Description
Nattokinase Product Overview
Nattokinase is an enzyme that the bacterium Bacillus subtilis var. natto produces during the fermentation of soybeans. The commercial grade is an off-white to cream-colored powder, standardized by enzyme activity in fibrinolytic units (FU) per gram, typically 20,000 to 40,000 FU/g.
In addition, producers of nutritional products use it in capsules and tablets, often enteric-coated to protect the enzyme from stomach acid, under the regulations of each market. Similarly, vitamin K2-free grades are offered, because natto naturally contains vitamin K2, which some formulations need to exclude.
As an enzyme, nattokinase loses activity with heat and moisture, so it needs cool, dry storage. Other enzymes in our range also include Bromelain and Lactase.

Frequently Asked Questions
What does FU/g mean?
FU stands for fibrinolytic units, the standard measure of nattokinase activity; higher values mean stronger activity per gram.
Do you supply vitamin K2-free grades?
Yes. Because natto naturally contains vitamin K2, K2-free grades are also available on request.
How can I get a price and documents?
Prices depend on quantity, packaging and destination, so please contact us with your required volume. We then send a quotation together with the CoA and SDS.
