Product education

Nattokinase NSK-SD®: Natural Support for Healthy Blood Flow*

Nattokinase NSK-SD® by SFI Health is a specialized supplement featuring a powerful proteolytic enzyme designed to support healthy circulation and blood flow. Nattokinase’s primary effect is fibrinolysis—the breakdown of fibrin, a protein that is essential for the formation of blood clots. By helping to maintain the optimum function of the body’s normal fibrinolytic processes, this formula provides targeted support for cardiovascular wellness. It is produced from the fermentation of non-GMO soybeans and is standardized to fibrin activity units, ensuring consistent potency and quality.*

How It Works: Promoting Healthy Fibrin Degradation

This formula works by supporting the body’s natural mechanisms for managing blood clots and maintaining clear vessels.*

A Powerful Fibrinolytic Enzyme
Nattokinase directly degrades excess fibrin, helping to break down unwanted blood clots in vessels. In addition to its direct action, it also upregulates the body’s own natural mechanisms that guard against excess fibrin formation, providing a dual-action approach to supporting healthy blood flow, circulation, and platelet function.*

Standardized and Vitamin K Free
This formula uses NSK-SD®, a branded form of nattokinase that is standardized for potency, ensuring you receive 2,000 Fibrin Units (FU) of activity in every capsule. Importantly, it has been processed to be free of vitamin K, making it a suitable choice for individuals concerned with vitamin K intake.
