Frequently Asked Questions
Q
What is the difference between natto and nattokinase?
A
Natto is a food made by fermenting boiled soybeans with natto bacteria. Nattokinase refers to the enzyme produced by natto bacteria during this fermentation process. When taken as a supplement, it is less affected by stomach acid, allowing for stable absorption.
Q
What effects does nattokinase have?
A
Nattokinase not only directly dissolves blood clots but also activates fibrinolytic enzymes in the body such as plasmin and urokinase. It has also been confirmed to reduce a substance called PAI-1 in the body. Blood flow improvement, blood pressure reduction, and platelet aggregation inhibition effects have also been reported. (Source: Japan Nattokinase Association)
Q
When is the best time to take it for effectiveness?
A
Blood clots tend to form when the body is dehydrated or blood flow is compressed for long periods, so it is said to be most effective to take this from after dinner until before bedtime. It is also recommended before long flights. (Source: Japan Nattokinase Association)
Q
What is the recommended daily intake?
A
The Japan Nattokinase Association recommends a daily intake of 2000 FU. This product contains 4000 FU in 2 capsules, providing twice the recommended activity. Taking more does not increase the effect, so please follow the daily recommended amount. (Source: Japan Nattokinase Association)
Q
I am taking warfarin; is it safe to take this together?
A
The nattokinase in this product only works to dissolve blood clots and does not cause bleeding to continue. Clinical trials have confirmed the safety of combining nattokinase with warfarin. However, if you are taking medication, please consult a doctor or pharmacist before use as a precaution. (Source: Japan Nattokinase Association)
