What customers say
Every review shows how long the person had been taking it when they wrote in, because with circulation that changes what the words mean.
Part of my routine now
"I had been keeping an eye on my heart for years and tried a lot of things that did nothing. About nine weeks in I noticed I had stopped pausing at the landing on the stairs, and my last check-up left me and my doctor both pleased. It is part of my morning now, same as the rest of them."

Like a switch flipped
"Around week five it was like a switch flipped. My feet stopped being cold in bed, which my wife noticed before I did, and the energy came back in a way I had honestly given up on. I only wish I had known to be patient through the first fortnight, because for three weeks I felt nothing at all."

Everything I was buying separately
"Fish oil, CoQ10 on its own, garlic capsules, beetroot powder. Four bottles on the counter and nothing stacked together properly. This is the first one that actually hits all the things I was paying for one at a time, at the dose the study used, with the certificate right there on the page. Energy back. Cold hands gone."

My ankles at the end of the day
"I sit for work and by five o'clock my ankles used to have a sock line pressed into them. That is mostly gone. I write the numbers down every Sunday morning in the little log book that came with it, and my doctor asked to see it at my last appointment, which has never happened before in twenty years."

I took the panel to my cardiologist
"I printed the ingredient panel and the certificate and put them on the desk in front of him, because I am on a blood thinner and I was not going to guess. He read it, asked about the vitamin K, and we sorted it out between us in about four minutes. I have never been able to do that with a supplement before."

I want to see my grandkids grow up
"I have four grandchildren and I want to be there for them, so I take this seriously. Six weeks in my hands are warm, I am sleeping through the night, and I have the energy to keep up with them on a Saturday. That is what I was actually buying. Take them with food and you will have no trouble."

Five actives. Each one owns a job.
Most cardiovascular supplements bury one weak ingredient in a ten-name proprietary blend. This does the opposite: five clinical-dose actives, each targeting a specific failure point behind high blood pressure, blood sugar instability and heart decline after 50.

10,800 FU
Liposomal NSK-SD Nattokinase
The fibrinolytic enzyme, at the exact dose used in the twelve-month, 1,062-participant study. Liposomally encapsulated, because enzymes are proteins and proteins are fragile in a stomach.

3,000 MG
Beetroot Extract
Works through the nitric oxide pathway. Pooled evidence across 22 trials puts the systolic effect at 3.55 mmHg, rising to 5.31 in participants already hypertensive.

200 MG
Coenzyme Q10 (Ubiquinol)
The cofactor your mitochondria run on, and the one statins deplete through the same reaction they use to lower cholesterol. Ubiquinol is the reduced form, because conversion efficiency declines with age.

200 MCG
Vitamin K2 (MK-7)
Activates Matrix GLA Protein. Directs calcium toward bone rather than artery wall. MK-7 has a half-life measured in days, not the 90 minutes of the older MK-4 form.

500 MG
Berberine HCl
Supports glucose and lipid handling through AMPK activation, at the dose used in the clinical work.
30-day risk-free
Iron-clad guarantee
One full bottle to judge it on. If it is not for you, full refund, and do not send anything back.
The hidden problem
How arteries stiffen after 50, and why the standard prescription misses it
The cleanup system in your arteries does not retire. It gets held back, and nothing in a standard prescription releases it. Here is the sequence, and where the treatment stops short.
01
Peak vascular capacity · 20–35
Fibrinolysis runs freely. Arteries stay flexible. Calcium goes to bone, where it belongs.
02
The brake goes on · 35–50
PAI-1 production climbs. It is the compound that inhibits fibrinolysis, a safety mechanism working harder than it needs to. Fibrin starts accumulating faster than it clears. You do not feel it yet.
03
The number starts climbing · 50+
Stiffer arteries force the heart to push harder. Your doctor prescribes lisinopril. It lowers the reading. It does not soften the wall that raised it.
04
The statin trap
Statins lower cholesterol by inhibiting the mevalonate pathway, the same route your body uses to make CoQ10. The depletion is documented across every statin and every dose. The fatigue gets blamed on age.
05
The event that was not sudden
Fibrin, arterial calcium and mitochondrial depletion arriving together at what gets called out of nowhere. It was not. It was thirty years of four processes, three of which nobody was treating.
The evidence
Studied longer than most of what is in your cabinet
Nattokinase is not experimental. It was isolated in 1980 and has been eaten daily in Japan for a thousand years.

PLAQUE REDUCTION
Carotid plaque size decreased by up to 36% at 10,800 FU daily. Intima-media thickness fell from 1.33 mm to 1.04 mm.
3,600 FU
THE DOSE THAT DID NOT WORK
The same study tested a lower dose. No measurable effect on lipids. No suppression of progression. Most of the shelf sits here.

