How Natural Foundation Tests Every Batch
From our GMP manufacturing facility in Oxford to the independent testing lab and then to your door — here's exactly how Natural Foundation ensures every batch of Nattokinase meets the highest standards of quality and transparency.
-
Batch production in our GMP facility
Every production run of Natural Foundation Nattokinase is manufactured in-house at our GMP-certified facility in Oxford. Each run is assigned a unique batch number that's printed directly on your bottle.
-
Independent third-party laboratory testing
Before any batch ships, samples are sent to independent ISO 17025 accredited laboratories for a comprehensive panel of tests. Natural Foundation does not test in-house — all testing is fully independent and third-party.
-
Full results published publicly
The complete, unedited lab report for every batch is uploaded to the Natural Foundation public testing portal. Nothing is hidden, nothing is redacted, and nothing is selectively published.
-
Scan your bottle and verify
Every bottle includes a QR code that links directly to the test results for your specific batch. You can also enter your batch number manually on the testing portal to view your results.
