Are there any other contraindications for consuming natto enzymes?

Dr. Huang Shenggang reply Pharmacology


Natto is rich in vitamin K, which is related to the promotion of blood coagulation (hemostatic effect).
For patients taking the anticoagulant Warfarin, it can counteract the effects of the anticoagulant.

When considering the consumption of natto enzyme, also known as nattokinase, there are several important precautions and potential contraindications to keep in mind. Nattokinase is an enzyme extracted from natto, a traditional Japanese food made from fermented soybeans. It is often touted for its potential health benefits, particularly in cardiovascular health, due to its ability to dissolve fibrin, a protein involved in blood clotting.

1. Blood Thinning Effects: One of the primary concerns with nattokinase is its blood-thinning properties. Individuals who are taking anticoagulant medications, such as warfarin, heparin, or aspirin, should exercise caution when consuming nattokinase. The combination of these medications with nattokinase may increase the risk of bleeding. It is essential to consult a healthcare provider before starting nattokinase if you are on any blood-thinning medications.

2. Surgery: If you are scheduled for surgery, it is advisable to discontinue the use of nattokinase at least two weeks prior to the procedure. This precaution is due to its potential to interfere with blood clotting, which could lead to excessive bleeding during and after surgery.

3. Pregnancy and Breastfeeding: There is limited research on the safety of nattokinase during pregnancy and breastfeeding. Therefore, it is recommended that pregnant or nursing women avoid nattokinase unless specifically advised by a healthcare professional.

4. Allergic Reactions: Individuals with a known allergy to soy products should avoid nattokinase, as it is derived from fermented soybeans. Allergic reactions can range from mild symptoms, such as hives or itching, to severe reactions, including anaphylaxis.

5. Underlying Health Conditions: People with certain health conditions, particularly those related to blood disorders or clotting issues, should consult their healthcare provider before taking nattokinase. This includes individuals with hemophilia or those who have a history of stroke or other cardiovascular issues.

6. Drug Interactions: Nattokinase may interact with other medications, particularly those that affect blood clotting. It is crucial to inform your healthcare provider about all medications and supplements you are taking to avoid potential interactions.

7. Dosage and Quality: If you decide to take nattokinase, ensure that you are using a high-quality supplement from a reputable source. The dosage can vary, and it is essential to follow the recommended guidelines or your healthcare provider's advice.

8. Monitoring: If you are taking nattokinase, it may be beneficial to have regular check-ups with your healthcare provider to monitor your blood levels and overall health, especially if you are on anticoagulant therapy.

In summary, while nattokinase may offer health benefits, particularly for cardiovascular health, it is essential to approach its use with caution. Always consult with a healthcare professional before starting any new supplement, especially if you have underlying health conditions or are taking other medications. By doing so, you can ensure that you are making informed decisions about your health and minimizing any potential risks associated with the use of nattokinase.
