Nattokinase is a powerful enzyme used to support normal blood flow, circulation and blood pressure levels. Derived from a highly purified extract of the traditional Japanese food natto, nattokinase is an all-natural, highly active enzyme that helps promote normal levels of fibrin. Fibrin is a filamentous protein formed in blood, which can accumulate along blood vessel walls and affect blood flow. Research has shown nattokinase closely resembles plasmin, the only endogenous enzyme that directly dissolves fibrin. It is thought to increase the body’s production of plasmin. Nattokinase has been shown to support activation of many of the body’s 3,000 endogenous enzymes. In addition, while many of the agents involved in promoting healthy blood flow and coagulation either have limitations, and or serious side effects, this formulation of NATTO K has a potent support activity that lasts for an 8-12 hour period and is safe for long-term use. Each capsule of NATTO K contains 50 mg of nattokinase.
