Nattokinase vs. Lumbrokinase: Origins and Potency
While both nattokinase and lumbrokinase are potent enzymes known for their fibrinolytic (clot-dissolving) properties, they originate from different sources and exhibit varying levels of activity. This distinction is a primary factor in determining which one might be more suitable for your specific health needs.
Nattokinase is a serine protease enzyme derived from natto, a traditional Japanese food made from fermented soybeans. The fermentation process, which uses the bacterium Bacillus subtilis natto, is what creates the enzyme.
Lumbrokinase is a group of fibrinolytic enzymes extracted from earthworms (Lumbricus rubellus). Unlike nattokinase, which is a single, well-defined enzyme, lumbrokinase is a complex mixture of enzymes, and its composition can vary depending on the extraction process.
Research suggests that lumbrokinase may have higher enzymatic activity and a more powerful, targeted fibrinolytic effect than nattokinase on a per-milligram basis. This superior potency makes lumbrokinase potentially more effective for acute or severe clotting concerns.
Comparing the Mechanisms of Action
Beyond potency, the way these enzymes operate in the body also differs slightly, which influences their overall health benefits.
- Nattokinase: It works by directly breaking down fibrin, the protein that forms blood clots. It also indirectly increases the body's production of plasmin, the natural enzyme that dissolves clots, and inhibits the angiotensin-converting enzyme (ACE), which helps lower blood pressure. This multi-faceted approach offers broader cardiovascular protection.
- Lumbrokinase: Primarily a direct-acting fibrinolytic agent, it is known for its ability to break down excess fibrin and clots. It is also noted for having faster absorption and a prolonged action compared to nattokinase, providing a sustained effect in maintaining healthy blood circulation.
A Comparison Table: Nattokinase vs. Lumbrokinase
To help visualize the differences, here is a detailed comparison:
| Feature | Nattokinase | Lumbrokinase | 
|---|---|---|
| Source | Fermented soybeans (natto) | Earthworms (Lumbricus rubellus) | 
| Potency | Generally lower fibrinolytic activity on a per-milligram basis. | Higher enzymatic activity and more potent fibrinolytic effect per milligram. | 
| Mechanism | Directly breaks down fibrin; indirectly boosts plasmin; inhibits ACE. | Primarily a direct fibrinolytic action; maintains prolonged effect. | 
| Absorption | Stable for oral administration, absorbed intact. | Noted for faster absorption and sustained action. | 
| Secondary Benefits | Blood pressure regulation; anti-inflammatory; potential sinus health support. | Supports blood circulation and reduces blood viscosity; potential neuroprotective effects. | 
| Duration of Action | Typically used for general, long-term cardiovascular support. | Potentially more beneficial for acute, short-term clotting management. | 
| Allergy Concerns | Contains soy, so individuals with soy allergies should avoid it. | Does not contain soy; suitable for those with soy sensitivities. | 
Choosing Between Nattokinase and Lumbrokinase
Selecting the right enzyme depends on your specific health objectives and sensitivities. Here are some guidelines to consider:
- For Broader Heart Health and Blood Pressure Support: Nattokinase is often the preferred choice for those focused on general cardiovascular wellness and managing blood pressure. Its ACE-inhibiting properties and ability to be taken as a consistent, long-term supplement make it ideal for preventative care.
- For Acute Clot Management and Targeted Fibrinolysis: If the primary concern is acute clot dissolution or more potent fibrinolytic activity, lumbrokinase is often considered the stronger option. Its targeted, potent effect makes it potentially more suitable for specific, short-term support, often under medical supervision.
- For Individuals with Soy Sensitivities: Nattokinase is derived from soybeans and is unsuitable for those with soy allergies or sensitivities. Lumbrokinase, sourced from earthworms, is the clear choice in this situation.
- For Balancing Bleeding Risks: While both enzymes carry a risk of increased bleeding, particularly when combined with other anticoagulants, nattokinase is generally considered to have a milder effect than lumbrokinase. Consult a healthcare provider before use, especially if taking blood-thinning medications.
Important Considerations and Potential Risks
Before starting any new supplement, including nattokinase or lumbrokinase, it is crucial to consult with a healthcare professional. These enzymes are powerful and can have significant effects on blood clotting. Individuals on anticoagulant or antiplatelet medications should be especially cautious, as combining these supplements can increase the risk of excessive bleeding.
Furthermore, supplement dosage can vary. The potency of lumbrokinase, in particular, can be influenced by the extraction and manufacturing process, as it is a complex of enzymes. It is always recommended to choose high-quality, research-backed products and to follow the guidance of a qualified healthcare provider. For more information on the efficacy of nattokinase, studies published by the National Institutes of Health can be a valuable resource.
Conclusion
In the debate of is nattokinase or lumbrokinase better, the answer depends heavily on your specific health goals. Lumbrokinase offers superior, faster-acting fibrinolytic potency, making it a stronger candidate for targeted, acute clot management. Nattokinase, with its broader cardiovascular benefits like blood pressure support, is better suited for long-term, general heart health maintenance. Both enzymes are powerful allies in supporting cardiovascular health by breaking down fibrin, but their different mechanisms and applications mean a personalized approach is necessary. Consulting a healthcare provider is the most important step in choosing the right enzyme for you.
