Mode of Action – The Science Behind Nutramunity

Exploring the unique structure and proven function of yeast beta-glucan. ( undirtitill)
Nutramunity™ Beta-Glucan works by engaging the immune system’s frontline defenders. After ingestion, it reaches immune cells in the gut where macrophages and dendritic cells recognize its unique β-(1,3/1,6) structure.
This binding “primes” these cells—making them more alert, more active, and quicker to respond. This activation triggers a cascade that boosts phagocytosis, enhances cytokine signaling, and strengthens antibody responses.
The result: a faster, stronger, and more coordinated immune defense.

The Structural and Functional Advantage

Structural Integrity - Superior Immune Activation
Nutramunity™ Beta-Glucan has a highly branched β-(1,3/1,6) structure that fits immune receptors like a key in a lock—ensuring stronger binding to Dectin-1 and more powerful immune activation.
Insoluble, High Molecular Weight - Maximum Bioactivity
Its insoluble, high-molecular-weight particulate form forms a “phagocytic synapse” with macrophages, triggering robust phagocytosis, cytokine release, and rapid frontline immune responses.
Proprietary Solvent-Free Process - Preserved Bio-Power
A unique solvent-free purification process preserves the glucan’s native structure, giving it superior functionality and stability compared to solvent-damaged or soluble beta-glucans.

Why Nutramunity Beta-Glucan from Yeast Outperforms Other Beta-Glucans

Yeast beta-glucan is more effective for immune support because it has a unique 1,3/1,6-branched structure that the immune system naturally recognizes and responds to.
Oat and barley beta-glucans are mostly linear fibers used for cholesterol and gut health, but they are not recognized by immune cells and therefore do not activate immunity.
Mushroom beta-glucans can support immunity but their branches are much shorter, making them less potent and less consistent than yeast.
Algal beta-glucans are mostly linear and low in molecular weight, which results in weak immune activation and limited scientific support.
Overall, yeast beta-glucan has the ideal structure and size for strong, reliable immune effects, unlike the other types.

Independent Research Confirms Superior Efficacy

Professor Václav Větvička is a world-renowned expert in β-glucan research, with decades of groundbreaking work in immunology and over 200 scientific publications. He is widely regarded as a leading authority in the field. We are proud to have Professor Větvička conducting research with us—his involvement brings unmatched credibility and scientific depth to our project.
Vaclav Vetvicka’s comparative immune-function studies demonstrated that Nutramunity™ Beta-Glucan consistently outperformed competitor beta-glucans by achieving the strongest increases in phagocytosis, IL-2 cytokine production, and antibody formation, confirming its superior immune-activating efficacy.
Phagocytic activity refers to the ability of specialized cells, known as phagocytes, to ingest and sometimes digest foreign particles, including pathogenic bacteria. These immune cells – such as macrophages, neutrophils, and monocytes – play a crucial role in our body’s defence against infections.
Yeast beta-glucans are known for their immunomodulatory properties. When beta-glucans bind to specific receptors on phagocytes, they promote phagocytosis and the release of cytokines. This activation results in a cascade in the immune response, making beta-glucans essential contributors to our body’s defence mechanisms.
