Verified. Not Just Labeled.
Four claims we don't ask you to take on faith.
What's On The Label Is What's In The Capsule.
Every production batch is third-party tested for actual fibrinolytic activity before it ships — not self-reported, not assumed.
Dosed At The Clinical Threshold. Not A Guess.
Independent testing (ConsumerLab, Nov 2024–Jan 2025) found most nattokinase brands deliver 40–60% of their labeled potency.
From Real Japanese Natto. Not A Synthetic Isolate.
Sourced from the same traditionally fermented soybean base consumed daily in Japan for over 1,000 years — not a lab-synthesized substitute.
Always Third-Party Tested. Published, Not Hidden.
A Certificate of Analysis is available for every batch on request — because a category with documented label fraud doesn't get the benefit of the doubt.
Trusted by Athletes.
Backed By Research.
This Is A Clinical Dose.
Not A Guess.
Family Owned. U.S. Owned.
We didn't build Byze because we spotted a supplement trend. We built it because someone we love got worse on medication that was supposed to help — muscle pain that wasn't there before, a mind that didn't clear until noon, a doctor who called it "manageable" after four minutes.
So we asked the only question that mattered: why are people on statins for ten years still having heart attacks?
Most nattokinase on shelves delivers a fraction of the dose used in the trials that actually moved the numbers. We couldn't sell that to our own family — so instead of building a brand, we built the one supplement we needed to exist.
No outside investors. No board to answer to. Every batch third-party tested and published. We say what this does, what it doesn't, and why — every time.
