Nattokinase is an enzyme derived from "natto", a traditional fermented soy food popular in Japan. During the natto production process B. subtilis natto, a friendly bacteria, ferments boiled soybeans, releasing nattokinase. Best Nattokinase contains pure nattokinase enzyme with all Vitamin K removed.


270 veggie caps


Doctor's Best Nattokinase (2000FU) contains 2,000 fibrinolytic units, which refers to the enzyme activity level. Enzymes, like Nattokinase, are not measured in mg, but in an unassociated measure of units. Even if the enzyme had 1,000mg per cap but no activity, the enzyme would be worthless. Doctor's Best Nattokinase has 2,000FU (units) of activity. This is a very high amount of activity.
