36%. That’s the number Henoura Nattokinase is built around. Not “supports circulation,” not “may help with blood flow.” An exact figure, reduces arterial plaque by 36%, sitting right in the ad copy like it came straight out of a lab report.
Numbers that specific make good marketing precisely because they sound unarguable. So I went looking for where it actually came from.

What’s Actually in Henoura Nattokinase
Yes. Nattokinase is an enzyme pulled from natto, fermented soybeans that have been part of Japanese cooking for centuries, and it’s been studied in real human trials for blood pressure and blood clotting. This isn’t an invented ingredient wrapped in fake credibility. That part of the pitch is legitimate.
The 36% Number Doesn’t Belong to This Product
A real study, just not one that tested this product. Eighty-two people enrolled, seventy-six finished, and the group taking nattokinase showed measurable plaque improvement after 26 weeks. Good study, real result. But that trial used 6,000 FU of nattokinase daily. Henoura’s capsules deliver 10,000 FU per serving. Different dose, different formula, and Henoura Nattokinase itself was never in that study.
So the ingredient earned that number. Henoura is just wearing it. Two other independent reviewers landed on this exact same mismatch before I did, which tells me it’s sitting right there in the numbers for anyone who checks, not a stretch of a read.
A Very New Brand With No Track Record
Very. This isn’t rotating-domain, disposable-landing-page new like some of the products we’ve covered here. It’s just genuinely young, with almost no independent track record beyond the company’s own marketing and the one borrowed statistic doing most of the persuasive work.
The Blood Thinner Risk Nobody’s Advertising
Depends what else you’re taking. Nattokinase works by affecting how blood clots, that’s the entire mechanism behind its circulation benefits. It also means anyone already on a blood thinner or antiplatelet medication is looking at a real, meaningful bleeding risk if they add this on top. That’s not a minor footnote to skim past. If that’s you, this is a conversation for your doctor before it’s a purchase decision.
No False FDA Claims Here, For Once
No, and credit where it’s due. Henoura doesn’t claim FDA approval anywhere, which is honestly more restraint than some of the products we’ve reviewed in this series have shown.
Is Henoura Nattokinase a Scam?
No. Overhyped is the more accurate word. The ingredient is real. The underlying research is real. What’s misleading is a real study’s results getting attached to a product that was never tested at that dose. That’s a quieter problem than a fake doctor or a fabricated founder story, easier to miss, but it’s still the wrong number stuck on the wrong bottle.
Final Verdict
The enzyme is real. The research on it is real. What’s not real is Henoura earning that 36% number itself, it borrowed someone else’s trial at someone else’s dose. If you’re weighing this one, know what’s actually being sold: a legitimate ingredient, an unproven finished product, and a genuine reason to check with your doctor first if blood thinners are already part of your routine.
Henoura Nattokinase FAQ
Does Henoura Nattokinase really reduce arterial plaque by 36%?
That number comes from a study using 6,000 FU of nattokinase daily for 26 weeks. Henoura provides 10,000 FU per serving and was never tested in that study, so the claim doesn’t transfer directly to this product.
Is nattokinase safe to take?
It affects blood clotting, which can meaningfully raise bleeding risk for anyone on blood thinners or antiplatelet medication. Talk to a doctor first if that applies to you.
Is Henoura Nattokinase FDA approved?
No, and it doesn’t claim to be. Dietary supplements aren’t FDA-approved as a category.
How is Henoura different from other nattokinase supplements?
It’s dosed higher (10,000 FU) than the study behind its headline claim (6,000 FU), and it’s a newer brand with limited independent history, similar to how our Hormovance review found a brand leaning on borrowed credibility rather than its own evidence.
