Journal of Tumor 2015– “Regulation of Hematopoiesis in Cancer Patients: Placebo-Driven, Double-Blind Clinical Trials of β-Glucan”- This article focuses on the effects of glucan supplementation on cancer patients in post-treatment periods to try to alleviate anemia. There was significant improvement in hemoglobin counts and erythrocytes.
This article explores the efficacy of beta glucan for improving the after-effects of cancer therapies. One major side effect of cancer and its treatments is anemia. “Hematopoiesis is the production of all types of blood cells including formation, development, and differentiation of blood cells. Prenatally, hematopoiesis occurs in the yolk sack, then in the liver, and lastly in the bone marrow. In the normal situation, hematopoiesis in adults occurs in the bone marrow and lymphatic tissues.” (Medicinenet.com) More than 50% of cancer patients end up with anemia. This impacts their immune systems, their quality of life and their survival rates. Anemia can make the cells in our bodies not get enough oxygen. Sometimes, a lack of oxygen may be severe enough to threaten people’s life. Anemia can also cause our hearts to work harder. Severe anemia can cause a delay in cancer treatments or make the treatment dose be reduced. It can also cause some treatments to not work as well as they should. Cancer can cause anemia in many different ways. Normally, the kidneys send hormones to the bone marrow signal for it to produce red blood cells. This process can be disrupted by cancer slowing the hormone production or by not allowing the body to use stored iron. Red blood cells also wear out faster than normal in cancer patients and may not be replaced as quickly as they are needed. Fewer red blood cells means there is less hemoglobin carrying oxygen throughout your body and hence, the immune system and everything else gets compromised. This study showed, ” The addition of glucan to the food during cancer increased chemotaxis and adhesion of neutrophils, affected the production of myeloid growth factors resulting in increase of hematopoiesis and influenced peripheral progenitors cells in the blood. In a model of irradiated mice, glucan caused regeneration of hematopoiesis and increased survival. In addition, some studies showed a direct increase in the destruction of tumor cells and higher tumoricidal activity by glucan treatment.” (Vetvicka 2015) The study also looked at anemia and chronic fatigue syndrome.
Journal of Nature and Science 2015– This article reports on a study conducted on mice that had artificially induced Chronic Fatigue Syndrome (CFS). The study concluded that Beta Glucan improved the conditions of CFS.
This article evaluates the use of yeast-derived Beta Glucan on mice, who have experimentally induced Chronic Fatigue Syndrome (CFS). Chronic Fatigue Syndrome is often hard to diagnose, as fatigue is a factor in many infections and diseases. A standard means for diagnosis is that at least a 50% reduction in activity has been present for over 6 months. This has a huge impact on individual’s enjoyment and participation in their own lives. Treatments have been elusive. About 60% of patients with CFS also have immunological disturbances. Oxidative stress is being examined in the pathogenesis of this disease. In recent years, natural molecules have been examined for their effects on CFS. These include: dietary supplements, such as olive extract, Vitamin C and E and green tea extract; Curcumin; Ginseng and a Japanese herbal medicine with yeast extract. Due to some positive results from the herbal medicine (yeast-based), this study was generated to look into Beta Glucan’s effects. The study found that the NK cells in the spleen were increased; the production of important cytokines increased; there was a proliferation of lymphocytes; and the activities of 4 enzymes in the brain and blood were restored with the Beta Glucan. Conclusion: treatment with Beta Glucan may be an effective treatment for CFS.
Journal of Nutrition and Health Sciences 2015– Journal of Nutrition and Health Sciences-Vol.2, Issue 3- “Anti-Inflammatory Effects of β-Glucan in Cancer Related Fatigue”- This article reports on a study on fatigue in cancer patients and the effects of B-Glucan on the acute inflammatory responses.
This article examined fatigue and immune-mediated inflammatory diseases that are often associated with cancer treatments and stress. 100% of cancer patients report issues with fatigue and that fatigue continues in 50% of patients even a year after treatment. This study was a double blind trial with 58 patients with a control group and a group taking 200 mg of B-glucan- Glucan#300. The study measured concentrations of CRP, serum amyloid, orosomucoid and pre albumin, all indicators of inflammation. The results showed an overall improvement in the patients’ condition and a suppressed inflammatory manifestation.

