Health interest: Heart Health
  • Doctor’s Best Natto-Serra is a combination of two natural enzymes serrapeptase and nattokinase, and supports healthy immune response and supports healthy circulation.*

  • Nattokinase, a fibrinolytic enzyme, breaks down blood clotting fibrin while Serrapeptase (serratiopeptidase) is a protein-digesting enzyme isolated from the friendly bacterium Serratia E-15

  • Doctor’s Best uses serrapeptase made with Serrateric™, a superior alternative to enteric coating that protects the enzyme until it reaches the intestines for optimal absorption.*

  • Nattokinase is derived from "Natto", a fermented soy food popular in Japan for centuries.

What is Doctor’s Best Natto-Serra?

Doctor’s Best Natto-Serra supports healthy immune response and supports healthy circulation.* It is a combination of two natural proteolytic enzymes, serrapeptase and nattokinase. Serrapeptase (serratiopeptidase) is a protein-digesting enzyme isolated from bacteria isolated from the intestine of silk worms (Serratia E-15). The serrapeptase is formulated with Serrateric™, a superior alternative to enteric coating that protects the enzyme until it reaches the intestines for optimal absorption. Nattokinase is derived from "Natto", a fermented soy food popular in Japan for centuries.

How does it work?

Natto kinase is an enzyme that is found in traditional Japanese soy cheese that is also known as natto. Natto has been shown to exhibit a fibrin lytic effect in the blood stream. It has the capability to break down blood clots. Nattokinase was discovered I 1980 by a doctor from Miyazaki Medical College in Japan. Since its discovery, the cardiovascular effects of Nattokinase have been studied in many countries. Nattokinase reinforces the actions of plasmin, which your body uses to break down the body’s blood clotting agent, fibrin, and thereby prevents abnormal thickening of the blood. Nattokinase prevents aggregation of red blood cells. Because of its clot-busting and blood-thinning properties, nattokinase should not be taken with other blood thinners. Since nattokinase supplementation resulted in reduced blood pressure (SBP and DBP), increased intake of nattokinase may play an important role in preventing and treating hypertension.* Since Nattokinase has the ability to break down non-living tissue in the body, it has the distinct ability to digest non-living tissue that clog the lining of our arteries. This is one reason why it’s so good at keeping arterial deposits from building up after heart surgery. Serrapeptase has other applications. Serrapeptase is an immunologically active enzyme. It can bind itself to the alpha 2 macroglobulin in our plasma where it is shielded from the immune system while retaining its enzymatic activity, and in this way it is transferred to the sites where it is needed in the body. It is this same type of specific action that allows silkworms to eat its own protective cocoon, digest it without any side effects.

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.

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

The purines are not removed from Doctor's Best Nattokinase.

What does NSK-SD mean?

NSK-SD is simply the trademarked name of the nattokinase enzyme that is produced by Japan BioScience Laboratory.

Why are you not showing the mg of Nattokinase on your label and what does FU stand for?

ALL enzymes are measured in enzymatic units.  FU is fibrinolytic units, a measure of enzymatic activity.

Why isn't Doctor's Best Nattokinase enteric coated?

Doctor's Best is committed to using the highest quality Nattokinase manufactured and independently tested at the industry recognized enzyme manufacturing facility, Deerland Enzymes in Kennesaw, Georgia. We believe by utilizing this manufacturing technology we are providing the highest quality Nattokinase available at an affordable price point. 

What is the country of origin for Doctor's Best products?

Doctor’s Best products are quality tested and manufactured in the United States using highly qualified cGMP manufacturers and raw material ingredients. Doctor’s Best sources raw materials from around the world and ingredients are subject to the intense testing and verification regardless of geography of origin.

Do not use this product if you are pregnant or nursing, are allergic to soy, or if you have a blood coagulation disorder. If you are taking an anticoagulant (blood-thinning medication) or vitamin K, consult a doctor before taking this product. Contains Soy
