Beta Glucans: Where molds help us fight bacterial infections, help wounds heal and helps us recover!

Molds survive by creating chemicals called beta glucans. These protect the mold from being eaten by bacteria. These same chemicals can help protect us from infection, in exactly the same manner. Think about the history of Penicillin, a mold derivative.

Beta-glucans are a type of polysaccharide found in the cell walls of certain fungi, yeast, bacteria, and grains like oats and barley. They have gained attention for their potential health benefits, including their ability to modulate the immune system and potentially help with infections. Here's how beta-glucans may be relevant to infection:

Immune system modulation: Beta-glucans are known as immunomodulators. They can activate various immune cells, such as macrophages, neutrophils, and natural killer (NK) cells, which play essential roles in the body's defense against infections. By enhancing the activity of these immune cells, beta-glucans may help the body respond more effectively to pathogens. Beta Glucans derived from mold helps fight infections!

Antimicrobial properties: Some studies suggest that beta-glucans may have direct antimicrobial effects against certain pathogens, including bacteria and fungi. They can inhibit the growth of these microorganisms, making it harder for them to cause infections.

Best use of Beta Glucans may be in the treatment of viral upper respiratory tract infection, including the common cold and influenza. Remember, COVID is a 'common cold virus.'

Respiratory infections: Beta-glucans have been studied in the context of respiratory infections, such as the common cold and influenza

a. Some research suggests that beta-glucan supplementation may reduce the incidence and severity of respiratory infections, potentially by enhancing the immune response in the respiratory tract.

Wound Healing may be improved with beta glucans derived from Mold!

Wound healing: Beta-glucans may also have a role in wound healing by promoting tissue repair and reducing the risk of infection in wounds.

It's important to note that while beta-glucans have shown promise in some studies, their effectiveness can vary depending on factors such as the specific source of the beta-glucans, the dosage, and the type of infection. Additionally, beta-glucans are typically considered as part of a broader approach to supporting immune health and infection prevention, rather than as a standalone treatment.


If you are considering using beta-glucans to support your immune system or for infection prevention, it's often advisable to consult with a healthcare professional. They can provide guidance on the appropriate dosage, potential interactions with medications, and whether beta-glucans are a suitable option for your specific health needs.