Journal of Tumor 2016 — A randomized, double-blind, placebo-controlled trial compared β-glucan #300 and a placebo in people after complex surgical, radiation and/or chemotherapy treatment of cancer. Starting points of cancer disease are closely associated with obesity. The role of glucan in potentiation of immune system is well established, including effects on cancer development. In this study, we focused on effects of short term glucan supplementation in patients during complex cancer treatment. Our findings show the significant effects of glucan supplementation on induction of NK cell, suggesting that addition of glucan to the diet could be beneficial for prevention of cancer remission. The glucan-supplemented group exhibited some improvements in psychic conditions, nutritional state and overall feeling of well-being. Longer supplementation seems to be necessary.
International Journal of Clinical and Experimental Medical Sciences 2016 — Our previous work was devoted to the possibility of positively influencing some immune mechanisms in patients suffering from cancer related fatigue. The relation between cancer and fatigue is well established as well as the positive effects of glucan treatment in both experimental and clinical models of cancer. The aims of this study was to evaluate the hypothesis that glucan supplementation might influence the NK cells in patients with cancer-related fatique. This study clearly demonstrated the positive effects of short-term glucan supplementation on post-surgery and the rehabilitating phase of patients overcoming cancer disease.
Journal of Nutrition and Health Sciences 2016 — Curcumin is a turmeric-based compound with potential health benefits. In our study, we focused on the anti-inflammatory effects of curcumin. We directly compared the biological effects of five different types of curcumin, showing that only some of them have significant biological activity. We can conclude that despite the fact that curcumin truly represents a biologically active natural molecule; its activity differs widely based on the type of sample. Clearly, not all curcumins available were created equal.
International Clinical Pathology Journal 2016 — “Comparison of Immunological Effects of Commercially Available β-Glucans: Part III “- International Clinical Pathology Journal- Volume 2 Issue 4 2016 –
This research study is the third examination of 15 Beta Glucan products from different sources- mushrooms, barley, yeast and oat, that are available to the general public. The researchers looked again at Phagocytosis, nitrite oxide formation, IL-2 and IFN-γ formation, and added a lung cancer model. No clear relevance between the source used for isolation and biological effects was found. As before, the 15 individual glucans differed in biological effects based on tested characteristics, but Glucan #300 again served as a benchmark in all the trials. So, highly purified and highly active glucans have strong and pleiotropic effects, but poorly defined glucans have only medium (if any) biological effects. Important for consumers and physicians to know!
International Clinical Pathology Journal 2016 — “Comparison of Immunological Properties of Various Bioactive Combinations: Part II “- International Clinical Pathology Journal- Volume 2 Issue 5 2016 –

