The Active Ingredient Is: Nattokinase (enzyme)

Nattokinase is an enzyme derived from fermented soybeans, providing a natural enzymatic activity in the bloodstream to support normal physiological processes.

This formulation uses a vegan production method with Vitamin K2 removed to reduce clotting risk, and is intended for daily cardiovascular support through its enzymatic action.

What Does Nattokinase Do?

Nattokinase participates in fibrin processing and supports normal circulatory function by promoting endogenous fibrinolysis, a mechanism discussed in EFSA-aligned discussions of enzyme activity in the blood system.

Clinical observations have shown that daily nattokinase intake can be associated with improvements in cardiovascular markers and blood flow, as reported by Dr. Sumi of a Japanese university in research from 2022.
