Nattokinase is a proteolytic enzyme whose principle effect is fibrinolysis or degradation of fibrin, a fibrillar protein that when linked together forms the mesh essential for blood clot formation.^† Nattokinase also upregulates the body’s natural mechanism that guards against excess fibrin formation.^† Nattokinase may support healthy blood clotting, circulation, and platelet function by helping to maintain optimum function of the body’s normal fibrinolytic processes.^† Produced from fermentation of non-GMO soybean isolates by Bacillus subtilis natto. Standardized to fibrin activity units and free of vitamin K.

Other Ingredients:

Microcrystalline cellulose, vegetarian capsule (hydroxypropyl methylcellulose, water), L-leucine, and silicon dioxide.

ΔFibrinolytic units or fibrin degradation units (FU) is a measure of enzyme activity. Nattokinase NSK-SD® is standardized to contain 2,000 FU per capsule.
