The Japanese have consumed a dish known as Natto for centuries which contains the heart healthy enzyme nattokinase. Nattovena is the world's strongest pure-nattokinase product on the market, rated at 4,000 fibrinolytic (fibrin-dissolving) units of activity per capsule. Nattovena supports circulatory and heart health by assisting in cleansing the body of potentially harmful blood-borne particulates such as fibrin.

Nattovena is a powerful blood-cleansing enzyme, formulated to help maintain normal cardiovascular health.
