Key ingredients

Nattokinase — 10,000 FU, CoQ10, Aged Garlic Extract, Turmeric, Pine Bark Extract, Bromelain

 

Why Put Them Together?

 

Think of cardiovascular health like keeping a highway running smoothly. Nattokinase is the specialized road crew supporting your body's natural fibrin-management process, while CoQ10, aged garlic, turmeric, pine bark, and bromelain provide complementary support for the heart, blood vessels, cellular energy, and overall cardiovascular system.

How it works

Think of healthy circulation like traffic moving smoothly down a highway. Your body naturally uses fibrin as part of its normal repair process—but afterward, it also needs systems that help manage and break down fibrin so everything keeps moving as it should.

Nattokinase is like adding extra support to the road crew responsible for that cleanup. Its enzyme activity has been studied for how it interacts with your body’s natural fibrinolytic process—the system involved in breaking down and remodeling fibrin.

How long before I see results?

The best time to start thinking about your cardiovascular health isn’t when something goes wrong. It’s while you still have the opportunity to be proactive about it. Nattokinase isn’t the kind of supplement you take today and dramatically “feel” tomorrow. There’s no buzz, rush, or overnight sensation—and we’re not going to invent one just to sell you a bottle. What you can feel is something far more important: the reassurance that you’re no longer putting your cardiovascular health on the back burner. Every morning you take Nattokinase, you’re making a small, intentional choice for the person you want to be 5, 10, and 20 years from now. This is for people who would rather take their cardiovascular wellness seriously today than wish they had paid more attention to it later.

Money Back Guarantee

30-day, no-questions-asked money-back guarantee. Full refund via a single email. You don't need to send the bottle back.

4 Benefits of Blyss Nattokinase

Supports Your Body’s Natural Fibrin Cleanup Process

This is what makes nattokinase different from your average heart-health supplement.

Your body produces fibrin, a tough, thread-like protein that plays an important role in the normal clotting and repair process. But your body also has a natural system—called fibrinolysis—responsible for breaking down and remodeling fibrin when appropriate.

Think of fibrin like scaffolding put up around a building during repairs. It serves an important purpose, but your body also needs a cleanup crew responsible for managing that scaffolding afterward.

Nattokinase is a proteolytic enzyme studied for its interaction with this natural fibrinolytic system. That's why supporting normal fibrinolytic processes is at the heart of what makes nattokinase so interesting for cardiovascular wellness

Supports Healthy Blood Flow & Circulation

Every part of your body depends on blood moving efficiently through an enormous network of blood vessels—from your heart all the way down to the smallest vessels in your hands and feet.

Think of your cardiovascular system like thousands of miles of roads carrying essential deliveries 24 hours a day. Supporting healthy circulation helps those highways do what they were designed to do: transport oxygen and nutrients throughout your body.

Nattokinase has attracted attention because of its fibrinolytic activity and the way it interacts with processes involved in normal blood flow and cardiovascular function.

But here's where we refuse to insult your intelligence: nattokinase isn't a magical “artery cleaner.” You may see brands make dramatic claims about “unclogging arteries” or “dissolving clots,” but that's not a promise responsible brands should make.

Blyss gives you the real benefit without needing the exaggerated story: high-activity nattokinase designed to support the processes your cardiovascular system already relies on.

Supports Healthy Blood Pressure Already Within a Normal Range

Your blood vessels aren't rigid pipes. They're living, responsive structures—and maintaining healthy cardiovascular function is an important part of keeping your heart working efficiently as you age.

Nattokinase has been studied in humans for its potential role in supporting healthy blood pressure and cardiovascular function. The effects observed in clinical research have generally been modest, which is exactly why we won't promise that a capsule will magically transform your numbers.

And that's an important distinction.

Nattokinase isn't medication, and it's not meant to replace medication. It's for people who understand that taking care of their cardiovascular health isn't about waiting for one miracle solution—it's about making smart choices consistently.

Adding nattokinase to that routine is simply another way of saying:

“I'm taking action now.”

Helps You Be Proactive About Long-Term Cardiovascular Wellness

This may be the most important benefit of all.

Most people don't suddenly wake up one morning and feel their cardiovascular system aging. That's precisely what makes it so easy to put heart health off until “someday.”

Nattokinase gives you an opportunity to make cardiovascular wellness part of what you do before it becomes something you wish you'd taken more seriously.

And Blyss takes that philosophy further. Instead of giving you nattokinase alone, we built our formula around 10,000 FU of nattokinase activity plus CoQ10, bromelain, turmeric, aged garlic extract, and pine bark extract for broader cardiovascular support.

We also won't tell you that 10,000 FU means “5X better results” simply because it's five times the activity of a 2,000-FU serving. FU measures enzyme activity; it doesn't guarantee proportionally greater clinical benefits. That's the kind of distinction we think someone taking a supplement every day deserves to know.

You may not feel your cardiovascular health changing from one day to the next. But every day you choose to support it is one more day you’re paying attention to something that’s far too important to ignore.

And years from now, you will be glad you started when you did.

Your Cardiovascular Health Deserves Proactive Attention Now, Even If You Feel Fine Today

Your Cardiovascular Health Deserves Proactive Attention Now, Even If You Feel Fine Today

It’s easy to take your cardiovascular health for granted when nothing feels wrong.

You wake up, go to work, spend time with your family, and live your life without giving much thought to what your heart and blood vessels are doing behind the scenes.

And that’s exactly why cardiovascular wellness is so easy to put off.

You don’t need to wait until something feels wrong to start paying attention. Just like you maintain your car before the warning lights come on, taking care of your cardiovascular health is about supporting the system you depend on every single day—while it’s still quietly doing its job.

Because as the years pass, priorities change. You start thinking less about how you feel today and more about staying healthy, active, and independent for all the tomorrows that matter.

