Key Benefits

  • Supports Healthy Blood Flow: Nattokinase may help support healthy blood circulation by lowering plasma levels of proteins that may inhibit blood flow.
  • Supports Cardiovascular Health: Research suggests Nattokinase may support cardiovascular health by promoting healthy circulation.


Nattokinase is one of many different enzymes isolated from the fermented food product known as Nattō. (Fermented, boiled soybeans). Nattokinase has become popular as a supplement in recent years due to its fibrinolytic properties allowing it to degrade fibrin which can help support healthy blood flow and overall cardiovascular health.

Nattokinase varies in potency from 1000 FU / 100 mg to 2000 FU / 100 mg, FU stands for fibrin units which as an activity unit quantifying the ability of a given Nattokinase supplement to degrade fibrin. Our Nattokinase supplement is highly potent at 2000 FU / 100 mg.
