Three capsule of clinically studied Nattokinase — the fibrinolytic enzyme your body uses to break down the fibrin that hardens arteries with age.
"The pattern I see constantly is people in their 50s and 60s treating circulation like an on-off switch — either you have a problem or you don't. But circulation declines gradually. The cold hands, the heavy legs at the end of the day, feeling puffed on stairs you used to walk up easily — that's the middle ground nobody addresses. Nattokinase supports the body's natural fibrin balance, which is central to how freely blood moves. The people who take it consistently tend to notice the difference in their daily energy before anything else."
We don't want to be another disappointment. That's why we give you 90 full days — not 30, not 60 — to feel the difference. No results? Full refund. No questions. No hassle. We're that confident.
Most people don't feel a thing until the day something goes wrong. Here's what's actually building up inside your arteries right now.
As you age, your body's natural clot-clearing system slows down. Fibrin strands bind to cholesterol and calcium, forming sticky plaque along artery walls.
The buildup thickens the walls and shrinks the channel. Blood viscosity rises, forcing your heart to work harder to push flow through.
Restricted flow means less oxygen to the heart, brain and legs — showing up as fatigue, cold extremities, brain fog and, eventually, real danger.
The problem isn't just cholesterol — it's the fibrin holding it all in place. That's exactly what Nattokinase is studied to break down.
It's one of the strangest facts in modern health. Same century. Same medicine. Wildly different outcomes.

It isn't genetics. When Japanese families moved abroad and adopted a Western diet, the advantage faded within a generation or two. The genes didn't change. The food did.
It isn't the healthcare. The West spends far more per person on medicine than Japan does — and still comes out behind.
Which leaves one answer.
It's what's on the plate.
Built around the enzyme with the most cardiovascular research behind it — then supported at every stage of the process, from clearing what's there to keeping the vessels open once it's gone.
A fibrinolytic enzyme discovered in traditional Japanese natto. It degrades fibrin directly and supports your body's own clot-dissolving pathway. Most bottles stop at 2,000 FU. This runs five times that.
Hero · 10,000 FUA second natural enzyme working alongside the nattokinase, breaking the same protein buildup apart from another angle. The smallest vessels clear last — two enzymes together is how you reach them.
Enzyme supportTargets the chronic inflammation that triggers the patching in the first place. An inflamed vessel is a stiff vessel — this addresses what's causing the buildup, not just what's already there.
InflammationFuels the pump. Your heart muscle is what pushes blood through the narrowest vessels in your body, and CoQ10 is what it burns to generate that force — so the process doesn't stall out.
Cellular energyKeeps blood flowing clean and smooth rather than thick and sticky. It doesn't matter how clear the pipe is if what's moving through it moves like syrup.
Blood flowRepairs and protects the vessel walls underneath once the buildup clears. A vessel that's been stiff for twenty years has to relearn how to open — this is what makes it last.
Vessel repair
Fibrin binds to cholesterol and calcium, forming dangerous blockages that restrict blood flow.
The enzyme degrades fibrin and activates plasminogen — your body's natural clot-dissolving system.
Blood vessels strengthen and heart function improves for long-term cardiovascular health.
Statins and blood thinners have their place — many people take them under a doctor's care. Here's how a daily nattokinase compares as a natural, everyday circulatory support.
| Cortéa Nattokinase | Statins | Blood Thinners | Generic Nattokinase | |

*Side effects reported in published literature; not everyone experiences them. **Based on independent lab testing of leading marketplace brands. Cortéa is a dietary supplement, not a replacement for prescribed medication — never stop a prescription without talking to your doctor.
Research shows nattokinase works gradually — this is why we recommend staying consistent for a full 12 months.
Years of fibrin, cholesterol and calcium have narrowed the artery. Flow is restricted.
Nattokinase actively breaks down fibrin. Blood viscosity and circulation begin to improve.
Artery wall thickness reduces. Cholesterol improves. Vessels become more elastic.
In studies, wall thickness dropped from 1.33mm to 1.04mm and plaque reduced up to 36%.
Based on a 12-month study of 1,062 participants at 10,800 FU/day.
A once-daily capsule for cardiovascular support containing 10,000 FU of Nattokinase alongside Bromelain, Tumeric, CoQ10, Aged Garlic Extract and Pine Bark Extract — clinically studied and traditionally used ingredients for heart and artery health.
A fibrinolytic enzyme derived from natto, a traditional Japanese fermented soybean food eaten for centuries and widely researched for its role in supporting healthy circulation and breaking down fibrin.
Statins are prescription medications that lower cholesterol production in the liver. Nattokinase is a natural enzyme that targets fibrin — the protein that binds plaque together — and supports vessel elasticity. It's a dietary supplement, not a medication, and it's not a replacement for anything your doctor has prescribed. If you're on a statin or blood thinner, talk to your doctor before adding it.
One capsule per day with water, ideally with a meal. Consistency is what matters most.
Some people notice changes within a few weeks, but the published research shows full benefits build over a 12-month course. That's why we recommend the autoship plan.
If you take any medication — especially blood thinners or blood pressure medication — consult your doctor before starting. Nattokinase supports blood flow, so your doctor may want to monitor you.
Yes — vegetable capsules with no animal-derived ingredients. It contains soy (from the natto). Free from gluten, dairy, nuts, artificial colours and preservatives.
Anytime — no lock-in and no penalty. And every order is backed by our 60-day money-back guarantee.
