immune defence as a two part security team. The first team is the innate immune system, which is your body's rapid response unit. It includes physical barriers like your skin and mucous membranes, as well as specialised white blood cells that act like a general patrol.
The second team is the adaptive immune system. This group is more like a specialised detective unit that takes a little longer to get moving. It usually activates four to seven days after a threat is detected, but it is incredibly precise. It uses T cells and B cells to identify specific invaders and creates antibodies to remember them for future encounters.
Functional mushrooms are fascinating because they are considered biological response modifiers. This means they do not just boost the system in one direction. Instead, they help the body's own defence mechanisms work more efficiently. Research suggests that certain compounds in mushrooms can help train these immune cells to be more alert and responsive (Wasser, 2017).
When we talk about the efficacy of these fungi, the extraction process is vital. Many people are surprised to learn that the beneficial compounds are locked inside the tough cell walls of the mushroom. These walls are made of chitin, which is the same material found in the shells of crustaceans. Since humans cannot digest chitin easily, we use dual extraction methods to make these nutrients bioavailable.
To learn more about how this works, you can read Everything you need to know about functional capsules. This process ensures that the beta-glucans and other active metabolites are released from the fungal matrix. Without proper extraction, the mushroom powder would simply pass through the digestive tract without providing significant benefit.

How Mushrooms Support Your Natural Immune Defence
The way functional mushrooms interact with our natural immune defence is through a process often called immune surveillance. Imagine your immune cells as a fleet of security guards. Mushrooms help prime these guards, making them better at spotting intruders. Key players in this process include natural killer cells and macrophages.
Natural killer cells are a type of white blood cell that roam the body looking for cells that have changed or become compromised. Macrophages are the big eaters of the immune system that engulf and destroy foreign particles. Studies have shown that the polysaccharides found in mushrooms can stimulate the activity of these cells, enhancing the body's innate response (Guggenheim et al., 2014).
Furthermore, mushrooms may influence cytokine production. Cytokines are small proteins that act as messengers, telling the immune system when to ramp up a response and when to calm down. By helping to modulate these signals, functional mushrooms support a balanced immune environment. This is crucial because an overactive immune response can be just as problematic as an underactive one.
The Role of Beta-Glucans in Natural Immune Defence
If there is one term you should remember when it comes to mushrooms and natural immune defence, it is beta-glucans. Specifically, we look for 1,3/1,6 beta-D-glucans. These are the complex sugars found in the cell walls of the mushroom fruiting body. They are the primary active ingredients responsible for the immunomodulating effects we seek (Vetvicka & Vannucci, 2019).
Unfortunately, not all mushroom supplements are created equal. Many products on the market use mycelium on grain. This is essentially the root system of the mushroom grown on a bed of rice or oats. The problem is that the final product often contains more starch from the grain than actual mushroom compounds.
At Eversio Wellness, we only use the whole fruiting body to ensure our extracts are starch free and high in potent beta-glucans. The bioavailability of these compounds is also a major factor. Through dual extraction using both hot water and alcohol, we are able to pull out both the water soluble beta-glucans and the non-water soluble compounds like triterpenes. This ensures that when you take a capsule, your body can actually absorb and utilise the nutrients to support your natural immune defence.

Turkey Tail: The Ultimate Defender
When it comes to natural immune defence, Turkey Tail is often considered the gold standard. It has been used for centuries in traditional practices and is now one of the most extensively studied mushrooms in modern science. Two specific compounds found in Turkey Tail, known as PSK and PSP, are highly regarded for their ability to support immune health.
Turkey Tail is also an incredible source of prebiotic fibre. We are learning more every day about the gut-immune connection. Since a vast majority of your immune system is located in your gastrointestinal tract, keeping your microbiome healthy is essential. The prebiotics in Turkey Tail nourish the beneficial bacteria in your gut, which in turn helps regulate your overall immune response.
By supporting the health of the gut lining and the diversity of the microbiome, Turkey Tail helps maintain a strong first line of defence. This holistic approach is why many people choose to include it in their daily wellness routine. For a deeper dive into these benefits, check out The immune benefits of Turkey Tail mushrooms.
The Importance of Adaptogens in Immunity
Stress is a significant factor that can compromise your natural immune defence. When the body is under chronic stress, it produces higher levels of cortisol. This hormone can suppress the effectiveness of the immune system by lowering the number of lymphocytes available to fight off threats. This is where adaptogenic mushrooms like Reishi play a vital role.
Adaptogens are natural substances that help the body adapt to stressors and exert a normalising effect upon bodily processes. By supporting the adrenal glands and the nervous system, these mushrooms may help prevent the immune suppression that often follows periods of high stress. This creates a more resilient foundation for your overall health and well-being.
Furthermore, the antioxidant properties of mushrooms like Chaga help to protect cells from oxidative damage. Oxidative stress occurs when there is an imbalance between free radicals and antioxidants in the body. By providing a rich source of antioxidants, functional mushrooms may help maintain the integrity of immune cells, allowing them to function at their peak capacity.

Chill Now: Organic Reishi Mushroom 15:1 Dual Extract Capsules

Stress is one of the biggest enemies of a strong immune system. When we are chronically stressed, our bodies produce cortisol, which can suppress immune function over time. This is where Reishi comes in, as it is a powerful adaptogen that helps the body stay in balance.
Our Chill Now capsules use a 15:1 dual extract, providing a high concentration of both beta-glucans and triterpenes. Triterpenes are the compounds responsible for Reishi's bitter taste and its ability to support the nervous system. By helping you manage stress and improve sleep quality, Reishi indirectly but powerfully supports your natural immune defence. We recommend taking 1-2 capsules daily for best results.
