This new improved Nattokinase from Allergy Research is of the highest potency available, yielding 1,825-2,100 FU per each 100 mg softgel (FU means fibrinolytic units or fibrinolytic activity, that is the ability to dissolve fibrin which, if uncontrolled is a factor in clot formation). The fibrinolytic activity varies because Allergy Research does the diligence to have each batch independently assayed to verify  actual fibrinolytic potency before and after capsulation.  This varies somewhat from batch to batch hence the guaranteed FU range of 1,825-2,100 per softgel.   This product in its new and improved form is more than two times the potency per softgel of our former products and is more readily absorbed.  Natto, the condiment used in Japan, has naturally occurring vitamin K.  This Nattokinase product is vitamin K free further aiding the products ability to thin blood safely and effectively.

It is best to monitor the blood thinning effects of  Nattokinase.  This is best monitored with fibrinogen levels (ideal target = < 250) and a bleeding time to monitor platelet aggregation.   A bleeding time is performed in a physician's office or in a hospital lab by placing a blood pressure cuff on the upper arm at 40 mm of Hg. while using a standardized lancet to prick  the forearm with the Surgicutt^TM bleeding time system.  This bleeding time normally ranges from 2-10 minutes with an ideal blood thinning target between 6-8 minutes.  Please contact you health professional for more information on how to monitoring fibrin with fibrinogen levels and platelet aggregation with bleeding times. 

Each 1 softgel contains:
Nattokinase NSK-SD^TM 100  mg ( 1,825-2,100 FU [batch dependent] )
Vitamin E (as D-alpha-Tocopherol) 10 IU
Actual potency confirmed by independent testing after capsulation.

Other ingredients:
Rice brain oil, lecithin, yellow beeswax, tumeric, titanium dioxide.

Manufacturers suggested dosage:
1 softgel two times daily or as directed by a healthcare provider.  Take with 8-10 ounces of water.  The manufacturer recommends taking Nattokinase with or without food.  Dr. Milner recommends taking Nattokinase on an empty stomach an hour away from food to optimize absorption of the active enzyme and to minimize degradation by stomach acids.
