The only cardiovascular brand that 3rd-party tests every batch.
We tested 7 of America's top-selling Nattokinase brands. Every single one was underdosed — one had just 17.8% of what was on the label. So we built the one we'd take ourselves: manufactured in our own facility, independently lab-verified every batch, every certificate published online.
We test every batch, then publish the results.
The supplement industry's dirty secret is that most brands never test what they sell. We do the opposite. Every batch we manufacture is sent to SORA Labs, an ISO 17025:2017 accredited third-party laboratory, before it ever reaches your door. Every Certificate of Analysis is published online — scannable, searchable, and free to view.
Raw ingredients tested on arrival
Every raw ingredient is tested for heavy metals, microbials, and potency before it enters our Oxford facility. If it fails, it never goes into production.
Manufactured in-house under GMP
We don't outsource to contract manufacturers. Every capsule is made in our own GMP-certified UK facility in Kidlington, Oxford — fully traceable, batch by batch.
Finished batch tested independently
A sample from every finished batch goes to SORA Labs for third-party verification. Potency, purity, heavy metals, microbial contamination — all tested by an accredited lab with zero ties to us.
Certificate published before shipping
Every Certificate of Analysis is uploaded to our public testing database. Scan the batch code on your bottle and read the exact lab report for the capsules in your hand.
ISO 17025:2017
ACCREDITED
VERIFIED
We tested 7 of America's top brands. All 7 were ripping people off.
We bought the best-selling Nattokinase pills on Amazon and sent them to SORA Labs (ISO 17025:2017) — the same accredited laboratory we use for our own batches. Same enzyme assay. Same lab. Same day.

All testing performed by SORA Labs (ISO 17025:2017). 7 out of 7 competitor brands delivered less than what they promised on the label. One brand had just 17.8% of label claim — meaning if you paid $30, you got $5 worth of actual product. The rest? Filler.

Every American over 40 should know about this.

Things people ask us.
Three things that almost nobody else does — and certainly not all three together.
One: we manufacture in our own GMP-certified facility. We don't subcontract to a third-party blender, which means we control what goes in the capsule, the dose, and the quality of the raw material. Two: every single batch is tested by an independent ISO 17025-accredited laboratory before it ships. Not once a year. Not on samples we cherry-picked. Every batch. Three: we publish every certificate of analysis online, searchable by the batch number printed on your bottle. If you can't verify it, we don't sell it.
