Organically certified 10:1 concentrated extract for fruiting bodies only; same-day shipping
G. frondosa maitake mushroom extract powder is pharmaceutical-grade and is sold by Earth Made Nutritions Inc. to companies across North America that make dietary supplements, useful foods, and cosmetics.
What's different about our extract: Using both water and ethanol to extract mushrooms gives 30–40% polysaccharides with confirmed beta-glucan content, while raw mushroom powder only has 1–3%. Every batch comes with approval from a third-party lab.

Chitin makes up 80–90% of standard mushroom powders, which can't be digested. Our two-step process breaks down cell walls and concentrates polysaccharides to 30–40% by weight, which means that each dose has 10–15 times more bioactive content.
Technical benefit: Enzymatic pre-treatment frees bound beta-glucans with (1→3)(1→6) branching patterns, which is the exact structure that has been studied in clinical study.
The main problem with mushroom extracts is that the raw materials aren't always the same. This is solved by:
Spectrophotometric testing on each batch of production
Analysis Certificate with real test results, not just "conforms"
Samples that will be kept for 36 months to check the quality
Megazyme is an enzyme-based assay for measuring the amount of beta-glucan (not guessing).
Polysaccharides make up 32.4% of the COA data, while Beta-Glucans make up 21.8% (Batch #ME2024-03).

Q: How does your extract compare to mycelium-based products?
A: Only fruiting body is used. Mycelium products commonly contain rice or oats, which diminish bioactive value. Our HPTLC test shows pureGrifola frondosa without grain fillers.
Q: Can I see test results before ordering?
A: Yes. Get a recent batch COA. We present measurable data, not "pass/fail" outcomes.
Q: Why are 10:1 extract and 30% polysaccharide specifications different?
A: A 10:1 concentration ratio (10kg mushroom → 1kg extract). 30% polysaccharides demonstrate bioactivity. We provide both since ratio doesn't ensure potency.
Q: Does EU/Canada accept your organic certification?
A: Equivalency agreements recognise our USDA Organic certification. We supply NOP-EU equivalency documents for EU. Canada: COR-certified upon request.
Q: Do you customise extraction ratios or specs?
A: For orders over 500kg. Our R&D team can tailor extraction settings to polysaccharide profiles or beta-glucan ratios.
Q: How's your contamination testing?
A: The EPA tested every batch for 230+ pesticides, heavy metals (USP limits), and microbiological contamination. No batch has failed in 8+ years.
Q: Could you give stability statistics for my formulation?
A: Standard stability studies (24 months, ICH) are available. Our lab partners offer custom compatibility testing (fee).
Q: If I require less than 25kg?
A: Aluminium bags in lesser quantities are available. Note: Higher per-kg pricing for quantities <25kg.
