What Is Beta-Glucan?
Beta-glucan is a group of soluble dietary fibers that are found in whole grains such as oats and barley, certain types of mushrooms, yeast, and seaweed. As a polysaccharide sugar, Beta-glucans are distinguished by their beta-glycosidic linkage structure that the human body recognizes and interacts with.
A String of Glucose Units With Different Branch Points.
It is a complex carbohydrate composed of glucose molecules arranged in a distinct pattern with beta-type linkages, making it stand out among other carbohydrates. This potent compound is abundantly found in various natural sources, with fungi (such as Shiitake and Reishi mushrooms) and certain grains (like oats and barley) being the most notable providers. When consumed, beta glucan interacts with specific receptors on immune cells, triggering a cascade of responses that enhance the immune system’s vigilance and effectiveness in combating infections and illnesses.
Beyond its immune-boosting capabilities, beta-glucan also shows promise in supporting heart health. Research suggests that regular intake of beta-glucan can lower cholesterol levels, particularly LDL cholesterol, often known as “bad cholesterol.” By forming a gel-like substance in the digestive tract, beta-glucan interferes with cholesterol absorption, potentially reducing the risk of heart disease. Additionally, the compound displays antioxidant and anti-inflammatory properties, further contributing to its potential in protecting cells from oxidative stress and chronic diseases like cancer and neurodegenerative conditions. As a natural powerhouse with a range of health benefits, incorporating beta glucan-rich foods or supplements into a balanced diet could be a promising step towards improving overall well-being.
What are the Health Benefits of Beta-Glucans?
- Heart Health: Beta-glucan, especially from sources like oats and barley, can help lower LDL (“bad”) cholesterol levels, contributing to improved cardiovascular health. [PMC2663451]
- Reduces Cancer Risk and Helps In Cancer Treatment: Beta-glucans are able to reduce the risk of cancer by enhancing the body’s immune response, which helps in detecting and eliminating cancerous cells more effectively. [PMC7016572]
- Supports Immune System: Beta-glucan can help boost your immune system, especially those derived from yeast and mushrooms. It helps your body to fight off infections and diseases more effectively. [PMC3236515]
- Digestive Health: Being a type of fiber, beta-glucan aids in maintaining a healthy digestive system. It helps promote regular bowel movements and contributes to good gut health. [PMID: 34709792]
- Blood Sugar Control: Beta-glucan can slow down food digestion, which results in a more gradual rise in blood sugar levels after meals. This property can be particularly beneficial for people with diabetes. [PMC2663451]
- Weight Management: Beta-glucan may aid in weight control by creating a feeling of fullness, which can discourage overeating.[PMC3236515]
- Covid-19 Immune Therapy: Certain extracts from the Shiitake mushroom can help calm down our body’s overactive immune response, which can cause severe lung damage in coronavirus pneumonia. Different extracts work differently, but they all show promise in helping to prevent the harmful effects seen in severe COVID-19 cases. [PMC7211630]
Types of Beta-Glucans
Not all beta-glucans are the same. They come in different types with unique molecular linkages, each offering distinct health benefits. Understanding these linkages can shed light on the range of health advantages offered by each type of beta-glucan. The three primary types are 1,3 beta glucan, 1,6 beta-glucan, and 1,4 beta-glucan.
Beta-1,3 / 1,6-Glucan: Immunomodulation
Beta-1,3/1,6-glucan is a prominent type of beta-glucan found primarily in the cell walls of bacteria and fungi, with the number referring to the specific bonding pattern between the glucose units in the polymer. Health benefits associated with this type of beta-glucan include its potent immunomodulatory effects, where it helps boost the immune system’s response to infections and diseases. The 1,3-1,6-beta-glucans are considered to be the best biological response modifiers and have immunogenic properties [PMC7188827]
Some primary food sources of Beta-1,3/1,6-glucan include baker’s yeast, shiitake mushrooms, and some types of seaweed. From a chemical standpoint, the structure of beta-1,3/1,6-glucan consists of a backbone of glucose residues linked by β-1,3-glycosidic bonds, with branches connected by β-1,6 linkages, thus the moniker Beta-1,3/1,6-glucan.
Beta-1,3 / 1,4-Glucan: Blood Sugar, Cholesterol, and Gut Health
Another significant type is the Beta-1,3 /1,4-glucan, which is prevalent in plants, especially in cereal grains like oats and barley. It’s associated with health benefits, including reducing cholesterol levels, controlling blood sugar, and supporting gut health due to its high dietary fiber content.
Oats and barley are the primary food sources of Beta-1,3/1,4-glucan, but it can also be found in other whole grains such as wheat and rye. In terms of its chemical structure, Beta-1,3/1,4-glucan consists of glucose monomers linked by β-1,4 bonds in the main chain and β-1,3 bonds at the branching points, making it a unique complex carbohydrate.
