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.
