What are beta-glucans and how do they support immune health?

Beta-glucans are naturally occurring polysaccharides (complex carbohydrates) found in the cell walls of yeast, mushrooms, oats, and barley. They are one of the most extensively researched natural immune-modulating compounds, with hundreds of published studies demonstrating their ability to support healthy immune function. NOW’s Beta-Glucan is derived from the cell wall of Saccharomyces cerevisiae (baker’s yeast) and is specifically structured as a 1,3/1,6 linkage — the configuration shown in research to be most effective at interacting with immune cells. Beta-glucans work primarily through the gut-associated lymphoid tissue (GALT) — a specialised immune tissue that lines the intestinal tract and plays a crucial role in the body’s overall immune response. When beta-glucans reach the GALT, they interact with specific immune receptors (including Dectin-1 and complement receptor 3) on macrophages, natural killer (NK) cells, neutrophils, and dendritic cells — helping to prime and activate these cells for a more effective immune response. Importantly, beta-glucans are immune modulators rather than immune stimulators — they help the immune system respond more effectively without overstimulating it. This formula is complemented by 160mg of Maitake mushroom powder (Grifola frondosa) — a medicinal mushroom also rich in beta-glucans and well-regarded for its own immune-supporting and adaptogenic properties.

⚠️ Autoimmune caution

Because beta-glucans modulate immune activity, those with autoimmune conditions (such as rheumatoid arthritis, lupus, multiple sclerosis, or inflammatory bowel disease) or those taking immunosuppressant medications should consult their healthcare practitioner before use. Beta-glucans may not be appropriate for those whose immune systems are already overactive.
