TESTING & QUALITY
Every batch, tested.
Mushrooms are absorbers. They take up what is in the substrate they grow in, and that includes heavy metals. It is the fair question to ask of any mushroom supplement, and most brands will not answer it.
So here is our most recent batch, in full.

Heavy metals
Tested on the finished gummy, not on the raw extract. These are the numbers that matter most in this category.
| Test | Result | Limit |
|---|---|---|
| Lead | Not detected Pass | — |
| Mercury | Not detected Pass | — |
| Arsenic | 0.06 ppm Pass | 1.0 ppm |
| Cadmium | 0.01 ppm Pass | 1.0 ppm |
"Not detected" means the result fell below the laboratory's limit of detection. Where the limit column reads —, the certificate of analysis does not state a numerical limit for that metal.
Microbiology
Pathogen screening on the finished product, carried out on the same batch.
| Test | Result | Specification |
|---|---|---|
| E. coli | Negative in 25g Pass | Absent in 25g |
| Salmonella | Negative in 25g Pass | Absent in 25g |
| Staphylococcus aureus | Negative in 25g Pass | Absent in 25g |
| Total viable count | Less than 10 cfu/g Pass | 10,000 cfu/g |
