Your body uses fibrin to help form clots and repair damage. Once that job is finished, fibrin is supposed to be broken back down and cleared. But inflammation and metabolic stress can interfere with this cleanup process, allowing fibrin to linger where it shouldn’t.

Over time, that can make blood flow less efficient and place more strain on your cardiovascular system—all while giving you little or no warning that anything is changing. In other words, the problem can be building long before you feel it.

Nattokinase is an enzyme derived from natto, a traditional Japanese fermented soybean food. It supports your body’s normal fibrin-breakdown process and helps maintain healthy circulation and blood flow.
