Beta 1,3 1,6 D Glucan, 100 mg, 90 Veg Capsules, NOW Foods

NOW Foods Beta-1,3/1,6-D-Glucan delivers 100 mg of yeast-derived beta-glucan from Saccharomyces cerevisiae plus 160 mg of Maitake mushroom powder per capsule — a well-researched immune-modulating combination that works through the gut-associated lymphoid tissue (GALT) to support healthy, balanced immune cell activity.

Why

Beta-glucans are naturally occurring polysaccharides found in the cell walls of yeast, mushrooms, oats, and barley — and they are among the most extensively researched natural immune-modulating compounds available. NOW’s beta-glucan is derived from Saccharomyces cerevisiae (baker’s yeast) and 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), interacting with immune receptors on macrophages, natural killer (NK) cells, neutrophils, and dendritic cells to help prime and activate a more effective immune response. Importantly, beta-glucans are immune modulators rather than immune stimulators — supporting a balanced response without overstimulating the immune system. This formula is complemented by 160 mg of Maitake mushroom powder (Grifola frondosa), a medicinal mushroom also rich in beta-glucans and well-regarded for its immune-supporting and adaptogenic properties. Non-GMO, vegan, kosher, and GMP quality assured by NOW Foods — family-owned since 1968.

Formula Highlights

• Beta-1,3/1,6-D-Glucan (from Saccharomyces cerevisiae) — 100 mg: Yeast-derived beta-glucan in the 1,3/1,6 linkage configuration. Interacts with GALT immune receptors (Dectin-1, complement receptor 3) to support macrophage, NK cell, neutrophil, and dendritic cell activity. Immune modulator — not a stimulant.
• Maitake Mushroom Powder (Grifola frondosa) — 160 mg: Medicinal mushroom naturally rich in beta-glucans. Well-regarded for complementary immune-supporting and adaptogenic properties.
