A nattokinase product is only its activity number. Buyers should treat the FU assay as the product, and everything else as packaging.
This article answers "how to verify nattokinase FU activity from a supplier" and keeps nattokinase activity assay tied to a real buyer task rather than a hidden keyword list. A buyer searching for nattokinase 2000 FU supplier can use the same questions to compare suppliers.
Start with the formula brief
Nattokinase is an enzyme derived from natto fermentation, dosed in fibrinolytic units rather than milligrams. In a 2008 randomized, double-blind trial of 86 adults with elevated blood pressure, 2000 fibrinolytic units daily for eight weeks was associated with modest blood-pressure reductions versus placebo. The evidence base remains small, and nattokinase is not a substitute for cardiovascular care.
Documents and testing to request
- Current formula and serving specification.
- Botanical identity, plant part and extract or marker method where relevant.
- Finished-product COA, microbial and heavy-metal results, allergen statement and stability information.
- Packaging, lot coding, storage and destination-market label review.
How to start a practical inquiry
State target FU per softgel, K2-removed or standard preference, additional complex ingredients, destination market and volume. The distributor team can provide current documentation for SKU FB36640.
