Nattokinase: The Japanese Enzyme with a Cardiovascular Pedigree

When we consider the pillars of long-term wellness, few things are as foundational as a healthy circulatory system. For decades, researchers have looked to the traditional Japanese diet, rich in fermented foods, for clues to its associated health benefits. One particular discovery from the 1980s has since captured the attention of nutritional science: nattokinase. This enzyme, extracted from the fermented soybean dish natto, is now studied for its unique properties that may support cardiovascular and circulatory wellness.

Nattokinase is a naturally occurring enzyme produced during the fermentation of soybeans by the bacterium Bacillus subtilis. Since then, it has been the subject of numerous studies exploring its potential role in circulatory health. The enzyme's activity is measured in Fibrinolytic Units (FU), a standardised way to quantify its potency, with typical supplements offering between 100 and 2000 FU per serving.

Research suggests that nattokinase may support the body's natural mechanisms for maintaining healthy blood flow. It is important to note that these effects are associated with general circulatory wellness, not with the treatment of any specific condition.

The traditional Japanese diet is rich in whole foods, with natto being a particularly notable component. Natto is made by steaming soybeans and then fermenting them with Bacillus subtilis. This process not only produces nattokinase but also enhances the bioavailability of other nutrients, such as vitamin K2. While it is difficult to isolate the effects of any single food, the presence of nattokinase in this dietary pattern provides a compelling rationale for its study. For those who do not regularly consume natto, supplementation offers a convenient way to incorporate this enzyme into a wellness routine.

While nattokinase is generally well-tolerated, it is not suitable for everyone. Because of its fibrinolytic activity, it may interact with anticoagulant medications (commonly known as blood thinners) such as warfarin, apixaban, or rivaroxaban. Taking nattokinase alongside these drugs could theoretically increase the risk of bleeding. Our Nattokinase Multi label says: do not take this product while using blood pressure or blood thinning medication, or if you are pregnant or nursing. Persons taking medication should only consume this product under medical supervision.

When selecting a nattokinase supplement, look for products that clearly state the Fibrinolytic Units (FU) per serving. A typical dose ranges from 100 to 2000 FU daily, though optimal amounts vary based on individual needs and product formulation. As a general rule, it is wise to avoid any product that makes exaggerated claims about treating or curing disease. Instead, focus on brands that present their product as a support for normal circulatory function, in line with the available research.

Nattokinase represents a fascinating intersection of traditional food culture and modern nutritional science. While it is not a replacement for medical treatment, for many people, it may serve as a valuable addition to a lifestyle that already includes a balanced diet and regular physical activity. As always, it is wise to discuss any new supplement with a healthcare professional, especially if you have underlying health conditions or are taking medication.
