Discovery of Nattokinase
Dr. Hiroyuki Sumi, M.D. (a.k.a. Dr. Natto), a researcher of the Japan Ministry of Education and majoring in physiological chemistry at the blood laboratory of the University of Chicago, had long researched thrombolytic enzymes (enzymes that break down blood clots). Dr. Sumi found that a part of the Japanese food known as natto exhibited a strong fibrinolytic activity.1 Fibrin is a protein that forms and circulates through the blood and sticks to the walls of blood vessels. This is a contributing factor to the formation of clots, slows blood flow and increases blood viscosity (stickiness or thickness of the blood). 

He named the corresponding fibrinolytic enzyme “nattokinase.” Dr. Sumi commented that nattokinase showed “a potency matched by no other enzyme.”

Natto-K, with nattokinase blend containing NSK-SD®, is a particularly potent enzyme formula which may enhance the body’s production of plasmin (the enzyme the body produces to dissolve clots), thus encouraging optimal heart health.*2

Natto-K was formulated to  contain a synergistic blend of  nattokinase, protease, lipase, amylase and cellulase Thera-blend™ enzymes to promote optimal circulation and support cardiovascular health.*

What Are Enzymes?

Enzymes are biologically active proteins found in all living cells. Metabolic enzymes catalyze and regulate every biochemical reaction that occurs within the human body, making them essential for cellular function and overall health. Digestive enzymes turn the food we eat into energy which may be utilized by the body for various biological processes. Our bodies naturally produce both digestive and metabolic enzymes, as they are needed.
