The 10,800 FU Nattokinase Study: What Researchers Found in 1,062 Participants
Why does 10,800 FU keep appearing in conversations about nattokinase?
There is a reason.
In 2022, Chen and colleagues reported a retrospective investigation involving 1,062 participants followed for 12 months.
What researchers reported
Participants receiving 10,800 FU/day showed significant changes across the reported lipid and carotid measurements after 12 months.
A comparison group receiving 3,600 FU/day did not show comparable significant changes in those reported measurements.
Put simply:
Dose mattered in the Chen study.
The two activity levels did not produce the same reported findings.
What that means — and what it doesn't
What PBE learned
For PBE, the important lesson is bigger than the number itself.
The study reinforces the importance of asking:
How much measured activity are we actually delivering?
That question became part of a larger product-development framework:
Takeaway
10,800 FU matters because it has a specific human-research history — not because every product carrying a similar number becomes equivalent to the study.
PB Natto
PBE took the activity question further by combining a high-activity, single-capsule formulation with acid-resistant delivery and planned finished-product activity verification.
