Lumbrokinase vs Nattokinase

With cardiovascular health receiving increasing attention, lumbrokinase and nattokinase, as two core functional ingredients, are becoming a focus for brands and formulators. Although both are thrombolytic enzymes, they differ fundamentally in their source, enzyme composition, mechanism of action, and application. For B2B businesses, a precise understanding of these similarities and differences is crucial. Healthkintai^® is a manufacturer and supplier of nattokinase. We offer various specifications of nattokinase powder. Contact us at info@kintaibio.com.

Lumbrokinase is a serine protease complex extracted and purified from earthworms using modern biotechnology. As a bioactive raw material that has attracted much attention in recent years, its main functions lie in thrombolysis and improving circulation: lumbrokinase can directly degrade fibrin, the thrombus backbone, while simultaneously activating the body's own plasminogen, exerting a dual thrombolytic effect and providing auxiliary improvement for thrombotic diseases such as atherosclerosis, cerebral infarction, and coronary heart disease.

In addition, it can inhibit platelet adhesion and aggregation, reduce blood viscosity, improve microcirculation, and studies have shown its potential in degrading amyloid protein, providing a new direction for the intervention of neurodegenerative diseases. Based on its clear mechanism of action and strong bioactivity, lumbrokinase is widely used in the development of raw materials for functional foods, health foods, and pharmaceuticals.

Nattokinase is a serine protease extracted from natto, a traditional Japanese food. Produced by the fermentation of soybeans by Bacillus subtilis, it has become a star functional ingredient in the cardiovascular health field due to its powerful thrombolytic activity.In terms of efficacy, nattokinase exerts its thrombolytic effect through a dual mechanism: on the one hand, it directly degrades fibrin, the main backbone of thrombi; on the other hand, it effectively activates the body's own plasminogen, enhancing endogenous thrombolytic capacity. Compared with many thrombolytic substances, nattokinase has a smaller molecular weight, higher oral absorption and utilization rate, and a longer duration of action. Therefore, it is widely used in the development of functional foods, dietary supplements, and health products, making it suitable for long-term daily cardiovascular health maintenance.

Nattokinase exerts its thrombolytic effect primarily through a dual pathway. Firstly, it possesses direct fibrinolytic activity, capable of degrading fibrin, which constitutes the thrombus skeleton, into soluble products, achieving rapid thrombolysis. Secondly, nattokinase can activate plasminogen in the body into plasmin, enhancing the body's endogenous thrombolytic ability. Simultaneously, it can degrade plasminogen activator inhibitor (PAI-1), relieving its inhibition of the fibrinolytic system and further amplifying the thrombolytic effect. Furthermore, nattokinase can inhibit platelet aggregation, reduce blood viscosity, and exert an auxiliary antihypertensive effect by regulating angiotensin-converting enzyme (ACE) activity. Its small molecular weight, high oral absorption rate, and long duration of action make it suitable for daily cardiovascular health maintenance.

Lumbrokinase

Lumbrokinase, as an enzyme complex, exhibits a more diverse and synergistic mechanism of action. Firstly, lumbrokinase can directly degrade fibrin, and due to its multiple isoenzymes, it demonstrates high efficiency in fibrin recognition and cleavage, resulting in significant thrombolytic activity. Secondly, it enhances the body's own thrombolytic capacity by activating plasminogen to plasmin and promoting the release of tissue-type plasminogen activator (t-PA). Furthermore, lumbrokinase can inhibit platelet adhesion and aggregation, reducing the risk of thrombosis; it can also degrade inhibitory factors such as α2-antiplasmin in the blood, reducing obstacles to the thrombolytic process. This multi-target synergistic mechanism makes lumbrokinase highly valuable in acute thrombotic intervention and the improvement of complex microcirculatory disorders.

In a comparison between nattokinase and lumbrokinase, nattokinase demonstrates comprehensive advantages in multiple dimensions, making it more suitable for daily health management.Nattokinase has a smaller molecular weight, resulting in higher oral absorption and better stability in the gastrointestinal environment, ensuring bioavailability. It possesses a dual thrombolytic mechanism, directly degrading fibrin and activating endogenous plasminogen activator inhibitor (PAI-1), thus relieving thrombolytic inhibition at its source, resulting in a more complete pathway of action.Furthermore, nattokinase also has multiple functions including assisting in lowering blood pressure, inhibiting platelet aggregation, and improving blood viscosity. It has richer clinical research and population application data, higher consumer awareness, and lower product education costs.

In contrast, while lumbrokinase exhibits stronger direct thrombolytic activity, as an enzyme complex, its composition is more complex, making stability control more difficult. Moreover, its origin from earthworms presents raw material acceptance issues in some markets. Therefore, for product development focused on daily cardiovascular health maintenance, long-term safety, and market universality, nattokinase is often a better choice.

Lumbrokinase is mainly divided into two categories on the market: pharmaceuticals and dietary supplements. In the pharmaceutical category, lumbrokinase is approved as a prescription drug, with common dosage forms including enteric-coated capsules and enteric-coated tablets, typically in strengths of 300,000 or 600,000 units. This medication must be used under the guidance of a doctor and is suitable for patients with ischemic cerebrovascular disease exhibiting elevated fibrinogen and platelet aggregation rates; it must be taken half an hour before meals. In the dietary supplement category, lumbrokinase is primarily available in capsule form and sold for daily health maintenance.

Nattokinase products have more diverse forms and are mainly distributed as dietary supplements. Common dosage forms include powder, hard capsules, and soft capsules. Powders are suitable for users who need flexible dosage adjustments or customized formulations; capsules are the mainstream dosage form, typically containing 100mg or 2,000 FU of active units per capsule, convenient for daily consumption; soft capsules use enteric coating technology to protect the enzyme from stomach acid degradation and improve bioavailability. Nattokinase products are available in different specifications based on their activity, with common levels including 2,000 FU, 5,000 FU, 20,000 FU, and even 35,000 FU, to meet different application scenarios from routine maintenance to high activity requirements.

Choosing our nattokinase powder means choosing a triple commitment: quality assurance, authoritative certification, and flexible service. We use high-quality non-GMO soybeans as raw materials, produced through a deep liquid fermentation process using Bacillus subtilis. This results in stable activity and low impurity content. Each batch undergoes rigorous testing for enzyme activity (FU), heavy metals, and microbial indicators to ensure our products meet high international standards. We are ISO 22000 food safety management system certified and HALAL certified, and our products can provide third-party testing reports and certificates of origin. Regarding customization, we support full-dimensional customization from activity levels (1,000 FU to 35,000 FU), powder fineness, to packaging specifications.Contact us at info@kintaibio.com.
