Fungi Perfecti® is a family-owned, environmentally friendly company specializing in using gourmet and functional food mushrooms to improve the health of the
planet and its people. Founded by mycologist and author Paul Stamets, they are leaders in a new wave of technologies harnessing the inherent power of mushrooms and
fungal mycelium worldwide. Fungi Perfecti is Certified Organic by the Washington State Dept. of Agriculture as both a mushroom producer and processor. In business since 1980, they offer an ever-expanding family of Host Defense® Organic Mushrooms™ supplements, for Supporting Natural Immunity.*

Host Defense® mushroom capsules are made with Certified Organic, freeze-dried, non-GMO mushroom mycelium/fruitbodies, encased in a plant-based capsule made from pullulan. Pullulan, a non-GMO, naturally-fermented polysaccharide polymer, is starch-free, gluten-free, and preservative-free. Pullulan capsules are known for their high-oxygen impermeability which is particularly advantageous to the encapsulation of product that may be sensitive to oxidation.