Beta-1,4-Glucan: Gut Health
Beta-1,4-glucan, otherwise known as cellulose, is the most common organic compound and the primary structural component in the plant kingdom. This type of beta-glucan forms the structural integrity of plant cells. Humans lack the necessary enzymes to digest it; however, it provides dietary fiber that promotes digestive health.
Primary sources include all plant-based foods, with significant amounts in vegetables, fruits, whole grains, and legumes. The chemical structure of Beta-1,4-glucan is straightforward, with glucose units joined solely by β-1,4-glycosidic linkages, which gives cellulose its high tensile strength.
As you can see, beta-glucans are a diverse group of polysaccharides with different types of linkages that offer unique health benefits. From immune-boosting and immune-modulating effects to cholesterol reduction, these natural compounds play a vital role in supporting overall well-being.
Beta Glucan And Chronic Inflammatory Response Syndrome (CIRS)
What is CIRS?
Mold Illness and Lyme disease are the top 2 causes of CIRS. Chronic Inflammatory Response Syndrome (CIRS), also known as biotoxin illness, is a multi-system, multi-symptom condition triggered by exposure to certain biological toxins. Often these toxins originate from molds found in water-damaged buildings, but they can also come from tick-borne illnesses, spider bites, or certain types of fish consumption.
CIRS happens when the immune system fails to “turn off” after the initial threat is gone. This leads to prolonged inflammation that can affect nearly every system in the body. Common symptoms can include fatigue, memory problems, joint and muscle pain, difficulty concentrating, gastrointestinal issues, and more. It’s a complex illness that often requires a multifaceted treatment approach and can be hard to diagnose due to its wide array of symptoms.
How Does Beta Glucan Help CIRS?
CIRS is primarily an issue of a dysregulated immune system, where the body remains in a state of chronic inflammation long after being exposed to a triggering biotoxin. Beta-glucans is thought to help by essentially ‘re-training’ the immune system. They do this by interacting with certain immune cells, like macrophages and dendritic cells, and stimulating them to respond in a more controlled, appropriate way.
Specifically, beta-glucans bind to a receptor on these cells called Dectin-1. This binding process initiates a cascade of events within the immune cell that triggers a more balanced immune response, including the activation of immune modulators. In essence, beta-glucans might help ‘reset’ the immune response to be less hyperactive and more measured, which could help reduce the chronic inflammation seen in CIRS.
Beta Glucans could be a significant player in managing Chronic Inflammatory Response Syndrome (CIRS), a condition caused by exposure to biotoxins from certain molds. This syndrome can cause a variety of symptoms due to a constant inflammatory response in those who are susceptible.
An essential part of our immune system’s defense against fungal infections, including those associated with CIRS, are Dectin-1 receptors. These receptors live on our immune cells—particularly on specialized ones called macrophages and dendritic cells—and they have a unique ability: they recognize and bind to components found in the cell walls of fungi, such as beta-glucans.
When these Dectin-1 receptors interact with fungal components, it triggers a chain of events within our immune cells. This chain of events leads to a variety of immune responses, including creating inflammatory molecules, activating a process called phagocytosis—which helps in getting rid of fungal cells—and releasing immune modulators that oversee the overall immune response.
In cases of CIRS, these Dectin-1 receptors can recognize and respond to the fungal components related to mold exposure. The activation of these receptors can contribute to the continuous immune response and inflammation seen in CIRS. Thus, the role of beta-glucans in this process suggests their potential benefits as a supplement in managing conditions like CIRS.

Is Beta-Glucan Safe?
Beta-glucan supplements are recognized as being very safe based on their long history of use in foods and nutritional supplements as well as countless clinical studies.
Medication Interactions with Beta-Glucan
- Blood Sugar Lowering Medications: Beta-glucan can slow down digestion, which can help control blood sugar levels. If you’re taking medication to lower blood sugar, adding beta-glucan could cause your blood sugar to go too low.
- Cholesterol Lowering Medications: Beta-glucan is known to help lower cholesterol levels. When taken in combination with cholesterol-lowering medications, it could potentially enhance the effect of these drugs, leading to overly low cholesterol levels.
Supplement Interactions with Beta-Glucan:
- Fiber Supplements: Since beta-glucan is a type of fiber, taking it with other fiber supplements could lead to an excessive intake of fiber. This might result in gastrointestinal discomfort, such as bloating, gas, or changes in bowel movements.
- Supplements That Lower Blood Sugar: Beta-glucan can slow digestion, which helps control blood sugar levels. If you’re taking other supplements known to lower blood sugar levels, like cinnamon or fenugreek, adding beta-glucan could enhance these effects.