Methods: In this study we directly compared the effects of eleven different combinations on the immune reactions.
Results: We evaluated phagocytic activity, IL-2 and superoxide anion formation, NK cell activity, antibody response and breast cancer inhibition. Our results demonstrated strong differences among individual combinations.
Conclusion: In most cases, these combinations have no effects at all. The only consistently active mixture was RVB 300
PLOS ONE November 9 2016 — “Effect of 1,3-1,6 β-Glucan on Natural and Experimental Deformed Wing Virus Infection in Newly Emerged Honeybees (Apis mellifera ligustica)”, PLoS One (11), November 2016.
The loss of honeybee populations in the Western Hemisphere and the world will have devastating effects on agriculture, as they are key pollinators in many ecosystems. Deformed Wing Virus is one of the main contributors to the loss of honeybee colonies. This virus persists in the bee colony until the colony eventually collapses. A concomitant infection is often present with Varroa, a mite that supports the replication of the DWV to high titers, which suppresses the bees immune system. This study used Beta Glucan in several dosage sizes and in different populations of honeybees. The cohort groups were given the same treatments- no injection, injection of a high-copy number DWV suspension into the haemocel (experimental DWV infection) or injection of PBS into the haemocoel (physical injury). A group of control bees were fed a diet enriched with Beta Glucan and then they received the same treatments. The Beta Glucan group had significantly less bees infected and their viral loads were lessened. Their survival rates were significantly better. This suggests that Beta Glucan may contribute to an increase in honeybee resistance to infections from viruses.
Journal of Tumor December 2016 — Effect of β-glucan Supplementation on Levels of IgM, IgA, IgG and Its Subclasses IgG1, IgG2, IgG3, and IgG4 in Cancer Patients.
This is a continued evaluation of the role of Beta Glucan as a supplement to traditional cancer treatments. This study focused on humoral immunity and measured changes in IgM, IgG, and IgA levels- immunoglobulins. The study found that there was a significant decrease in IgG1 levels in the placebo group, which could affect their anti-infectious immunity especially for respiratory diseases, as abnormal IgG1 levels are often found in patients with respiratory problems and autoimmune diseases. Short term treatment with Beta Glucan stabilized the levels of IgG1, especially in women. This could result in maintaining immunities to infectious diseases that could occur during cancer treatments due to suppressed immune response.
Journal of Medicinal Food December 2016 — “Essential Oils from Thyme (Thymus Vulgaris): Chemical Composition and Biological Effects in Mouse Model”
The use of herbs in medicine is as old as history can record. Most of the data is anecdotal, and their biological and pharmacological activities have not been well researched. In this study, the authors undertook to evaluate the effect on immune response of the essential oil derived from the herb, Thyme. The authors compared the essential oil of Thyme from seven different companies and compositions. They looked at effects on phagocytosis, cytokine production, chemotaxis, edema inhibitions and liver protection. The results showed limited biological activity in immune response across all the samples. Their conclusion was that though there are benefits to herbal remedies, if one is looking for improved immune response, Beta Glucan would be a better option.
Annals of Translational Medicine 2016 —”Effects of curcumin on Helicobacter pylori infection”. Annals of Translational Medicine, Vol 4, No 24 December 2016, Vetvicka, V., Vetvickova, J., Fernandez-Botran, R.
This article examines the effect of different curcumin (turmeric) samples on the H. pylori bacterium, which is a Gram-negative bacteria that is linked to stomach and colorectal cancers, as well as peptic ulcers and gastritis. 50% of the world’s population is affected by this bacteria. Many studies have reported the positive effects of curcumin as an anti-inflammatory and anti tumor herbal agent. Past mouse studies have shown a significant inhibition in gastric inflammation, and so this study looked at 5 different samples of curcumin, and found there was a reduction in inflammation and bacteria and a formation of specific antibodies. This suggests that curcumin has strong immunostimulating properties. Of the 5 samples, Sample #1, Sabinsa, was the most active sample, and had the most impressive results.

Anticancer Research 2017 —Vetvicka, V. & Vetvickova. Fucoidans Stimulate Immune Reaction and Suppress Cancer growth. 37:6041-6046 (2017)
This article examined the efficacy of fucoidans, complex polysaccharides found predominantly in marine algae, echinoderms and seagrasses, as natural immunomodulators. The study used a variety of fucoidans, both purified samples and commercially available products containing fucoidans. Measures were taken on phagocytosis, mitogenic response, natural killer cell activity, antibody formation and inhibition of breast cancer formation. Results showed that fucoidans have significant biological activities, though the pure fucoidans seemed to have the most activity. The addition of other substances to fucoidans needs to be further studied to determine whether there is any positive effects.

