Enzymedica’s Natto-K contains Nattokinase NSK-SD (shown to break down fibrin), and 12 synergistic enzymes to support cardiovascular health.

Natto-K with nattokinase blend containing NSK-SD® is a particularly potent enzyme formula which may enhance the body’s production of plasmin (the enzyme the body produces to dissolve clots), thus encouraging optimal heart health.  Nattokinase can be used preventatively and has proven efficacy. Nattokinase NSK-SD has been the subject of 17 studies, including two human trials.

Blood Plasma Tests: Nattokinase has been the subject of 17 studies, including two small human trials. Researchers from JCR Pharmaceuticals, Oklahoma State University, and Miyazaki Medical College tested nattokinase on 12 healthy Japanese volunteers (6 men and 6 women, between the ages of 21 and 55). They gave the volunteers 200 grams of natto (the food) before breakfast, then tracked fibrinolytic activity through a series of blood plasma tests. The tests indicated that the natto generated a heightened ability to support circulation. On average, the volunteers'' ELT (a measure of how long it takes to dissolve a blood clot) dropped by 48 percent within two hours of treatment.
