The clinically researched dose.
Not a fifth of it.
The nattokinase research everyone's quoting ran at 10,000 FU a day. Most bottles on the shelf hold 2,000. This one holds 10,000 FU per serving — printed on the front, not buried in the panel.
- 10,000 FU nattokinase from natto extract, per 3-capsule serving
- With CoQ10, aged garlic, turmeric, bromelain, grape seed & pine bark
- 240 vegetarian capsules — 80 full servings, about 3 months
- Non-GMO · no gluten, dairy or tree nuts · lab tested · cGMP facility

what's in this one
Why this works, and why most bottles don't
Cholesterol doesn't stack up on its own. It catches on fibrin — a sticky protein mesh that plaque builds itself upon.
They slow new material arriving. In the trials they held existing plaque roughly in neutral rather than clearing it.
The enzyme from fermented soybeans is fibrinolytic. It targets the mesh, not the cholesterol number.
10,800 FU/day moved plaque in the research. 3,600 FU/day didn't. Most shelf bottles hold 2,000.
Everything below is the long version, with the sources.
Four packs of natto a day. Or three capsules.
Heart disease kills over 700,000 Americans a year. In Japan it barely makes the list — and the most-cited explanation is a breakfast dish.
Fermented soybeans, eaten daily for over a thousand years. The bacteria that ferments them produces nattokinase, a fibrinolytic enzyme. You can absolutely get it from the food. Two problems.
I've been eating this for years, but the catch is you need to have at least 10,000 FU. That's basically like eating four or five of these every single day.
And the second one, which anybody who's actually tried it understands within one mouthful:
The first couple of mouthfuls almost made me vomit from the hideous taste and the smell that I have no words for.
That isn't a knock on the food. It's the entire reason the extract exists.
Cholesterol is the brick.
Fibrin is the mortar.
Everyone talks about cholesterol as if it stacks against your artery wall on its own. It doesn't. It needs something to hold onto.
That something is fibrin — a sticky protein mesh. Cholesterol drifts past your artery wall all day and, by itself, mostly keeps drifting. Add fibrin and it has somewhere to catch. Layer after layer, year after year.
Fibrin is — think of it as the network in which plaque builds itself upon. And so, by breaking it down, it makes it easier to collapse and remove the cholesterol.
— Dr. Kevin Ham, on how nattokinase works
If plaque is a wall, cholesterol drugs work on the bricks that haven't been laid yet. They slow the delivery of new material. They don't touch the mortar in the wall you already have.
“The car was in neutral.”
That's a physician, on camera, describing what high-dose statins actually did to arterial plaque in the big trials.
In a big study of high-dose statins… it only reduced the plaque by 0.015 millimeters. In some studies, the best results were a reduction of 0.04 millimeters.
Read that again. Neutral. Not reverse. Not clear. Hold in place.
For a lot of people that lands as a genuine shock, because nobody framed it that way at the appointment. Your numbers coming down and the wall in your artery coming down are two different events — and only one of them was ever on the table.
To be completely clear: none of this is a reason to stop, skip or reduce a statin you've been prescribed. That's your doctor's call, not ours and not a landing page's.
From neutral to a 36% reduction
A fraction of a millimetre. Progression halted; the existing wall largely unchanged.
Reported reduction in carotid plaque size and wall thickness — 1,062 people, 12 months.
One of these has a patent and is manufactured in a lab. The other comes out of a bowl of fermented beans. That difference explains a lot about which one comes up in a ten-minute appointment.
Being straight with you about the evidence: that 1,062-person study is a large retrospective analysis, not a placebo-controlled RCT, and you'll find people online arguing about it.
10,800 FU worked. 3,600 FU did nothing.
Same enzyme, same study, same twelve months. The only variable was dose — and the low-dose group's plaque didn't measurably move.

