Applications
Where this ingredient fits
Use this whenβ¦ β practical formulation guidance for each downstream application.
Enzyme supplement capsules and tablets
Supplement brands, capsule plants and tablet manufacturers
Use the 20000 FU/g grade when the procurement brief is built around enzyme activity and clear batch documentation.
Solid beverage and functional food powder
Functional food, sachet powder and drink mix teams
Compare 10000 FU/g or natto freeze-dried powder routes when flavor, solubility, activity retention and cost are more important than a single high-activity marker.
Distributor sample and COA screening
Ingredient distributors, importers and sourcing teams
Use the 100g sample pack to screen documents, batch photos and customer demand before committing to kg or drum procurement.

Everything buyers need to know about nattokinase
Technical depth that helps formulators and procurement teams choose with confidence.
What is Nattokinase?
Nattokinase is a fibrinolytic serine protease produced during the fermentation of soybeans with Bacillus subtilis (natto). Activity is expressed in fibrinolytic units (FU), and our standard is 20,000 FU/g, with 5,000, 10,000 and 3,000 FU/g freeze-dried grades available.
Fermentation origin
The enzyme comes from controlled submerged fermentation of Bacillus subtilis on a soy substrate - not from natto food directly. Fermentation conditions set the final activity, so the FU/g value is the spec that matters.
Activity, grades and stability
We standardize to a declared FU/g and verify activity by a fibrinolysis assay. Nattokinase is sensitive to heat and gastric acid, so enteric protection is common in finished capsules; activity must also hold across the stated shelf life.
Applications
Nattokinase is used in enzyme and cardiovascular-support supplements - capsules, tablets, solid beverages - often paired with other circulatory botanicals. Formulators should plan for enteric delivery and allergen (soy) labeling.
Quality and safety
We test FU activity, heavy metals, microbiology and absence of recombinant DNA, and label the soy allergen. Production follows GMP and HACCP, with COA and SDS per batch.
RFQ checklist
Confirm the FU/g grade, whether an enteric-compatible grade is needed, any soy-free requirement, pack size and the activity-stability data across shelf life. Those details define the right quote.
