What we test, every single lot
Before any batch is sold, it's tested by an independent, accredited lab. Nothing ships without a passing Certificate of Analysis (COA) on file.
| Test | What it confirms |
|---|---|
| Beta-glucan (Megazyme) | Real, active mushroom content — not grain starch |
| Identity | The species on the label is the species in the tin |
| Heavy metals | Lead, arsenic, cadmium, mercury within safe limits (mushrooms bioaccumulate — this matters) |
| Microbials | Yeast, mold, and pathogen screening |
Made in a cGMP-compliant, allergen-controlled facility (21 CFR Part 111), with certified-organic ingredients.
Fruiting body vs. "mycelium on grain"
This is the fault line in the whole category — and where most brands quietly cut cost.
Fruiting body (what we use)
The actual mushroom. Beta-glucans concentrate here. Testable, and we publish the number.
Mycelium on grain
Mushroom roots grown on rice or oats, then milled with the grain. Cheap, and often mostly starch — with far less beta-glucan than the label implies.
The tell is on the panel: a product that reports "total polysaccharides" instead of beta-glucans may be counting grain starch. We report beta-glucans, measured by the Megazyme assay, and we test alpha-glucan (starch) too — so there's nowhere to hide.
How to read a Certificate of Analysis
- Find the beta-glucan %. This is the active number. Higher and disclosed is good; "total polysaccharides" alone is a yellow flag.
- Check the alpha-glucan (starch) %. High starch on a "mushroom extract" suggests grain filler.
- Confirm the lot number matches your tin. A COA is only meaningful for the batch you actually have.
- Scan heavy metals & microbials. They should be tested and within limits.

Testing FAQ
What is beta-glucan and why does it matter?
Beta-glucans are the active compounds concentrated in a mushroom's fruiting body. Measuring beta-glucan — not "total polysaccharides" — is the honest way to confirm you're getting real mushroom, not grain starch.
Who runs the tests?
Independent, accredited third-party labs — not us. Every released lot has a passing COA on file, and you can read it yourself.
Are these medical claims?
No. We describe testing and ingredient content, and we make only structure/function statements (like "supports focus") — no medical or disease claims of any kind.
