Beta Glucan for Boosting the Immune System


The immune system is the most important aspect in fighting cancer. Knowing what your immune system does and why it is so important in the fight against cancer is the first step to healing your body from in the inside out.

The immune system is made up of cells, tissues, proteins, chemicals and organs that work together to defend us against infectious organisms and other invaders. The white blood cells that make up the immune system are made in the bone marrow. These cells move through blood & tissue. Every time a microbe or germ is conquered, the immune system remembers it. If the body comes into contact with that microbe again, it will be defeated quickly.

The proteins of the immune system are called antibodies that can help neutralize infection or toxins that some germs produce. In most cases, our immune system does a great job of keeping us healthy and preventing infections, but sometimes problems with the immune system can lead to illness and infection such as autoimmune diseases, inflammatory responses and in worst cases, cancer.  

Approximately 70 – 80% of your immune tissue is located within your digestive system. The health of your gut bacteria and the health of your immune system are vitally linked. When your gut bacteria is balanced, your immune system is also balanced. 

Now that you understand how critical the immune system is you may be wondering, what went wrong with my immune system and how can I help it? Well, not every type of cancer is caused by a unhealthy immune system, but that doesn't mean that you can't help your immune system be the best it can be. If you are going through cancer treatments or suffering from autoimmune conditions, you are probably filling your body with toxins to try and kill all of the bad cells, but those toxins are killing off all of the good cells too. A supplement that  has come to the forefront recently to help aide the immune system during treatment is β-Glucan. 

Technically beta glucan is an immunomodulator which helps make your immune system smarter. It can help raise your immune system’s response so your body can naturally fight off and kill cancer. Beta glucan modulates or activates, but never over stimulates, which is key to its safety. In addition, glucan is one of the few natural immunomodulators for which we know not only the composition but also the mechanism of action. Medical doctors are finding and proving that it has many benefits, not only in helping the immune system, but also in combination with certain drugs.

First use of beta glucan as an immunostimulant for human cancer therapy was Brown Cancer researchers, led by Dr. Gordon Ross.  He discovered that beta-glucan can enhance the immune response in mice with injected tumors. This treatment is now being tested for the first time in humans at the University of Louisville and Memorial Sloan-Kettering Cancer Center in New York which is where Kellen is treated and is also a part of this study. I have listed below the studies that have taken place with beta glucan.