This article looks at high cholesterol levels, hypercholesterolemia, as it is one of the primary risk factors in cardiovascular disease. Since obesity and sedentary lifestyles are more prevalent, creative ways to lower LDL-C (low density lipoprotein cholesterol) need to be explored. Dietary supplements may be a key to helping regulate cholesterol. Beta Glucans act as dietary fibers in the digestive tract. This, as well as their well-studied enhancement of the immune system, can provide support to both the immune and cardiovascular systems. Both the soluble and insoluble forms of B-Glucans have a role. The article looks at studies on Glucans, cholesterol and the effects of a fiber rich diet.

This article is a continuation of research on different available Beta Glucans and cancer. Research on the efficacy of Beta Glucan is extensive and may be leading to it becoming a licensed drug in this country. It has stood the test of time, and more and more uses are being identified because of its immunomodulatory properties. More studies to identify the most active Beta Glucans are essential to help consumers. Sixteen different commercial glucans were tested on phagocytosis of peripheral blood neutrophils, inhibition of cancer growth, and as an adjuvant using an experimental model of ovalbumin. These researchers compared these 16 new samples, which included Glucan #300 again, as it had been shown to be the most biologically active sample they had tested in the past tests of 43 samples. In all of the tests this time, and in the past, Glucan #300 was the most active.

This article looks at the effects of Beta Glucan and Vitamin D supplementation on Diabetic Retinopathy. Diabetes is a serious, lifelong disease that increases the blood glucose levels in individuals affected by it. It impacts circulation, organs, including eyes, blood pressure and overall health. Many people with diabetes are overweight and may lose limbs and/or their eyesight, as the disease progresses. This study focused on the levels of Vitamin D, nutrition and metabolism of cholesterols and triglycerides. 500 mg of Glucan #300 was used, along with Vitamin D3, which was based on age and weight. Their results showed that there was a significant increase in vitamin D levels, an improvement in HDL levels (the good cholesterol) , and a strong decrease of the total level of cholesterol. This further supports the research that Beta Glucan and Vitamin D can have a positive effect on health.

Diabetes is a prevalent disease in the USA and the world. Almost 10% of Americans have or will have diabetes. Of those, 5% will get diabetic retinopathy, making it the most common cause of vision loss among people with diabetes and the leading cause of vision impairment and blindness among working-age adults. It is caused by damage to the blood vessels in the retina from several sources including poorly controlled blood sugar and inflammation. This study examined the effects of dosing with either Vitamin D plus beta glucan, Vitamin D alone, or Vitamin D and a placebo on 52 patients over a 3 month period. The results continue to support that supplementation with a combination of bioactive molecules (Vitamin D and Beta Glucan) might positively influence the health of individuals with diabetes and other diseases. Leptin levels and C-reactive proteins both were lowered in the Vitamin D and Beta Glucan group. Decreased leptin levels may help to therapeutically influence diabetes. Vitamin D levels increased in all groups, though they were still at a deficit. This suggests that a longer study may need to be initiated.

This study looks at the combination of Beta Glucan with another bioactive molecule, Coenzyme Q10 (CoQ10), to determine if there are significant synergistic effects of their interaction. Beta Glucan continues to be the most studied immunomodulator, and it has been determined that it can be successfully combined with a number of other bioactive molecules (Vitamin C, selenium & Resveratrol) to create even better immune responses. CoQ10 acts as an antioxidant, which protects cells from damage and plays an important part in the metabolism.
The study was done on mice, and there were 4 groups- a control group, a group with CoQ10 alone, a group with Beta Glucan alone, and a group with the combination. The effects were measured through evaluation of phagocytosis and cytokine secretions.
The Glucan-CoQ10 combination had stronger effects on lowering nitric production and total number of leukocytes, than any other group. The study concluded, “There is significant synergy between coenzyme Q10 and β-glucan.”

