Shiitake Extract
Lentinula edodes — the most widely recognised mushroom in our range, standardised for polysaccharide content, supplied for immune-support formulations.
The one mushroom on this list you've probably already eaten.
Shiitake is by far the most widely recognised mushroom in our range — sold fresh and dried in ordinary grocery stores worldwide and eaten as a culinary staple across many cuisines, unlike the more specialist functional mushrooms elsewhere in our catalogue. That familiarity matters for safety questions too: if you search for Shiitake safety information, you'll likely come across "shiitake dermatitis," a genuine but specifically whole-raw-mushroom reaction — not relevant to the standardised extract supplied here. See Safety & Risk Information below for the full detail.
We supply standardised to 10–20% polysaccharides. Every batch carries a certificate of analysis confirming this by HPLC. See Quality Assurance for the full testing process.
Where this extract typically gets used.
Immune-support formulas
The primary use case — commonly formulated alongside other medicinal mushrooms in general immune-resilience stacks.
Recognisable-name positioning
Its widespread culinary familiarity gives it a genuine consumer-trust advantage on a label compared to less familiar functional mushroom names.

Where it comes from, and how we hold that to a standard.
Trade buyers increasingly need to answer sourcing questions themselves — here's what we can tell you about this specific ingredient.
GMP-certified processing
Grown and processed at a GMP-certified facility in China, audited on our own schedule rather than taken on trust from a spec sheet — see Quality Assurance.
Fruiting-body verified
Every batch is verified as fruiting-body material, not the cheaper mycelium-on-grain biomass sometimes used to bulk out lower-grade Shiitake products.
Long-term supplier relationships
We work with established processing partners on an ongoing basis rather than opportunistic spot-buying, which supports both batch-to-batch consistency and supply continuity.
Batch traceability
Every batch is traceable back to its processing facility and production run — ask if you need this documented for your own supply-chain due diligence.

Shiitake, answered.
It's a genuine culinary staple sold in ordinary grocery stores worldwide, unlike the more specialist functional mushrooms elsewhere in our range such as Reishi or Cordyceps, which most consumers wouldn't recognise as a food item.
It's a documented skin reaction that some people experience after eating raw or undercooked whole shiitake mushrooms. It's specific to that whole-food context and isn't relevant to a standardised powder extract like the one supplied here — worth knowing if you come across the term researching this ingredient.
By HPLC, per batch, with the certificate of analysis showing the tested polysaccharide percentage for the specific batch you're buying.
It follows the standard Starter tier from 1–10kg/month — see Wholesale & Trade Accounts for the full tier structure.
It's generally well tolerated with no significant common interactions identified — see the Safety & Risk Information above. This isn't medical advice; consumer-facing products should still carry appropriate guidance.
