Beta Glucan for The Immune System

Our immune system’s first line of defense against germs and pathogens entering the body is known as the innate immune system.

This is extremely important in fighting off viral and bacterial infections found in the mucosal cell surface. 1

Clinical studies have proven that incorporating natural supplements like Beta Glucans into your daily routine can support your immune health.

Reduced Frequency of Common Colds and Flu

One significant advantage of having a robust immune system is experiencing fewer instances of common colds and flu.

With improved immune support, your body becomes more efficient at defending itself against viruses responsible for these ailments.

This not only leads to better overall health but also contributes to increased productivity in daily activities.

Lower Risk of Chronic Diseases

• Cancer: A well-functioning immune system plays an essential role in preventing cancerous cells as well as acting as an anti-tumor treatment. 1.1

• Type 2 Diabetes: Research has shown that individuals with healthier immune systems are less likely to develop type 2 diabetes, as their bodies can effectively manage blood sugar levels. 2

• Rheumatoid Arthritis: By maintaining a balanced inflammatory response, a healthy immune system may help reduce the risk or severity of autoimmune disorders such as rheumatoid arthritis. 3

Incorporate natural supplements that are known for their ability to boost our defenses, like Beta Glucan derived from cell walls found in plants such as oats and barley.

To gain further insight into how to keep our immune system functioning optimally, let's look at the common signs of an impaired immune response.

Frequent Respiratory Infections

People with weakened immune systems are more prone to catching respiratory illnesses.

Their body's defense mechanisms struggle to fight off invading pathogens effectively.

If you are regularly catching respiratory illnesses or having difficulty recovering, it could suggest that your immune system needs some assistance.

Constant Tiredness or Lethargy

A persistent feeling of tiredness or lethargy could also signal a compromised immune system.

The body relies on its immune function for energy production and overall vitality; when the immune system is not functioning optimally due to factors like stress or poor nutrition, it can result in chronic fatigue. 4

It is essential to pay attention to your energy levels and address any potential underlying causes contributing to ongoing exhaustion.

Digestive Issues

A significant portion of our immune health resides within our gut microbiome - the collection of beneficial bacteria living in our intestines that aid digestion and nutrient absorption while protecting against harmful pathogens. 5

When there is an imbalance in this delicate ecosystem due to factors like antibiotic use or poor diet choices (e.g., high sugar intake), it can lead to digestive issues and a weakened immune system.

A healthy microbiome helps produce the antibodies we need to fight off disease and infection.

Slow Wound Healing

When the immune system is compromised, it may struggle to repair damaged tissues effectively or ward off infections at the wound site.

If you notice that cuts or scrapes are taking longer than usual to heal, it could be a sign that your immune function needs improvement.

The effects of β-glucan have been shown to enhance immune function by activating immune cells and promoting the production of cytokines - proteins that help regulate the immune response.

Research has also suggested that beta glucan may have anti-inflammatory and antioxidant properties, further supporting their potential role in immune health.

These supplements provide essential nutrients that support various aspects of immune function while promoting overall health.

By combining vitamins, minerals, and other beneficial compounds in the right amounts, individuals can bolster their immune system and reduce their susceptibility to illnesses.

Vitamins C and D for Infection Prevention

Vitamin C is a powerful antioxidant known for its role in supporting a healthy immune system.

It aids in the production of collagen, which is crucial for wound healing, and protects cells from free radical damage. 6

Additionally, vitamin C enhances white blood cell function and has been shown to shorten the duration of colds when taken regularly.

Vitamin D, on the other hand, plays a crucial role in maintaining strong bones and teeth but also contributes to immune health. 7

Research suggests that people with low levels of vitamin D are more susceptible to infections, such as respiratory illnesses like flu or pneumonia, due to their reduced ability to fight off pathogens. 8

Probiotics for Gut Health

A large portion of our immune system resides within our gut, making it essential to maintain proper digestive health through balanced gut flora (the good bacteria). 9

Probiotic supplements containing live cultures help promote this balance by introducing beneficial bacteria into your gastrointestinal tract which supports digestion along with aiding nutrient absorption hence boosting immunity against harmful microbes.

• Lactobacillus and Bifidobacterium are two common strains of probiotics known for their positive impact on gut health. 10

• Foods that have undergone fermentation such as yogurt, kefir, sauerkraut, and kimchi provide natural sources of probiotics that can help to enhance digestive function as well as bolster immune system health.

• Foods rich in prebiotics include garlic, onions, leeks, bananas, and whole grains.

• Zinc is an essential mineral that plays a crucial role in immune cell development and function and can be found in oysters, red meat, poultry, and beans.

Research has shown that Beta Glucans can help improve immune function in a variety of ways, including:f

• Enhancement of Natural Killer (NK) Cell Activity: NK cells are essential components of our immune system that target cancerous or virus-infected cells.

Studies suggest that beta glucan supplementation can enhance NK cell function, providing additional support in combating various health threats.

