Nattokinase is a profibrinolytic serine protease originally extracted and purified from natto, a traditional fermented soybean food popular in Japan. The fermentation process includes incubating boiled soybeans with Bacillus subtilis natto. Current research suggests that nattokinase may support healthy coagulation of blood within normal levels, and may be useful in the maintenance and enhancement of normal healthy endogenous fibrinolysis, the dissolution of the essential portion of the blood clot or thrombus.* Maintenance of optimum functioning of the body's fibrinolytic/ thrombolytic mechanisms may benefit the function of many bodily systems, in particular the cardiovascular system and the brain.

Isolated, purified and encapsulated nattokinase, an enzyme derived from boiled soybeans and a selected, patented strain of Bacillus subtilis natto. Nattokinase NSK-SD was the first nattokinase introduced into the US market, and it has established standardization and quality levels for all nattokinase, with comprehensive safety studies and proven potency. It is vegetarian, non-irradiated, and free of vitamin K2. NSK-SD has two Japanese and three U.S. patents, and is recognized by the JHFA (Japan Health and Nutrition Food Authorization) and JNKA (Japan Nattokinase Association) as authentic nattokinase. NSK-SD is a trademark of Japan BioScience Laboratory.
