Why Choose a Hot-Water Extract? Rigid mushroom cell walls contain a compound called chitin, the same compound found in the hard outer shells of lobsters, crabs, and other shellfish. This compound is indigestible and remains intact throughout the gastrointestinal tract. Only hot-water extraction gently dissolves chitin while releasing therapeutic compounds such as beta-glucans and polysaccharides. This permits identification and concentration, to deliver a standardized extract in a therapeutic dose. Unless there is a label claim validated by an ISO 17025–accredited laboratory, you are likely getting a simple mushroom powder, a disappointing return on your investment. All New Roots Herbal medicinal mushroom products are rigorously tested in our ISO 17025–accredited laboratory, the highest global standard for supplement testing, ensuring precise quantification of therapeutic compounds and stringent screening for heavy metals, herbicides, pesticides, and microbiological contamination.
