Double Wood Nattokinase is a high-quality dietary supplement formulated to support healthy circulation and cardiovascular function. Sourced from natto, a traditional fermented soybean food, nattokinase is a naturally occurring enzyme widely studied for its role in supporting blood flow and fibrin balance as part of a healthy lifestyle.

This clean, single-ingredient formula is designed for adults seeking targeted enzymatic support for vascular wellness, particularly those focused on heart health, circulation, and longevity-oriented wellness routines.

What Is Nattokinase?

Nattokinase is a proteolytic enzyme produced during the fermentation of soybeans by Bacillus subtilis. It has been used in traditional Japanese diets for centuries through the consumption of natto.

From a biological perspective, nattokinase is known for its ability to interact with fibrin, a protein involved in normal blood clotting processes. For this reason, nattokinase is commonly used in supplements designed to support healthy blood flow and circulatory balance when taken as part of a heart-conscious lifestyle.

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.
