A researched enzyme.

Join the thousands of wellness seekers around the globe that trust Doctor’s Best Nattokinase to keep their hearts healthy. Nutritionists and researchers have found that nattokinase—an enzyme derived from natto, a traditional Japanese food made from soybeans fermented with a type of bacteria—can make a significant impact in supporting our circulation and cardiovascular health at any age.*

A nattokinase origin story.

Nattokinase was discovered as a viable nutritional supplement in the 1980s when Dr. Hiroyuki Sumi studied 173 kinds of natural foods in an attempt to find a suitable protease enzyme to support circulatory health. Since then, multiple authors have published scientific studies describing the positive effects natto can have on our heart health.


Each veggie capsule contains 2,000 fibrinolytic units (FU) of nattokinase. Take one capsule daily, between meals.

Are the purines removed from the Doctor's Best Nattokinase?

The purines are not removed as they are naturally occurring and lower in Doctor's Best Nattokinase than in food.

How is Nattokinase produced?

Natto is produced by a fermentation adding the bacteria Bacillus subtilis to boiled soybeans. The resulting Nattokinase enzyme is produced when Bacillus subtilis acts on the soybeans. While other soy foods contain enzymes, it is only the natto preparation that contains the specific Nattokinase enzyme.
