Description
Kinaru Nattokinase delivers 10,000 FU of nattokinase — the clinically studied dose, the amount the plaque-reversal research actually used — in one small vegetarian capsule. Nattokinase is a fibrinolytic enzyme from fermented soybeans: it breaks down fibrin, the mesh that arterial plaque builds itself on. Stacked with CoQ10, bromelain, turmeric, aged garlic, pine bark and grape seed extract. Non-GMO, gluten-free, third-party lab tested, made in the USA. 30 vegetarian capsules per bottle (30-day supply).
The Results
Most customers notice changes in circulation — warmer hands and feet, less heaviness in the legs — within the first few weeks. Bloodwork moves more gradually: the research that measured plaque reduction ran for a full year. Nattokinase works with your body's own fibrinolytic process, so results are steady rather than sudden. For best results, take one capsule daily for at least 3–6 months.
90 Day Guarantee
Try Kinaru completely risk-free. Take it every day for 90 days and get your bloodwork done. If your numbers haven't moved and you don't feel a difference, return it for a 100% refund — empty bottle included, no questions asked. We're not asking you to believe us. We're asking you to test it.

My doctor read it twice"My LDL sat at 186 for two years no matter what I cut. Started this in January — one capsule, nothing else changed. Last panel: 88. My doctor asked me what I'd done."

No statin conversation this year"I walked into my physical expecting the prescription talk. Didn't get it. First time in four years I left that office without something new to pick up at the pharmacy."

Common questions we hear from customers
How do I take Kinaru?
One capsule daily with a glass of water, preferably with a meal. That's the whole routine.
I'm on a blood thinner or daily aspirin. Can I take this?
Talk to your doctor first. Nattokinase works on fibrin — the same pathway as warfarin, Eliquis, Xarelto and aspirin — so the effects can stack. Same applies if you have a bleeding disorder or surgery coming up. This is the one real interaction with this ingredient and we'd rather you hear it from us.
Can I take it alongside my statin?
Most people do. A statin lowers how much cholesterol your liver produces. Nattokinase works on fibrin, the mesh plaque builds on. Different mechanism, different target. Tell your doctor what you're taking, and never stop a prescription on your own.
Aren't all nattokinase supplements the same?
No. In the research, reversal only appeared at high doses — below roughly 6,000 FU, studies found nothing. Almost every bottle on the shelf sits under 2,000 FU. Ours is 10,000 FU in a single capsule.
When will I see results?
Circulation changes show up first, often in 3–5 weeks. Bloodwork moves more slowly — the study that measured plaque reduction ran a full year. Covered by our 90-day guarantee either way.
Why not just eat natto?
You'd need four or five packs a day to reach this dose, and the smell is the reason most people quit in week one. The enzyme is isolated so you get the studied amount without the breakfast.
Why Plaque Isn't a Willpower Problem
Plaque doesn't build on cholesterol alone. It builds on fibrin — a protein mesh inside the artery wall that catches cholesterol and holds it there while it hardens. Cut all the red meat you like: if the mesh stays, so does the plaque.
- Numbers that won't come down no matter what you cut
- Cold hands and feet, heavy legs on the stairs
- A statin that stopped the climb but never reversed it
- That "am I next?" feeling every time a parent comes up
Take apart the scaffold, not just the symptom
Kinaru's 10,000 FU nattokinase is fibrinolytic — it breaks down the fibrin mesh that arterial plaque builds itself on, at the dose the research actually used.

How arterial plaque shows up over time
1
The Silent Build
Nothing hurts. Nothing warns you. Fibrin lays down inside the artery wall and cholesterol starts catching in the mesh — through every year you felt completely fine.
2
The Narrowing
Cold hands. Heavy legs. A pause halfway up the stairs you didn't used to need. The channel is smaller than it was, and your body starts economising.
3
The Conversation
A scan, a number, a prescription — and a drug that halts the climb without reversing it. The plaque stops growing. It doesn't leave.
Arterial flexibility declines with age
The Hidden Driver Behind Hardening Arteries
Your body makes its own fibrin-clearing enzymes — and makes less of them every decade. As clearance falls behind buildup, the mesh thickens and the artery stiffens. Quietly, year after year.

"My brother needed a stent at 54 and that was my wake-up call. Eight months on this and my last panel was the best it's been since my forties. I don't dread the blood draw anymore."

"I'd tried three other nattokinase brands and felt nothing. Turns out they were all under 2,000 FU. This is the first one at the actual studied dose, and it's the first one that did anything."

"One capsule instead of the three my last brand wanted, and no aftertaste at all. My wife takes it now too. Simplest thing I've added to my routine in years."
