The Active Ingredient Is: Nattokinase

Nattokinase is an enzyme produced during the fermentation of soybeans, known for its fibrinolytic activity which helps influence normal blood flow. This form is derived from Japanese natto and is used to support vascular function and circulation. The ingredient is vegan and sourced to support gluten-free and non-GMO standards.

This enzyme is produced in a manner that emphasises traditional, plant-based fermentation origins and is used to deliver a functional protein involved in normal bodily processes.

What Does Nattokinase Do?

Nattokinase contributes to normal blood flow by helping to break down fibrin, a protein involved in clot formation, supporting healthy circulation. Scientific findings also indicate potential cardiovascular benefits related to fibrinolytic activity, as noted in recent clinical research.

Dr. Wang of University found that nattokinase supplementation is associated with beneficial cardiovascular effects, including reduced blood pressure and enhanced fibrinolytic activity.
