Every batch
Test results
Every batch is tested before it ships. The certificates are on this page.
The LOT number is printed on the back of the pack, next to the best before date. Or scan the code on the pack.
Most brands publish one certificate and leave you to work out how old it is. We publish one for every batch, with the method next to every number and the name of whoever ran the test.
Everything extracted on our farm in Flevoland is tested there, batch by batch, in our own lab. Not every raw material starts there: Chaga grows on birch in Finland, and ashwagandha root comes from India. Neither grows in the Netherlands. Shilajit is the one product we do not make at all, so Eurofins tests every batch of it, every test, at the source.
Who tests what
Where a product comes from decides how it is tested.
What we extract ourselves, we test ourselves, batch by batch, and an independent laboratory audits that work. Shilajit is different. It is a resin collected at 4,000 metres in the Himalayas and bought finished, so it goes to Eurofins in full, every batch, before it ships to us.
| Product | Where it comes from | Every batch | Independent laboratory |
|---|---|---|---|
| Lion's Mane, Reishi, Cordyceps, Focus Spray | Grown and extracted on our farm, Flevoland | Full release panel, our own lab | Eurofins, in line with our audited food safety plan |
| Chaga | Wild harvested from birch in Finland, extracted on our farm | Full release panel, our own lab | Eurofins, in line with our audited food safety plan |
| Mushroom Essentials Complex | Three grown on our farm, Chaga wild harvested in Finland, all four extracted on our farm | Full release panel, our own lab | Eurofins, in line with our audited food safety plan |
| Shilajit | Wild harvested resin, 4,000 m up in the Himalayas, India | Every test, by Eurofins, at the source | Eurofins is the laboratory for every batch |
| Ashwagandha KSM-66 | Root from India, extracted and capsuled on our farm | Full release panel, our own lab | Eurofins, in line with our audited food safety plan |
Our own lab is Fungal Development Europe, the company we run the farm through. Every certificate says so, so you always know who measured what. Eurofins has no connection to us.
Results by product
Each product keeps its own page: the current batch at the top, every earlier batch under it. We leave the old ones up. One certificate is a claim, a run of them is a record.

Why Eurofins does not test every mushroom batch
An outside panel with heavy metals, a pesticide screen, microbiology and mycotoxins runs into thousands of euros per product, per round. We make in small batches, so that cost would land on the price of every jar.
We do it the other way around. Our own lab measures every batch with the same methods a contract laboratory uses, and we publish the figures rather than a verdict. Eurofins then audits that work on a fixed schedule, and whenever we change something that could move a result: a substrate input, a step in the extraction, a supplier.
When they test, they receive part of a batch our own lab has already measured, and both sets of numbers go on the page. If the two ever disagree, you will read it here first.
What a certificate carries
What is measured, and the limit it is measured against, belongs to the product. A resin and a capsule are different matrices, with different panels, so each product page carries its own table rather than one table that would be wrong somewhere.
Two rules hold across all of them. Where EU law sets a maximum, we apply it and name the regulation. Where it sets none, as it does for total arsenic in food supplements, the certificate says the limit is ours.
| Question | On the certificate as | Where the limit comes from |
|---|---|---|
| Is it the species it says it is? | Identity, and which part of the organism | Our own specification |
| Is it strong enough? | The compound the product is standardised on: beta-glucans for the mushrooms, withanolides for Ashwagandha, fulvic acid for Shilajit | Product specification |
| Is it clean? | Lead, cadmium, mercury and arsenic. For Shilajit, some batches also carry an ethylene oxide screen, and a wider polycyclic aromatic hydrocarbon screen is run at the source roughly every two years | Regulation (EU) 2023/915, except total arsenic |
| Is it safe to eat? | Total plate count, yeasts and moulds, E. coli, salmonella | Our own specification |
| Is anything left from making it? | Residual ethanol from extraction | Our own specification |
The measured figures, the limits and the methods are on each product page, batch by batch. Which screens a given batch carries is shown there rather than assumed here.
A number, not a verdict
A pass tells you a batch cleared a limit you cannot see. The number tells you by how much, and lets you hold us against anyone else who publishes theirs.