They gave you a score. They didn't give you a plan.
A calcium score arrives with a number and almost no instructions. And there's something about that number worth understanding — not to dismiss it, but to read it properly.
A coronary calcium score counts hardened, calcified plaque. That material is essentially bone, and it does not move quickly. The softer, non-calcified plaque is a different matter.
So your score isn't wrong. It's incomplete. Keep the scans, keep the appointments, and set your expectations accordingly.
What you actually control between now and the next scan is the months in between. That's the entire argument for starting something daily rather than waiting for the follow-up to tell you what to do.
Your arteries are least protected at 6:30 in the morning.
Your body already runs its own clot-clearing system. It doesn't run at a constant speed. It runs on a clock.
A protein called PAI-1 is the brake on that system, and PAI-1 peaks around 6:30 AM. Your natural fibrin-clearing activity is weakest in the early morning, which is also when cardiac events cluster.
PAI-1 activity across 24 hours
Long-term users worked this out by instinct, without ever being handed the reason:
Generally, one takes nattokinase on an empty stomach; often at night, as nighttime is when clotting issues happen most often. So, I've been taking these at bedtime.
Every bottle ships with the timing protocol on the insert. And when circulation improves generally, people tend to notice it in the extremities first.
It isn't a blood thinner. It's a brake release.
Most people picture nattokinase as a drain cleaner chewing through fibrin directly. That's the weaker of its two routes.
Memorial Sloan Kettering's monograph is explicit: nattokinase's dominant pathway is cleaving and inactivating PAI-1 — that same brake.
So the honest description isn't “this thins your blood.” It's this releases a system you already own and already run every night.
This is a mechanism statement, not a safety clearance. Nattokinase carries real bleeding-interaction considerations. If you take warfarin, Eliquis, aspirin or any anticoagulant, speak to your doctor first.
10,000 FU, and six things chosen on purpose
Most brands bundle extra botanicals to make a label look busy. Here's the reasoning behind each of ours.
One honest limitation. The 500 mg supporting blend is proprietary, so we can't publish exact milligrams per botanical.
Statins block HMG-CoA reductase — the same pathway that makes CoQ10, the coenzyme heart muscle runs on. Relevant whether you're staying on yours or not.
One of the very few natural compounds with human CT-imaging data on arterial plaque behind it.
A proteolytic enzyme that works alongside nattokinase rather than competing with it.
For the inflammation side of the picture, which fibrin alone doesn't cover.
Two of the better-studied polyphenols for vascular support.
A traditional supporting botanical rounding out the blend.
The full panel, before you buy
You're the kind of person who reads this first. So here it is.
Start gentle, or go straight to the full serving
Each capsule carries roughly 3,333 FU, so the bottle scales with you.
Plenty of people start with one capsule for the first week or two and work up — particularly anyone who runs low blood pressure. Others go straight to three. The 240-count bottle supports either without buying a second product.
Label instruction is preferably with meals. Many long-term users take theirs on an empty stomach or at bedtime instead. Pick the version you'll keep doing for months.
A lower number on the next scan
Not “feeling healthier.” A specific, measurable, doctor-verified drop.
“Family history on both sides, and I'd been saying no to a statin for years without having anything else to say. At least now I've got something to bring to the appointment instead of just an argument.”
“My husband and I both take it. What sold me was the FU being on the front of the bottle instead of hidden in the small print, and that 240 capsules actually lasts long enough to matter.”
“I'd been on 2,000 FU for a long time and just assumed that was the dose. Read the actual paper, moved up to 10,000. I only wish I'd turned the old bottle over three years ago.”
Individual experiences. Not typical, not guaranteed, and not a promise of any specific outcome.
This is not for everyone
We'd rather you skip it than buy for the wrong reason and want your money back in week three.
- You're on a prescribed anticoagulant and haven't spoken to your doctor. This is not a replacement for that medication, ever.
- You want something to happen in a week. This is a months-long daily habit or it's nothing.
- You expect a capsule to undo a diet, a smoking habit, or twenty years of skipped appointments.
- You have a soy allergy — nattokinase is made by fermenting soybeans.
- You want the cheapest nattokinase online. That bottle exists. It's 2,000 FU.
- Heart disease runs in your family and you'd like to be the first one who looked into it.
- You've got a scan result or a set of numbers and no actual plan to go with them.
- You've been offered a statin and want to understand what it does and doesn't do first.
- You already take nattokinase and have never checked the FU on the bottle.
- You read the supplement panel before you read the marketing.
Get the dose the research used
One bottle is 80 full servings — about two and a half to three months. Most people take the middle option, because that's roughly the span between one scan and the next.

Six months. That's deliberate.
This isn't a thirty-day product and we won't pretend it is. A fair trial of a fibrinolytic enzyme is months, not weeks — which is exactly why the window is 180 days instead of the usual one.
Take it daily, give it a real run, and if you're not glad you did, email us and we'll refund you. No empty bottle to mail back, no explanation required.
HaloraCo is sold here. Only here.
We don't sell on Amazon or any marketplace. If you find a bottle with our name on it there, it isn't ours — and we can't tell you what's in it or honour the 180-day refund on it.
This matters more in this category than most. People here check who funded the study and pull the manufacturer's address up on Google Earth before they buy.
The questions we actually get
Is it safe with my blood thinner?
Ask your doctor first, and don't stop or reduce a prescribed anticoagulant on your own. This is the one question on this page where we won't hand you a reassuring answer to close a sale.
The mechanism section explains why nattokinase isn't technically a “thinner” — but a mechanism explanation is not a safety clearance. Bring the bottle to your appointment and let your doctor make the call.
The big study wasn't a placebo-controlled RCT. Doesn't that matter?
It does, and you should know it going in. The 1,062-participant carotid study is a large retrospective analysis, and questions have been raised about its funding.
What makes it hard to wave away is the internal comparison — the high-dose and low-dose groups behaved very differently within the same dataset.
Lumbrokinase is supposed to be far stronger. Why this?
Because raw fibrinolytic force probably wasn't the bottleneck. If the dominant pathway is releasing PAI-1's grip on the system you already run, “30× stronger” answers a question nobody asked.
Nattokinase is also far more consistently standardized between batches and brands, which is what makes an FU number on a label mean anything at all.
Will it drop my blood pressure too much?
Some people report feeling lightheaded, especially starting at a full serving. That's part of why the bottle scales — each capsule is roughly 3,333 FU, so you can start at one and work up.
Why a proprietary blend? I want exact milligrams.
Fair — it's the most common criticism from the people whose opinion we care about most. The 500 mg supporting blend is proprietary, so we can't publish the split of each botanical inside it.
What is disclosed precisely is the part that matters: 500 mg of nattokinase from natto extract, standardized to 10,000 FU per three-capsule serving.
Morning, night, with food?
The label says preferably with meals. In practice long-term users split two ways: empty stomach at least 30 minutes before eating, or at bedtime.
How long before I'd notice anything?
Honestly, most people don't feel much day to day. This isn't caffeine. The outcomes in the research were measured over twelve months on imaging, not two weeks on sensation.
I had symptoms my doctor said were nothing. Is this relevant?
If a symptom is bothering you, keep pushing for an answer from a clinician — a supplement is not a substitute for a diagnosis.
Allergens and other ingredients?
Contains soy — nattokinase comes from fermented soybeans, so there's no version without it. Free of gluten, dairy and tree nuts. Non-GMO, lab tested, made in a cGMP facility.
Go turn your bottle over.
If it says 2,000 FU, you now know why the last few months didn't move anything. And if you've never taken it at all, you know what number to start at — and why it's that number and not a smaller one.