LABEL ACCURACY
Our launch batch measured 11,040 FU against a 10,800 FU claim, inside ConsumerLab’s 100 to 135% pass window.
The real difference
Two ways to get the dose wrong
Cheap nattokinase and high-dose nattokinase look like opposite mistakes. They are the same mistake.

The BlueOrganics compound
BlueOrganics Cardiovascular Complex
Five clinical-dose actives covering four mechanisms of cardiovascular decline: fibrin clearance, blood pressure, calcium routing, and the metabolic and mitochondrial side. Built around liposomal NSK-SD nattokinase at 10,800 FU per serving, the exact dose carried through the largest human study on the compound, and the only dose in this category with twelve months of outcome data behind it.
Where standard prescriptions address one number at a time, this addresses four failure points at once: fibrin buildup, arterial calcium, metabolic control, and the CoQ10 depletion statins cause.
Four mechanisms, one capsule line
Fibrin clearance. Nattokinase is fibrinolytic. It acts on fibrin already deposited, which is a different job from preventing the next clot.
Blood pressure. Beetroot works through the nitric oxide pathway, the most replicated blood pressure mechanism in the category.
Calcium routing. K2 as MK-7 activates Matrix GLA Protein, directing calcium toward bone rather than arterial wall.
Metabolic and mitochondrial. Berberine supports glucose and lipid handling. CoQ10 as ubiquinol replaces what the mevalonate pathway stops producing under a statin.
What to expect
Circulation compounds rather than spikes. Beetroot acts fastest, sometimes inside a fortnight. Nattokinase reaches full plasma activity around week three. Berberine and CoQ10 accumulate over eight to twelve weeks.
Most people report small physical changes rather than dramatic ones: warmer hands and feet, less heaviness in the legs at the end of the day, less ankle swelling after sitting.
This is a supplement, not a treatment. It does not replace anything you have been prescribed.

The difference
Why this one and not the cheaper one
You are getting the patented NSK-SD nattokinase strain, the same Japanese isolate used in the published research, at the dose that research actually tested, liposomally encapsulated so it survives the trip.
Every batch is third-party tested for FU activity, heavy metals and microbial contamination, and every batch certificate is published rather than available on request. No proprietary blends. No filler dosing. No number on the front that nobody has verified.

The protocol
Your 12-week arc
Circulation is not a three-day fix. It compounds. Here is what to expect and when.
Step 01 · Days 1–14
Getting started
Two capsules daily with food. Beetroot works through nitric oxide and acts fastest, so some notice warmer hands and feet inside the first fortnight. Most notice nothing yet. This is the fortnight people quit. Do not.
Felt benefits: days 7–14
Step 02 · Weeks 3–6
Full activity
Nattokinase reaches full plasma activity around week three. This is where circulation changes tend to show first: cold extremities, ankle swelling after sitting, heaviness in the legs at the end of the day.
Felt benefits: week 3+
Step 03 · Weeks 6–12
The compound effect
Berberine’s metabolic effects accumulate over eight to twelve weeks. CoQ10 rebuilds gradually. Calcium routing is slower still, measured in cohort studies over years rather than weeks.
Felt benefits: sustained
One bottle to decide. Keep it either way.
This works on a twelve-week clock, not a three-day one, so we are not going to pretend one bottle tells you everything. What one bottle does tell you is whether it suits you, whether the capsules go down easily, and whether the certificate says what we said it says.

Frequently asked questions
The questions we actually get, answered by the people who built the formula.
Yes, and it is the reason CoQ10 is in the formula. Statins lower cholesterol through the mevalonate pathway, which is the same route your body uses to make CoQ10. Tell your prescriber you are taking it.
Speak to your prescriber first. This contains vitamin K2, and vitamin K is the warfarin antidote, so warfarin patients are asked to keep vitamin K intake steady rather than change it. The newer anticoagulants do not carry that interaction.
Beetroot’s pooled effect across 22 trials is around 3.55 mmHg systolic, rising to 5.31 in people already hypertensive. Modest by design. If you are on blood pressure medication, monitor as usual and tell your prescriber.
Different job. Fish oil affects some inflammatory markers. It does nothing for fibrin already deposited in the arterial wall, which is the mechanism nattokinase acts on.
Because 10,800 FU is the only dose with twelve months of human outcome data behind it. The same study tested 3,600 FU and found no measurable effect. Above 10,800 FU, the research stops. A bigger number on the front is not more evidence.
Ubiquinol is the reduced form and absorbs better. Your body converts ubiquinone into ubiquinol before it can use it, and conversion efficiency declines with age, which is exactly the group taking this.
Beetroot inside two weeks for some people. Nattokinase reaches full plasma activity around week three. Berberine and CoQ10 accumulate over eight to twelve weeks. Most people report small physical changes rather than dramatic ones.
No. It is not suitable during pregnancy, and you should discontinue well before any scheduled procedure. Tell your surgical team what you are taking.
