Two enzymes, two sources
The two enzymes in this capsule have different origins. Nattokinase comes from natto, the stringy fermented soybeans that have been eaten at breakfast in Japan for centuries. Serrapeptase comes from a bacterium in the gut of the silkworm, which uses it to open its cocoon.
Made in the United States
Doctor's Best has the capsules made in the United States. The enzymes are protected with Serrateric™, based on calcium salts, in a delayed-release capsule. The product contains soy.

Interaction of Protein-Breaking Enzymes
Doctor's Best Natto-Serra is a dietary supplement that combines two proteolytic (protein-breaking) enzymes: nattokinase and serrapeptase. These enzymes are derived from natural sources and are valued for their potential to break down proteins. Natto-Serra's unique formula optimises serrapeptase's effectiveness and ensures optimal absorption in the intestines.
What is Nattokinase?
Nattokinase is a protein-breaking enzyme that was originally discovered in the 1980s by Japanese scientist Hiroyuki Sumi. He identified the enzyme during his research on fermenting soybeans with the bacterium Bacillus subtilis to produce natto, a traditional Japanese food. Nattokinase is a serine protease known for its ability to break down fibrin, a protein that plays a key role in the body. Production of nattokinase has been optimized through biotechnological techniques, including heterologous expression in microorganisms, contributing to its availability in supplement form.
What is Serrapeptase?
Serrapeptase, also called serratiopeptidase, is a protein-breaking enzyme originally isolated from the gut of the silkworm Bombyx mori. This enzyme allows the worm to dissolve its cocoon and emerge. Serrapeptase belongs to the family of metalloproteases and is known for its ability to break down proteins. Research has shown that serrapeptase is effective when taken orally, provided it is protected from the acidic environment of the stomach by enteric-coated capsules. Serrapeptase is used in Europe and Asia for various applications.
Formulation and Use of Natto-Serra
Each Natto-Serra capsule contains 40,000 SPU serrapeptase and 2,000 FU nattokinase, along with 29 mg calcium from tricalcium phosphate and calcium stearate. The formulation uses Serrateric™, a technology that protects the enzymes from degradation in the stomach, allowing effective absorption in the small intestine. It is recommended to take one capsule daily without food.
