OL uses only the highly bioavailable, proprietary extract of natto. Nattokinase is a serine protease type enzyme derived from fermented soybeans. Research has shown nattokinase to support healthy coagulation of blood and enhance fibrinolytic (breaking up of clots) activity. Fibrin is a protein that, when activated, forms fibrinogen which is responsible for blood clotting.