Modulation of Inflammation: Chronic inflammation is associated with numerous health issues, including heart disease and autoimmune disorders.

Beta Glucans are soluble fibers that can naturally slow down the food transit time from the initial intake through the intestinal tract.

Therefore, food and supplement sources of Glucans can help to maintain balanced cholesterol and blood sugar levels.

Glucan stimulates the activation of monocytes, which are a type of immune cell also known as macrophages that roam through the bloodstream, performing tasks such as initiating various immune reactions.

Beta glucan also plays an important role in promoting the activity of lymphocytes, white blood cells known as Th1 and Th2 effectors. 11

Yeast-based beta-glucans offer a distinct and potent approach to boosting the inflammatory and antimicrobial capabilities of innate immune cells.

These substances prime your immune cells to respond promptly to potential dangers, leading to reduced risk and strengthened immune defense.

The immune system plays a vital role in protecting the body from various pathogens, including those responsible for upper respiratory infections. 12

These infections can be caused by viruses or bacteria and often result in symptoms such as coughing, sneezing, sore throat, and nasal congestion.

With the help of beta-glucan supplements, it is possible to enhance the body's natural defenses against these common ailments.

Stimulating White Blood Cells and Macrophages

In addition to a variety of independent studies, research has revealed that Beta Glucan can activate WBCs like neutrophils and macrophages, aiding in the body's immune response against disease. 13

A study published in the Journal of Nutrition & Metabolism demonstrated that participants who took beta-glucan supplements experienced fewer upper respiratory tract infection symptoms compared to those taking a placebo. 14

Research conducted at the University of Louisville found that mice treated with yeast-derived beta glucan had increased survival rates when exposed to lethal doses of influenza virus compared to untreated mice.

This suggests that regular supplementation with beta glucan may provide an additional layer of protection against viral threats.

Incorporating Beta-Glucan into Your Daily Routine

To bolster your body's defenses, taking proactive measures to fortify your immune system can be a great help in avoiding sicknesses and inflammatory diseases.

Adding natural supplements such as beta-glucans to your daily regimen can help bolster immunity and promote overall well-being.

• Choose a high-quality supplement: Look for products that contain pure beta-1,3/1,6 glucan derived from yeast or fungi sources.
• Follow recommended dosages: Consult your healthcare provider or product label for appropriate dosage guidelines based on your individual needs.
• Maintain a healthy lifestyle: A well-balanced diet rich in fruits and vegetables combined with regular exercise, will further support optimal immune health.

Related to glucose levels, both oat-based and fungal beta-glucans have been shown to reduce blood glucose levels.

Cholesterol Reduction

Research studies have shown that regular consumption of beta glucans can help lower total cholesterol levels by binding to bile acids in the digestive system. 15

By binding to bile acids, beta glucans prevent the reabsorption of cholesterol into the bloodstream, thus reducing LDL ("bad") cholesterol levels.

Lipids, along with carbohydrates and proteins, make up the primary components of both plant and animal cells.

A meta-analysis found that consuming 3 grams or more of oat-derived beta-glucan per day significantly reduced total and LDL cholesterol without affecting HDL ("good") cholesterol or triglyceride levels. 16

Lowering Hypertension Risk

High blood pressure, commonly known as hypertension, is a major risk factor for heart disease and stroke. 17

Beta glucans may contribute to lowering blood pressure by improving endothelial function - which refers to how well the inner lining of blood vessels works - thereby promoting better circulation throughout the body.

As documented on PubMed, participants with mild hypertension experienced significant reductions in systolic and diastolic blood pressure after consuming a beverage containing barley-derived beta-glucan daily for six weeks. 18

Fighting Obesity

Beta glucans have been found to promote satiety (the feeling of fullness) by slowing down gastric emptying and increasing the release of appetite-suppressing hormones (source).

This effect may aid in weight management by reducing overall calorie consumption.

Additionally, some animal studies suggest that beta glucans could potentially modulate gut microbiota composition, which has been linked to obesity prevention.

Including high-fiber foods such as whole grains rich in beta glucans can effectively manage body weight and prevent obesity-related health issues.

Cholesterol Reduction

High cholesterol is a major risk factor for heart disease, which remains the leading cause of death worldwide.

Studies have shown that consuming beta-glucan-rich foods or supplements can help lower total cholesterol levels by up to 10% and reduce LDL ("bad") cholesterol by up to 15 percent. 19

Beta-glucans' capacity to bind bile acids in the digestive system, thus preventing them from being reabsorbed into the bloodstream, has been linked to their ability to lower cholesterol levels.

Lowering Hypertension Risk

Hypertension, or high blood pressure, affects millions of people globally and increases the risk of developing serious health conditions like stroke and kidney disease.

Research has demonstrated that incorporating dietary sources rich in beta glucans may help reduce systolic blood pressure, thereby decreasing hypertension risk. 20

Beta glucans may interact with nitric oxide production in endothelial cells, potentially improving vascular function and reducing arterial stiffness to reduce hypertension risk.
