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.
Suggested Use
As a dietary supplement, 1 or 2 softgels three times daily, or as directed by a healthcare practitioner. May be taken with or without food. Take with 8-10 ounces of water. If taken with anticoagulant drugs, use under medical supervision. Contraindicated in any condition associated with bleeding.
We originally offered Nattokinase which had 276 mg per 2 capsules, yielding about 1000 FU (FU means fibrinolytic activity, the ability to dissolve blood clots). We are now using Nattokinase with a higher potency, yielding 1440 to 2000 FU per 2 capsules.
