Nattokinase has been shown to support healthy blood pressure by improving circulation and reducing blood clot risks naturally.
Understanding Nattokinase and Its Origins
Nattokinase is an enzyme extracted from natto, a traditional Japanese food made by fermenting soybeans with the bacterium Bacillus subtilis. Natto has been consumed for centuries in Japan, prized for its unique texture and health benefits. Nattokinase itself was discovered in the 1980s and quickly gained attention due to its powerful fibrinolytic properties—meaning it can break down fibrin, a protein involved in blood clot formation.
This enzyme’s ability to dissolve fibrin suggests it might improve blood flow by preventing clots and reducing arterial stiffness. Since high blood pressure is often linked with poor circulation and vascular resistance, nattokinase has become a popular natural supplement for cardiovascular health.
How Blood Pressure Works and Why It Matters
Blood pressure measures the force of blood pushing against artery walls as the heart pumps. It’s recorded as two numbers: systolic (pressure during heartbeats) over diastolic (pressure between beats). Normal blood pressure is generally around 120/80 mm Hg.
High blood pressure, or hypertension, occurs when this force stays elevated over time. This condition strains arteries and organs like the heart, kidneys, and brain. Persistent hypertension raises risks of heart attacks, strokes, and kidney disease.
Many factors contribute to high blood pressure: genetics, diet high in salt or fat, obesity, stress, inactivity, smoking, and aging. Treatments usually include lifestyle changes and medications to relax vessels or reduce fluid volume.
Does Nattokinase Lower Blood Pressure? The Science Behind It
Research on nattokinase indicates it can support healthy blood pressure through several mechanisms:
- Fibrinolytic Activity: By breaking down fibrin clots, nattokinase helps maintain smoother blood flow, which can reduce vascular resistance.
- Blood Thinning Effects: It may act similarly to mild anticoagulants by preventing excessive clotting without harsh side effects.
- Improved Circulation: Better flow means less strain on arterial walls and a potential drop in systolic pressure.
Several clinical studies have explored nattokinase’s impact on hypertension:
- A 2008 study published in Hypertension Research found that participants taking nattokinase daily for eight weeks experienced significant reductions in both systolic and diastolic pressures compared to placebo.
- Another trial showed nattokinase reduced plasma levels of von Willebrand factor—a protein linked with clotting—and improved endothelial function (the lining of blood vessels), which plays a key role in regulating blood pressure.
- Animal studies also support these findings by demonstrating vasodilation effects—widening of blood vessels—which naturally lowers pressure.
Though promising, these studies often involve small sample sizes or short durations. More extensive research is needed to confirm long-term benefits conclusively.
Nattokinase vs. Conventional Blood Pressure Medications
Unlike prescription drugs such as ACE inhibitors or beta-blockers that directly alter heart rate or fluid balance, nattokinase works more subtly by enhancing natural processes like clot breakdown and vessel flexibility.
This difference means nattokinase may be safer for some people who prefer natural supplements or want fewer side effects. However, it should never replace prescribed medication without consulting a healthcare provider.
The Role of Nattokinase in Cardiovascular Health Beyond Blood Pressure
Nattokinase doesn’t just influence blood pressure; it also supports overall cardiovascular function:
- Prevention of Thrombosis: By dissolving fibrin clots, it reduces risks of deep vein thrombosis (DVT) and stroke.
- Lipid Profile Improvement: Some studies suggest nattokinase may help lower LDL (“bad”) cholesterol while raising HDL (“good”) cholesterol.
- Anti-inflammatory Effects: Chronic inflammation contributes to arterial damage; nattokinase may help reduce this inflammation.
These combined effects contribute to healthier arteries that are more elastic and less prone to blockages—both crucial factors for maintaining normal blood pressure levels.
Table: Comparison of Nattokinase Effects vs. Common Blood Pressure Medications
| Effect | Nattokinase | Common Medications (e.g., ACE inhibitors) |
|---|---|---|
| Blood Pressure Reduction | Mild to moderate via improved circulation | Moderate to strong via vessel dilation or fluid control |
| Blood Thinning | Mild fibrinolytic activity reducing clots | No direct effect; separate anticoagulants needed if required |
| Side Effects Risk | Low; mostly mild digestive upset possible | Varies; can include cough, dizziness, electrolyte imbalance |
Dosing Guidelines and Safety Considerations for Nattokinase
Typical dosages used in clinical trials range from 100 mg to 200 mg per day of nattokinase enzyme activity (measured in fibrinolytic units). Supplements often recommend taking doses once or twice daily on an empty stomach for optimal absorption.
While generally safe for most healthy adults, some precautions exist:
- Bleeding Risk: Because it affects clotting mechanisms, nattokinase could increase bleeding risk if combined with other anticoagulants like warfarin or aspirin.
- Surgery Precautions: Avoid use at least two weeks before any surgical procedure due to potential bleeding complications.
- Pregnancy & Breastfeeding: Not enough safety data available; best avoided during these times.
- Allergic Reactions: Rare but possible soy allergies should be considered since natto is soy-based.
Always consult a healthcare professional before starting nattokinase supplements—especially if you have existing medical conditions or take other medications.

Frequently Asked Questions
Does Nattokinase Lower Blood Pressure Effectively?
Research suggests that nattokinase can support healthy blood pressure by improving circulation and reducing blood clot risks. Its fibrinolytic activity helps break down fibrin, promoting smoother blood flow and potentially lowering vascular resistance.
How Does Nattokinase Lower Blood Pressure?
Nattokinase lowers blood pressure by breaking down fibrin clots and acting as a mild blood thinner. This improves circulation, reduces arterial stiffness, and lessens the strain on artery walls, which can contribute to lower systolic and diastolic pressure.
Is There Scientific Evidence That Nattokinase Lowers Blood Pressure?
Clinical studies have shown that taking nattokinase daily can lead to significant reductions in both systolic and diastolic blood pressure. For example, a 2008 study found notable improvements after eight weeks of supplementation.
Can Nattokinase Replace Blood Pressure Medications?
While nattokinase shows promise in supporting healthy blood pressure, it should not replace prescribed medications without consulting a healthcare provider. It may be used as a complementary approach alongside lifestyle changes and medical treatment.
Are There Any Risks in Using Nattokinase to Lower Blood Pressure?
Nattokinase acts as a natural blood thinner, so it may increase bleeding risk, especially if combined with other anticoagulants. It’s important to speak with a healthcare professional before starting nattokinase supplements for blood pressure management.
The Bottom Line – Does Nattokinase Lower Blood Pressure?
The evidence points toward nattokinase being a helpful natural agent for supporting healthy blood pressure through improved circulation and clot prevention. Its unique enzymatic action gently reduces vascular resistance without harsh side effects typical of some medications.
Still, nattokinase isn’t a magic bullet. It works best alongside lifestyle changes like diet improvements, regular exercise, stress management, and maintaining a healthy weight. Anyone considering nattokinase should discuss it with their doctor first—especially if they’re already on prescription drugs or have bleeding disorders.
In summary:
- Nattokinase shows promise for lowering mild to moderate high blood pressure.
- Its benefits stem from fibrinolytic activity improving vessel health.
- Caution is necessary regarding bleeding risks when combined with other anticoagulants.
- A holistic approach yields the best results for cardiovascular wellness.
If you’re curious about natural ways to enhance your heart health beyond conventional options, exploring nattokinase under medical guidance might be worth considering. Its long history rooted in traditional Japanese cuisine combined with modern science creates an intriguing option on the path toward balanced blood pressure.
