Nattokinase

What is Nattokinase?

Nattokinase is a fibrinolytic enzyme extracted from the traditional Japanese fermented soybean product natt
4d. This type of soybean has been fermented using the bacterium Bacillus subtilis, resulting in a unique composition of nutrients and bioactive compounds.

How does it work in the body?

Nattokinase primarily works by breaking down fibrin, a protein that plays a central role in blood coagulation. When blood vessels are damaged, a chain of events is activated that leads to the formation of a blood clot to stop the bleeding. Nattokinase can help counteract this process by promoting fibrinolysis, which is the natural mechanism for dissolving blood clots.

Scientific benefits

Several studies have investigated the potential health benefits of nattokinase. Here are some of the most prominent findings:

• Improved circulation: Another study in the Journal of Nutritional Science and Vitaminology showed that nattokinase can improve blood circulation by reducing blood viscosity, making it easier for blood to flow through the vessels.
• Anticoagulant effect: Nattokinase has been shown to have an anticoagulant effect, meaning it can inhibit the formation of blood clots. A meta-analysis of several studies published in Thrombosis Research confirmed that nattokinase significantly reduced the incidence of venous thrombosis.

Dosage and recommendations

The recommended dose of nattokinase varies depending on the product and health condition. Generally, a dose between 100 600 mg per day is recommended. It is important to consult a doctor or other healthcare professional before starting nattokinase, especially if you have a history of cardiovascular diseases or are taking blood-thinning medications.

Best sources and forms

Nattokinase is primarily available in dietary supplements in the form of capsules or tablets. The quality of nattokinase supplements can vary, so it is important to choose products from reputable manufacturers that offer third-party testing for purity and efficacy.

Side effects and warnings

Although nattokinase is generally considered safe for most people, some individuals may experience mild side effects such as stomach discomfort or diarrhoea. Since nattokinase has anticoagulant properties, people taking blood-thinning medications such as warfarin or aspirin should be cautious and consult their doctor before starting nattokinase. Pregnant or breastfeeding women should also avoid nattokinase until more research is available.
