Organic Grifola frondosa Fruiting Body Extract — 4:1
Organic maitake fruiting body extract at a 4:1 ratio. Maitake is bought largely on beta-glucan interest, so the ratio grade is offered alongside a note that a beta-glucan standardised grade can be quoted once the buyer’s method is fixed — beta-glucan results vary widely between assay kits.

Buyer Decision Guide
Maitake offers are hard to compare because beta-glucan figures depend on the kit used. Three points make two offers comparable.
- Extract ratio 4:1 by TLC on fruiting body input.
- Beta-glucan standardised grades quotable once the buyer’s assay method is named.
- Identity confirmed as Grifola frondosa fruiting body.
- Organic certificate and lot transaction certificate supplied with the shipment.
- Moisture, ash, heavy metals and microbiology reported per batch.
- COA, specification sheet and safety data sheet accompany each shipment.
How This Grade Differs
The conventional 4:1 maitake extract is listed separately. The ratio and method are identical here; the organic input is the only change, and it is the only change that affects the certification file.
Quality and Documentation
Ratio is declared on fruiting body input with the extraction batch recorded. Moisture, ash, heavy metals and microbiology are reported per lot, with organic certificates filed against the batch.
Regulatory Note
Organic grade: the material is sourced from certified organic growers and processors. The organic certificate and the lot transaction certificate are provided with each shipment on request. The certifying body and the standard applied differ by origin lot, so confirm the standard your market requires (for example NUS/NOP-type, EU 2018/848 or China Organic) before ordering. Certification is held by the producing operation and travels with the lot.
