What Is Nattokinase?

Nattokinase (NK), also known as subtilisin, is an enzyme extracted from natto, a fermented soybean made by combining boiled soybeans with specific bacteria. It is well known for its potential health benefits, especially in promoting cardiovascular health. The enzyme is thought to help break down fibrin, a protein involved in blood clotting, which may improve blood flow and reduce the risk of conditions such as deep vein thrombosis (DVT) or stroke.

Some studies suggest that nattokinase may help break down blood clots and improve blood circulation, acting as a natural anticoagulant. However, despite its promising potential, more research is needed to fully understand its efficacy and safety, especially for people with bleeding disorders or those taking blood-thinning medications.

Nattokinase is typically sold as a dietary supplement in capsule form and is often marketed for its potential to support heart health, lower blood pressure, and improve blood circulation.

Function of Kinase

Kinase is an enzyme that catalyzes the transfer of phosphate groups from high-energy molecules such as ATP (adenosine triphosphate) to specific substrates, usually proteins. This process is called phosphorylation, and it plays a vital role in regulating various cellular activities. The functions of kinases can be divided into the following key roles:

  • Preventing and dissolving blood clots, protecting the cardiovascular system, and avoiding myocardial infarction and stroke.
  • Lowering blood pressure, inhibiting enzymes that cause high blood pressure.
  • Lowering cholesterol, effectively reducing total cholesterol and bad cholesterol.
  • Preventing and treating osteoporosis and diabetes.

Application of Nattokinase

  • Functional food. Promotes primary proteolysis in cheese as an exogenous proteolytic enzyme. This process increases the content of most free amino acids that can be used as substrates for many catabolic reactions to improve the flavor of the cheese.
  • Health care products. Effectively remove blood clots in the human body, and are also effective in preventing high blood pressure, aging, stroke, muscle spasm, and cardiovascular and cerebrovascular injuries.

Dosage

The recommended dose of nattokinase is typically 2,000 mg per day. However, some people may take up to 5,000 mg per day depending on their health needs or as directed by their doctor. Always follow the dosing instructions on the supplement label or as directed by your healthcare provider. To ensure safety and effectiveness, do not exceed the recommended dose without consulting your doctor, especially if you are taking blood-thinning medication or have any underlying health conditions.

For optimal absorption, nattokinase should be taken with a glass of water, preferably on an empty stomach, unless otherwise directed.
