Product Description

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.

Product Benefits

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.
