Doctor's Best Natto-Serra combines the power of Nattokinase and Serrapeptase, two natural enzymes with a long history of use as dietary supplements. Serrapeptase (Serratiopeptidase), derived from the Serratia E-15 bacteria found in the Japanese silkworm, is a protein-digesting enzyme. Similarly, Nattokinase, a protein-digesting enzyme derived from fermented soybeans (natto), a traditional Japanese food, is included. This Nattokinase is Vitamin K-free. Our Serrapeptase utilizes Serrateric®, a superior alternative to enteric coating, ensuring the enzyme reaches the intestines for optimal absorption. Experience the benefits of this powerful enzyme blend in convenient vegetarian capsules.
