Most heart supplements focus on cholesterol. But cholesterol isn't the whole story.

Circulene targets fibrin — the sticky protein that traps cholesterol and debris inside your artery walls. It's what most solutions ignore completely.

Nattokinase supports your body's natural ability to break down this buildup, promoting clearer arteries, healthier blood flow, and real cardiovascular protection.

The Silent Killer Inside Your Arteries

Cardiovascular disease is the #1 cause of death worldwide. Every 40 seconds, someone in the U.S. has a heart attack. Every 3.5 minutes, someone dies from a stroke.


But here's what makes it dangerous: most people don't know it's happening until it's too late.


Plaque builds silently inside your arteries for 20, 30, even 40 years—with no symptoms. By the time you feel something, the damage is already done.

What's Actually Clogging Your Arteries?

It starts with fibrin, a sticky protein that clings to your artery walls like wet cement.


Your body has a built-in system to clear it. But inflammation, aging, and blood sugar issues block that system from doing its job.


So fibrin keeps accumulating. It traps cholesterol particles inside the wall. They oxidize and harden. Layer after layer, year after year, with zero symptoms.


⚠️ Your arteries narrow.
⚠️ Blood flow weakens.
⚠️ Pressure builds.


Then one day, a piece breaks loose. If it reaches your brain, it's a stroke. If it reaches your heart, it's a heart attack.


Nattokinase delivers the fibrin-dissolving enzyme that supports your body's natural cleaning system, helping clear what's already stuck before it becomes a crisis.

A Natural Enzyme That Breaks Down Decades of Arterial Buildup

Nattokinase is a fibrinolytic enzyme extracted from natto, a traditional Japanese food with over 1,000 years of documented use.

Japan has the longest life expectancy on earth. Cardiovascular disease rates in natto-consuming regions are among the lowest ever recorded.

Nattokinase directly dissolves fibrin, the protein matrix that traps cholesterol inside artery walls and calcifies into plaque.


Circulene delivers 5,000 FU per capsule:

✅ Dissolves fibrin buildup in arterial walls
✅ Reduces plaque volume and arterial wall thickness
✅ Improves circulation and blood flow

    FAQ

    Frequently Asked Questions

    For most people, yes. Nattokinase is a natural enzyme and doesn't interfere with most common medications. Many people take it alongside statins, blood pressure medications, and other heart-related supplements without issue.

    However, if you're currently taking blood thinners (like Warfarin, Eliquis, or aspirin therapy), you should consult your doctor before adding Circulene to your routine, as nattokinase supports fibrin breakdown and may enhance their effects. If you have an upcoming surgery, discontinue use at least 2 weeks prior. If you have any concerns, we encourage you to speak with your doctor before starting.

    Many people notice improved circulation, lower blood pressure, and relief from symptoms like leg heaviness or swelling within the first few days to a couple of weeks. These early wins are signs your body is responding.

    For long-term cardiovascular benefits, it may take several weeks to a few months of consistent use. The studies showing plaque reduction were over a 6-12 month period. For this reason we offer generous quantity-based discounts for larger orders.

    Nattokinase has been consumed in Japan for over 1,000 years with an excellent safety record. Most people experience no side effects. However, if you're on blood thinners or have a bleeding disorder, do not take nattokinase without consulting your doctor first.

    Yes. Nattokinase is derived from nattō, a fermented soybean product rich in probiotics, vitamin K2, and nattokinase, which may support heart and bone health.

    It's generally well-tolerated and research suggests it may support cardiovascular health over time.

    For most healthy individuals, regularly eating natto as part of a balanced diet is safe and may even offer long-term health benefits. If you have any specific health concerns, it's always a good idea to check with your healthcare provider.
