Step into an autumn woodland where rain has softened a fallen hardwood log, and a fan-shaped cluster of oyster mushrooms is quietly working a marvel most people never see. Beneath the visible caps, a network of white mycelium threads is digesting the wood itself — secreting enzymes that break tough cellulose, hemicellulose, lignin, and pectin into simple sugars the fungus can feed on. This is saprophytic life in action, and it is exactly the chemistry we set out to capture. From organically cultivated fruiting bodies, we use nothing but hot water to draw out the mushroom’s natural fungal polysaccharides — including beta-glucan — then spray-dry the liquor into a standardized powder carrying 10% to 30% polysaccharides. The fruiting body it came from is famously nutrient-dense, holding roughly 20-23 grams of protein per 100 grams alongside a wide amino acid profile and abundant minerals. In traditional dietetics it has long been described as warm in nature and sweet in taste. What reaches your formula is a fine brown to light-yellow, food-grade powder — the forest’s quiet chemistry, concentrated into a single clean ingredient for nutraceutical, functional food, cosmetic, and animal nutrition applications.

Every batch is measured against a declared total polysaccharide range of 10% to 30% using the phenol-sulfuric acid method with UV-Vis detection. That means a consistent, quantifiable specification for dosage design — batch after batch, from the first drum to the last.
The raw oyster mushroom naturally carries about 20-23 grams of protein per 100 grams, along with a broad spectrum of amino acids and abundant minerals. This nutrient density carries into the extract, supporting its role as a functional nutrient contributor in food and supplement systems.
Hot water alone draws out the water-soluble polysaccharide fraction — no organic solvents, no chemical processing aids anywhere in the chain. The result is a genuinely clean ingredient you can explain to customers in one sentence: mushroom plus water.
Beta-glucan and fungal polysaccharides are structural compounds native to the oyster mushroom fruiting body, carried intact through water extraction. These naturally occurring constituents are what give the extract its recognized value in immune-support nutraceutical formulation work.
