| Extract category | Selection priority |
|---|---|
| Lion’s mane — Hericium erinaceus | Distinguish fruiting-body and mycelial sources before comparing constituent claims. |
| Reishi — Ganoderma species | Name the species and decide whether a triterpenoid specification is required. |
| Cordyceps | Specify the exact species and cultivated material; common names alone are insufficient. |
| Chaga — Inonotus obliquus | Establish harvested material and origin rather than assuming a fruiting-body source. |
| Shiitake — Lentinula edodes | Separate the requested glucan specification from a general polysaccharide declaration. |
| Turkey tail — Trametes versicolor | Identify the species, source, and composition of the particular extract grade. |
| Maitake — Grifola frondosa | Match the declared composition and physical properties to the intended formulation. |




| Source | Essential disclosure |
|---|---|
| Fruiting body | Identified species and harvested tissue. |
| Mycelium | Cultivation method, harvested biomass, and substrate separation. |
| Myceliated grain | Grain identity and inclusion of substrate in the processed material. |
| Method | Typical purpose | What determines suitability |
|---|---|---|
| Hot water | Recovery of water-extractable fractions, including some polysaccharides. | Conditions used and measured final composition. |
| Alcohol | Recovery of less polar constituents, including certain reishi triterpenoids. | Solvent choice, target constituents, and residual-solvent results. |
| Dual extraction | Combining fractions obtained through different solvent steps. | Process sequence, fractions retained, and final assay. |


| Parameter | What the specification should establish |
|---|---|
| Identity and process | Scientific name, source material, and extraction solvent. |
| Composition | Distinct β-glucan, alpha-glucan, total polysaccharide, and relevant marker results. |
| Analytical basis | Method, units, and dry-basis or as-is reporting. |
| Extract ratio | Starting-material basis and whether the ratio describes native extract or the carrier-containing preparation. |
| Added ingredients | Carrier identity, proportion, and other excipients. |
| Physical properties | Appearance, moisture, particle size, density, and relevant solubility or dispersibility conditions. |
| Format | Practical formulation questions |
|---|---|
| Capsules and tablets | Does the powder meet flow, fill-weight, and compression requirements? |
| Sachets and blends | Does it mix uniformly and resist segregation or moisture uptake? |
| Beverages | Does it dissolve or disperse, and how does it affect sediment, taste, color, and stability? |
| Gummies | Can the target inclusion level be accommodated within processing and sensory limits? |


| Decision | Information to establish |
|---|---|
| Select a grade | Species, source, target composition, format, and application. |
| Qualify the material | Specifications, documentation, sample terms, and acceptance criteria. |
| Plan the purchase | Quantity, packaging, destination, lead time, and quotation terms. |

Yes. Start with the species, finished-product format, destination market, and estimated quantity. Identify which requirements remain open, such as composition or carrier restrictions, so the inquiry distinguishes exploratory sourcing from a purchase-ready specification.
Not necessarily. Methods can differ in sample preparation, specificity, and recovery. Request the method references and reporting bases, then have the results assessed for comparability before treating one percentage as higher or lower quality.
Record the sample’s grade, lot number, specification, and COA. Establish whether it represents current production, then agree acceptance criteria and change-notification requirements for commercial orders. Sample approval alone should not replace incoming-batch verification.
Provide the species, required proportions, source preferences, and whether analytical targets apply to each component or the finished blend. Clarify whether you are sourcing separate ingredients or a premixed material, since quotation and documentation requirements differ.
Send the ingredient identity, target specification, application, quantity, delivery destination, packaging needs, and required documents. Include any carrier restrictions or preferred process so the quotation can address a clearly defined grade and purchasing requirement.
