What it is
Lumbrokinase is a group of earthworm-derived proteolytic enzymes with fibrinolytic activity measured by enzyme units, not weight alone.
Core function and why it is studied
Its composition or proposed mechanism makes cardiovascular function logical research areas. Studies therefore examine blood-flow and clotting-related laboratory measures. That biological connection explains why it is studied; it does not by itself establish a meaningful benefit.
What the evidence means
Reliable direct human evidence is not sufficient to support a product-wide benefit claim. Laboratory, animal, or traditional-use evidence should not be presented as a demonstrated human outcome.
How to compare products
Compare declared enzyme activity units, source, serving conditions, allergen information, and storage requirements; milligrams alone are not enough.
