Nattokinase NSK-SD®

Nattokinase NSK-SD® from Greatlife is nattokinase of the highest quality. It contains NSK-SD®, the most studied and patented form of nattokinase, produced by fermenting non-GMO soybeans with a specific Bacillus subtilis natto strain. Nattokinase is a powerful fibrinolytic enzyme that helps break down fibrin, a protein that in excess can negatively affect blood circulation. The product is pure, free from additives, toxins, and GMOs.

Nattokinase is a powerful proteolytic enzyme that primarily breaks down fibrin, a protein that plays a central role in blood coagulation. The exact substances nattokinase breaks down include:

• Fibrin – A thread-like protein formed during blood coagulation that can contribute to blood clot formation.
• Plasminogen Activator Inhibitor-1 (PAI-1) – A protein that inhibits the body's natural fibrinolytic processes. By reducing PAI-1, nattokinase can promote fibrin breakdown and support normal blood flow dynamics.
• Thrombin – An enzyme that catalyzes the conversion of fibrinogen to fibrin during blood coagulation. Nattokinase may help modulate thrombin activity and thus influence the coagulation process.

Important to note:

• Nattokinase does not break down collagen, elastin, or other structural proteins, making it specific to fibrinolytic processes.
• The effect of nattokinase resembles the body’s natural enzyme plasmin, which is responsible for breaking down excess fibrin.

Nattokinase NSK-SD®

NSK-SD® is the highest quality nattokinase available. It is extracted from fermented soybeans and a patented strain of Bacillus subtilis natto and is completely pure, without additives or preservatives. Nattokinase NSK-SD® from Greatlife is entirely plant-based, non-irradiated, and contains no vitamin K2. Although nattokinase is the name of a single enzyme, many copies on the market claim to be nattokinase. For example, a peptidase produced by Bacillus subtilis in Japan, a protease produced by Bacillus subtilis in Taiwan and China, and a composite protease enzyme from Aspergillus oryzae in the USA are all sold as nattokinase. All these claim to be "nattokinase," but are actually other enzymes. These enzymes can partially dissolve artificial fibrin in a petri dish, but this does not mean the same reaction occurs in the human body. Furthermore, the safety of consuming these enzymes is questionable. NSK-SD® from Japan Bio Science Laboratory (JBSL) is the only nattokinase that has published data regarding safety and efficacy. It is important to ensure that you purchase genuine nattokinase and not an imitation that uses published data about NSK-SD® from JBSL. They have developed an identification method for nattokinase that can distinguish genuine nattokinase from other enzymes. Using this method, they identify differences between true nattokinase and pseudo-nattokinase. With two Japanese and three American patents, it has been recognized by both JHFA (Japan Health and Nutrition Food Authorization) and JNKA (Japan Nattokinase Association) as genuine nattokinase.