Diabetes is a prevalent disease in the USA and the world. Almost 10% of Americans have or will have diabetes. Of those, 5% will get diabetic retinopathy, making it the most common cause of vision loss among people with diabetes and the leading cause of vision impairment and blindness among working-age adults. It is caused by damage to the blood vessels in the retina from several sources including poorly controlled blood sugar and inflammation.
This is a study to further examine the effects of Vitamin D and Beta Glucan supplementation on leptin levels, proteins and the overall health of people with diabetic retinopathy. The patients were put into 4 groups and studied for 3 months – Group A was supplemented with Vitamin D and Beta Glucan; Group B was supplemented with Vitamin D and a placebo; Group C was supplemented with just Vitamin D; and Group D was a healthy group of patients, who got no supplementation. Group A (Beta Glucan and Vitamin D) had a lower level of leptin and interestingly, more weight loss. This group also showed a positive change in their apolipoprotein A1 metabolism. This protein binds lipids (oil-soluble substances such as fat and cholesterol) to form lipoproteins. They then transport the lipids through the lymphatic and circulatory systems, which could help with overall health and weight loss. More support for Beta Glucan being combined with other supplements!

IgG4-Related orbital disease in patients with diabetic retinopathy: Effects of Glucan and Vitamin D Supplementation.” Pathology Discovery, vol. 5, no. 1, 2018, p. 1., doi:10.7243/2052-7896-6-1.
This article again looks at the impact of Beta Glucan when used in conjunction with Vitamin D supplementation on patients identified with Diabetic Retinopathy and Macular Edema, and particularly 7 individuals within that group , who had high levels of IgG4. IgG4 is a subclass of IgG4, which is the most common form of immunoglobulin, which are antibody proteins that are found throughout the body. All 7 individuals were identified through this study to have a probable diagnosis of IgG4ROD (related ophthalmic disease), which involves inflammation, lesions and infiltrates. All the individuals had very low levels of Vitamin D.
The individuals were administered Vitamin D and Transfer Point Beta Glucan over the course of three months. The study reviewed cited past studies with Vitamin D and Beta Glucan, and came to some strong conclusions: Vitamin D is important to mediate the risk of insulin resistance by its effects on insulin receptors; AND “ Functional food supplemented with glucan represents an important perspective not only for treatment, but also for prevention of diabetes mellitus and additional diseases, and possibly leading to reduce(d) healthcare costs and disease prevalence.” They identified that Glucans have a long history in reducing diabetes and insulitis.
Diabetic Retinopathy is the fifth most common preventable cause of serious vision damage and blindness.

This article is an intensive review of research on Beta Glucan to determine when it will move from a food supplement to a widely accepted, effective drug. The positive effects of foods as immunomodulators is being explored daily. Although there are many substances, ie. curcumin, garlic, ginseng, etc, that are popular as supplements, only Beta Glucan has over 20,000 published studies about its immunomodulating properties. In Japan, Beta Glucan is already a licensed drug. In America it continues to be a food supplement. The article includes many of the uses and the most recent research to support the use of Beta Glucan. It supports the idea that it should become a drug, because it has a clearly defined origin and structure, a recognized MOA (mechanism of action), and a low risk of side effects, as well as being effective in improving immune responses to a variety of diseases.

This article is a brief review of the current uses of Beta Glucan for immune supplementation for cancers, its effects on lowering cholesterol, its hypoglycemic effects, and its ability to support treatments of many communicable and non-communicable diseases. The authors present studies that show Beta Glucan’s positive effects on many biological reactions, and they suggest that it could be useful in many more situations where improved immune reaction is desirable.

This study took a group of marathon runners, 132 in the group given a dairy drink with Beta Glucan in it for 45 days before a marathon and 45 days after the marathon and 225 runners in the control group, who were given a macro-nutrient and calorie matched drink for the same time period. The researchers then measured the effects on URTI (upper respiratory tract infections). There was no difference in the groups on the duration or number of URTI episodes, but the group using Beta Glucan had decreased symptomatic days, and less severe symptoms, and missed fewer workout days after the marathon. The authors concluded,”…..dispersible yeast Beta Glucan, incorporated into a food matrix, confers beneficial effects on exercise-induced URTI in marathon runners.”
