The Benefits

Supports Cardiovascular health*

Natto-K™ contains specialized blends of enzymes including Nattokinase with NSK-SD®—the only form of nattokinase that does not contain vitamin K2—to enhance the body’s production of plasmin.*

Plasmin breaks down excess fibrin, which may improve circulation.* Natto-K helps maintain normal levels of blood clotting factors within a healthy range,* and promotes optimal circulation and cardiovascular health.* 

Usage & Notes

Recommended Use: 1 capsule three times daily on an empty stomach, one hour before or two hours after a meal.

Enzymedica does not use ingredients produced using biotechnology.

Consult with a physician prior to use if pregnant or nursing.

The Science

Fibrin circulates through the blood and sticks to the walls of blood vessels. Maintaining healthy levels of fibrin promotes healthy coagulation of blood for an optimally functioning cardiovascular system.*

Dr. Hiroyuki Sumi, a researcher for the Japan Ministry of Education, found that a part of the Japanese fermented soybean food known as natto exhibited strong fibrinolytic activity, meaning that it is effective in breaking down fibrin, a protein that is involved in clotting the blood.(1)* He named the enzyme responsible for this activity ‘nattokinase.’

Dr. Sumi later commented that nattokinase showed “a potency matched by no other enzyme.”
