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 produced from non-genetically modified soybeans using a selected, patented strain of Bacillus subtilis natto. Each batch is tested to ensure potency.