That’s where being proactive comes in.

Not because you should live worried about what might happen—but because there’s something reassuring about knowing you’re no longer leaving something this important on the back burner.

You may feel perfectly fine today. That’s not a reason to wait. It’s one of the best reasons to start.

The Most Credible Nattokinase Story May Be the One That Tells You What It Can’t Promise

  • The Research

  • What’s Inside

  • Why It Works

Blyss Nattokinase: A Transparent Daily Wellness Routine

Nattokinase has earned attention for a reason: this remarkable enzyme has demonstrated fibrinolytic activity and has been studied for its potential role in supporting healthy circulation and cardiovascular function. But while other brands may turn that science into claims about “dissolving clots” or “clearing arteries,” we won’t sell you a promise the research hasn’t proven. Instead, we focus on what makes nattokinase so compelling: its ability to support the body’s normal fibrinolytic processes and a healthy cardiovascular system.

 Think of fibrinolysis like your body’s natural cleanup crew—helping manage and break down fibrin as part of the normal process that keeps your circulatory system functioning as it should. Human research has also found promising signals around blood pressure. That’s why we give you the science without turning “promising” into “proven.” Real cardiovascular support, a fascinating research-backed mechanism, and complete transparency about what we know—and what we don’t.

✔ Designed for everyday use
✔ 10,000 FU per serving
✔ Simple three-capsule daily routine

The Complex

Most nattokinase supplements stop at the enzyme. We built an entire cardiovascular support complex around it.  At the center is 10,000 FU of nattokinase. FU stands for Fibrinolytic Units—a measure of an enzyme’s activity, not simply how much it weighs. Think of it like horsepower: milligrams tell you how much enzyme is there; FU tells you how much measured enzymatic activity it has. Nattokinase is known for its fibrinolytic activity—supporting the body’s natural processes for managing fibrin and maintaining healthy circulation.

 But cardiovascular health involves more than one pathway, which is why we didn't stop at nattokinase. Our formula combines it with CoQ10, Bromelain, Turmeric, Aged Garlic Extract, and Pine Bark Extract—ingredients selected to complement a comprehensive heart and circulation-focused daily routine. The result isn't just another bottle of nattokinase competing on a label. It's a multi-ingredient cardiovascular complex built around 10,000 FU of measured nattokinase activity.

✔ 10,000 FU per serving
✔ No fillers or unnecessary additives
✔ Third-party tested for purity and potency

Made Differently

Think of healthy circulation like traffic moving smoothly down a highway. Your body naturally uses fibrin as part of its normal repair process—but afterward, it also needs systems that help manage and break down fibrin so everything keeps moving as it should. Nattokinase is like adding extra support to the road crew responsible for that cleanup. Its enzyme activity has been studied for how it interacts with your body’s natural fibrinolytic process—the system involved in breaking down and remodeling fibrin. And with nattokinase, what matters isn't simply how much enzyme powder you have—it's how active that enzyme is. 

That's why Blyss provides 10,000 FU of nattokinase activity. FU (Fibrinolytic Units) measures activity, giving you a more meaningful way to understand the enzyme than milligrams alone. But we didn't build Blyss around one ingredient alone. We pair nattokinase with CoQ10, bromelain, turmeric, aged garlic extract, and pine bark extract to create a broader cardiovascular-support formula with complementary ingredients. The goal is simple: support the natural processes that help keep your cardiovascular system working the way it should—without pretending nattokinase is a miracle pill. 10,000 FU. Six complementary ingredients. No exaggerated promises. That's the Blyss difference.

We're serious about what goes into your body, ask away

Transparency matters when it comes to daily supplements. Below you'll find answers to the most common questions about Blyss Nattokinase — how it works, what to expect, and how we ensure quality, purity, and consistency in every capsule.

Is 10,000 FU actually better than 2,000 or 4,000 FU?

FU stands for Fibrinolytic Units—the measurement used to describe nattokinase’s enzyme activity. Think of it like horsepower: 2,000, 4,000 and 10,000 FU aren't simply different amounts of powder—they represent different levels of measured activity.

That's one reason Blyss® was built around a 10,000 FU serving rather than the lower-activity servings commonly found in the category. You get 5X the measured activity of a 2,000 FU serving and 2.5X that of a 4,000 FU serving.

What can I expect when adding nattokinase to my daily routine?

Don’t expect a sudden rush or dramatic overnight sensation. Nattokinase isn’t that kind of supplement—and you don’t need to “feel it working” for it to become a meaningful part of your cardiovascular wellness routine.

What you may notice first is something different: the confidence that comes from finally being proactive about something that’s easy to ignore when you feel perfectly fine.

Why nattokinase instead of just eating natto?

Natto is where nattokinase comes from—but taking nattokinase as a supplement gives you something a serving of food can’t easily promise: a clearly measured amount of enzyme activity.

Traditional natto is made by fermenting soybeans with Bacillus subtilis natto. While it naturally contains nattokinase, the amount of enzyme activity you get from food can vary from serving to serving.

With Blyss®, you know exactly what you’re taking: 10,000 FU of nattokinase activity in every full serving. No guessing how much natto you need to eat or how much activity it provides.

How should I take Blyss Nattokinase?

Take 3 capsules daily, which provides the complete 10,000 FU serving of nattokinase along with the rest of the Blyss® cardiovascular-support formula.

For simplicity, make it part of a routine you already have—such as taking your capsules with a meal each day. Consistency is the goal. Blyss® is designed to make proactive cardiovascular support an easy habit you can continue every day.

If you take prescription medications—particularly anticoagulants, antiplatelet medications or daily aspirin—or have a bleeding disorder or upcoming surgery, speak with your healthcare professional before using nattokinase.
