Nattovena® Supports

Healthy Circulation

How it Works

Fibrin is a protein that plays a major role in blood clotting and scar formation, making it an essential component of the healing process—and vital for maintaining your health and general well-being. However, fibrin overproduction and weak fibrin degradation have been a factor in many of today’s most common circulatory health concerns.

The Impact

Nattovena is one of the strongest nattokinase supplements available, period. It provides more than 4,000 fibrinolytic units (FUs) per capsule, which is twice the potency of ordinary nattokinase products.


The older we get, the more our fibrin levels fluctuate. Fibrin is an important protein involved in blood clotting.

Nattovena contains one of the highest fibrinolytic activities per capsule of any pure nattokinase supplements. This unmatched activity makes Nattovena a great choice for supporting normal blood viscosity and a healthy cardiovascular system.


A fibrinolytic enzyme that helps to maintain normal blood viscosity and support cardiovascular health. The enzyme was discovered while studying the fermented soy dish known as “natto.” A researcher was trying to uncover why certain foods had higher fibrinolytic activity than others. He came upon a Japanese fermented soybean food called natto that had large volumes of an enzyme that he coined “nattokinase”, based on where he discovered the enzyme. He later found that a microorganism that was used in the fermentation process was responsible for creating this enzyme. This same microorganism (Bacillus subtilis) is used today in the production of the enzyme.

Suggested Use

Directions: Take Nattovena with eight ounces of water on an empty stomach or as directed by your healthcare provider. Higher daily doses may be divided into two or three servings per day.

Maintenance: Two capsules per day. Increased Support: Four capsules per day. Therapeutic: Six capsules per day.

Warning: Do not take this product without the consent of your physician if you are currently taking blood-thinning medications or if you are pregnant or nursing.

What does Nattovena do?

Studies have demonstrated that nattokinase improves overall circulation, promotes healthy blood viscosity, and maintains healthy blood levels.

Why is fibrinolytic activity important?

Fibrin is a vital protein that forms in response to trauma, injury, or even in cases of autoimmune conditions. The body not only has the potential to overproduce fibrin in response to these instances, but can also produce fibrin when no trauma or injury has occurred, which can lead to a bevy of unwanted symptoms. Fibrinolytic activity is important because it’s the body’s natural way of breaking up excessive fibrin.

Is Nattovena safe?

Nattokinase is derived from natto, which has been a regular food staple in Asian cuisine for centuries. Although nattokinase has many benefits, studies have shown that it also does not have demonstrative side effects, and the ingredient is considered GRAS (generally recognized as safe) in the US.

Does Nattovena have value beyond just heart health?

Due to the vast array of unhealthy conditions that excessive fibrin can bring, Nattovena has far greater value than a simple cardiovascular support product. Many aspects of health, ranging from muscle recovery to immune health, can be related to fibrin and blood viscosity.

Is Nattovena safe to use in combination with prescription blood-thinning medications?

You should always check with your healthcare provider prior to taking any new dietary supplements in combination with a blood-thinning medication. Nattovena is not contraindicated with aspirin, natural supplements, or antihypertensive medications, although medical supervision when implementing any new supplement regimen is always recommended.

The Best Nattokinase

My doctor suggested I take Nattokinase enzymes to support my heart. He recommended Natto NSK, but I had to take 4 pills everyday. I found Nattovena pure Nattokinase was double the strength. Who would ever want to take baby aspirin again?
