In this short video, Dr. Chad Larson discusses the health benefits of nattokinase.

My notes:

• Nattokinase is a fibrinolytic enzyme that breaks down fibrin in the blood.    Fibrin is the long, fibrous protein that is involved in blood clotting.  When you cut yourself, these chains of fibrin are layered over the wound to block the flow of blood.  That’s fine when we are talking about wounds, but clotting can occur within the circulatory system.
• When fibrin builds up, blood thickens and slows down circulation.  This is important for anyone with a history of blood clots.
• Nattokinase dissolves fibrin, reducing the problem.  It does not affect the coagulation of blood unlike some other supplements.
