Nattokinase, by Seeking Health, is formulated with a unique enzyme that supports healthy clotting function and circulation.*

Nattokinase is derived from natto, a fermented soy food that is an integral part of traditional Japanese cuisine, and has been shown in studies to benefit the cardiovascular system.*

Nattokinase Benefits:

  • Supports normal blood clotting: Nattokinase has been shown to help maintain optimum functioning of the body’s normal activity of breaking down the fibrin component of blood clots, thus supporting healthy blood clotting and circulation.*
  • Supports removal of excess blood clots: Since small clots are formed continually throughout the body following injury to a blood vessel wall, the removal of unneeded clots when healing has occurred is crucial.*
  • Overall cardiovascular benefit: In addition to its favorable fibrinolytic activity, Nattokinase may also provide significant support to the normal flow of blood by helping regulate red blood cell aggregation and blood viscosity.*

What’s so important about blood clots?

Fibrin is a fibrous insoluble protein that comprises a mesh essential for blood clot formation when linked together. The delicate balance between the formation and breakdown of fibrin is extremely important. Without enough fibrin, any damage to the circulatory system would result in uncontrollable bleeding or blood loss. On the other hand, excessive fibrin formation is associated with abnormal blood clot formation and inflammation. Nattokinase by Seeking Health has an excellent safety profile and may be used by individuals seeking natural support for blood clotting and circulation functions.* This product is free of vitamin K.
