How long can I take nattokinase?

What is Nattokinase?

Nattokinase is a fibrinolytic enzyme that has been found to possess potent anticoagulant properties. It is able to break down fibrin, a protein involved in blood clot formation, and prevent the formation of potentially dangerous blood clots. This enzyme is produced by Bacillus subtilis, a bacterium that ferments soybeans during the production of Natto.

The Health Benefits of Nattokinase

Nattokinase has been extensively studied for its potential health benefits, especially in relation to cardiovascular health. Research suggests that nattokinase may help improve blood circulation, reduce the risk of blood clot formation, and lower blood pressure levels. These properties make it a promising natural alternative for managing and preventing various cardiovascular conditions, such as heart attacks, strokes, and deep vein thrombosis.

Additionally, nattokinase has also been found to possess anti-inflammatory and antioxidant properties. This can contribute to reducing inflammation in the body, supporting joint health, and potentially providing protection against chronic diseases.

Appropriate Duration of Nattokinase Supplementation

The appropriate duration of taking nattokinase varies depending on individual health conditions and goals. It is always recommended to consult with a healthcare professional before starting any supplementation to determine the most suitable dosage and duration for your specific needs.

Generally, nattokinase is taken orally as a dietary supplement. The recommended dosage typically ranges from 100 to 2000 fibrinolytic units (FU) per day, divided into multiple doses. For individuals who are new to nattokinase supplementation, it is best to start with a lower dosage and gradually increase it as necessary under medical guidance.

While nattokinase is considered safe for consumption by most individuals, it is important to remember that it has anticoagulant properties. This means that it can potentially interact with certain medications or medical conditions that affect blood clotting. Therefore, it is crucial to inform your healthcare provider about any existing medical conditions or ongoing medications before incorporating nattokinase into your daily regimen.


Nattokinase is a powerful enzyme that offers potential health benefits, especially in supporting cardiovascular health. When taken appropriately under medical guidance, it may help improve blood circulation, reduce the risk of blood clot formation, and support overall cardiovascular well-being. However, it is crucial to consult with a healthcare professional to determine the correct dosage and duration based on individual health conditions and goals. By doing so, you can ensure the safe and effective use of nattokinase to optimize your health and well-being.

Frequently Asked Questions

How long can I take nattokinase?

The duration of nattokinase supplementation will depend on various factors such as the reason for taking it, individual health conditions, and advice from a healthcare professional. It is best to consult with a healthcare provider to determine the appropriate length of time for taking nattokinase.

Can I take nattokinase indefinitely?

While there is no specific evidence suggesting any harm in long-term use of nattokinase, it is always recommended to follow the guidelines provided by healthcare professionals. It is important to regularly evaluate the benefits and potential risks associated with any dietary supplement, including nattokinase.

Are there any known side effects from taking nattokinase?

Most people tolerate nattokinase well, but like any supplement, it may cause side effects in some individuals. Common side effects may include mild gastrointestinal discomfort, allergic reactions, or an increased risk of bleeding. If any concerning side effects occur, it is essential to seek medical attention.

Can I take nattokinase if I have a bleeding disorder?

Individuals with bleeding disorders or those taking anticoagulant medications should exercise caution when considering nattokinase supplementation. Nattokinase may have anticoagulant properties, and combining it with existing blood-thinning medications could increase the risk of bleeding. Consultation with a healthcare professional is necessary before starting nattokinase in such cases.

Can I take nattokinase with other medications?

It is crucial to consult with a healthcare provider before combining nattokinase with any other medications. Nattokinase may interact with certain drugs, including anticoagulants, antiplatelet medications, or supplements that have blood-thinning properties. A healthcare provider can evaluate potential interactions and provide personalized recommendations.
