Toxicity, Cautions, Contradictions

Agaricus blazei polysaccharides are considered to be safe and non-toxic. However, immuno-modulating substances should be avoided completely in organ transplant patients or people utilizing immuno-suppressive agents.

Clinical Research

The in vitro research and animal studies both show significant immune supporting properties.* A 2004 study found that hot water extracts of Agaricus blazei boosted NK cell activity.*

Active Constituents

Polysaccharides (1-6 linked proteoglycans  extracted from the cell walls).

Extraction Information

Research has been done on water-soluble and fractions of the polysaccharides isolated through a hot-water or hot-water/alcohol extraction process. As with the other medicinal mushrooms, the active compounds in Agaricus blazei, the polysaccharides, are internal structural components of the indigestible cell walls. Extraction with a heated aqueous solution is required to release these active compounds into a bioavailable form. Our product is a hot-water/alcohol extract, ensuring the presence of both the water and alcohol-soluble compounds. Our 45% polysaccharide extract is the only hot-water-extracted, guaranteed potency form of Agaricus blazei now being sold in North America.
