The Origin of Nattokinase
Nattokinase is an enzyme that has its roots in the traditional Japanese dish known as natto. Natto is made by fermenting soybeans using a specific bacterium called Bacillus subtilis var. natto. The fermentation process results in a sticky, pungent food that is rich in protein and other nutrients. Nattokinase was first identified in the early 1980s by Dr. Hiroyuki Sumi, who was studying the effects of various natural foods on blood clotting. He discovered that natto had a significant fibrinolytic activity, meaning it could break down fibrin, a protein involved in blood clot formation.
The discovery of nattokinase marked a significant milestone in nutritional science, as it offered a natural alternative to synthetic blood thinners, which are commonly used to prevent and treat cardiovascular diseases. Today, nattokinase is extracted from natto and is available in supplement form, making it accessible to people worldwide who may not have access to the traditional dish.
In Japan, natto has been consumed for over a thousand years and is often praised for its health benefits. It is known for its high content of vitamins, especially vitamin K2, which is essential for bone health and cardiovascular function. The fermentation process not only enhances the digestibility of soybeans but also creates bioactive compounds like nattokinase that contribute to its health-promoting properties.
Composition and Properties of Nattokinase
Nattokinase is a serine protease enzyme, which means it can break down proteins by cleaving peptide bonds. It is composed of a single polypeptide chain with a molecular weight of approximately 28 kDa. The enzyme is characterized by its ability to degrade fibrin, a fibrous protein that forms the structural framework of blood clots. This property is what makes nattokinase particularly interesting for its potential cardiovascular benefits.
In addition to its fibrinolytic activity, nattokinase has been found to exhibit other biological activities that contribute to its therapeutic potential. Studies have shown that it may help reduce blood pressure, improve circulation, and enhance the body's natural ability to break down blood clots. These properties are attributed to its ability to modulate various enzymes and pathways involved in hemostasis and thrombosis.
It's important to note that the activity of nattokinase can vary depending on the source and method of extraction. Therefore, when choosing a nattokinase supplement, it's crucial to consider factors such as enzyme activity, purity, and the presence of any additives or preservatives. High-quality supplements should provide standardized enzyme activity, typically measured in fibrinolytic units (FU), to ensure consistent efficacy.
How Nattokinase Works
The primary mechanism of action of nattokinase is its ability to degrade fibrin, a key component of blood clots. Fibrin is formed during the blood coagulation process when thrombin, an enzyme, converts fibrinogen, a soluble plasma protein, into insoluble fibrin strands. These strands then form a mesh that traps blood cells, resulting in the formation of a clot. Nattokinase can cleave the fibrin strands, promoting the dissolution of the clot and improving blood flow.
Beyond its fibrinolytic activity, nattokinase influences other components of the coagulation cascade. It has been shown to enhance the production of plasmin, an enzyme that plays a crucial role in fibrinolysis. By increasing plasmin levels, nattokinase further supports the breakdown of fibrin and helps maintain a balance between clot formation and dissolution.
Another interesting aspect of nattokinase is its potential to lower blood pressure. Research suggests that it may inhibit angiotensin-converting enzyme (ACE), which is involved in regulating blood pressure. By blocking ACE, nattokinase may contribute to vasodilation, resulting in improved blood flow and reduced blood pressure levels.
