Lumbrokinase vs Nattokinase vs Serrapeptase: Key Differences, Benefits, Risks & Practical Guide (2026)
Lumbrokinase, nattokinase, and serrapeptase are all enzymes that have been studied for their potential health benefits. They are all considered as proteolytic enzymes. Proteolytic enzymes have a variety of roles in the body, from helping to digest food to taking part in the immune response. While interest in these compounds has grown, it’s important to understand their mechanisms, evidence base, and safety considerations clearly. What is Lumbrokinase? Lumbrokinase (LK) is an enzyme derived from earthworms is thought to aid in blood clot prevention, inflammation reduction, and circulation problems. Lumbrokinase for Blood Clots Thrombolytic agents typically used to dissolve clots are urokinase (u-PA), streptokinase, and tissue plasminogen activator (t-PA). These drugs, however, are not specific for fibrin and have adverse and dangerous side effects including severe bleeding and heavy blood loss which may result in death. In contrast, LK is very specific to fibrin as a substrate and ...
