Nattokinase

Nattokinase is an enzyme that is extracted from natto, a traditional Japanese food made from soybeans that have been fermented with the bacterium Bacillus subtilis var. natto. Nattokinase is known for its potential health benefits, particularly in the areas of cardiovascular health and blood circulation. It has been studied for its ability to dissolve blood clots and improve blood flow, which makes it of interest in the prevention and treatment of conditions such as deep vein thrombosis, atherosclerosis, and hypertension.

History

The discovery of nattokinase is attributed to Dr. Hiroyuki Sumi, who in the 1980s was conducting research at the University of Chicago. He found that a part of the natto exhibited strong fibrinolytic activity, which means it could dissolve blood clots. This component was later identified as nattokinase. Since then, nattokinase has been the subject of numerous scientific and clinical studies to explore its health benefits.

Production

Nattokinase is produced through a fermentation process using Bacillus subtilis var. natto. The soybeans are fermented, and then the nattokinase is extracted and purified. It is available in various forms, including capsules, tablets, and powders, as a dietary supplement.

Mechanism of Action

Nattokinase works by directly degrading fibrin, a protein involved in blood clot formation, and by enhancing the body's natural ability to dissolve blood clots. It also has the ability to indirectly influence various blood-clotting factors, contributing to its anticoagulant and thrombolytic effects.

Health Benefits

Research suggests that nattokinase may offer several health benefits, including:

• Reducing the risk of cardiovascular diseases by improving blood flow and reducing blood pressure.
• Preventing and treating blood clots, which can reduce the risk of stroke and deep vein thrombosis.
• Potentially improving bone health by influencing bone metabolic markers.

Safety and Side Effects

While nattokinase is generally considered safe when consumed in food form as natto, the safety of nattokinase supplements has not been established for pregnant women, breastfeeding mothers, and children. People on blood-thinning medication or those with bleeding disorders should exercise caution and consult a healthcare provider before taking nattokinase supplements due to the risk of excessive bleeding.

Conclusion

Nattokinase represents a promising natural remedy with potential cardiovascular benefits. However, further research is needed to fully understand its mechanisms, efficacy, and safety profile. As with any supplement, it is important to consult with a healthcare professional before starting nattokinase, especially for individuals with pre-existing health conditions or those taking medication.
