Nattokinase is an enzyme derived from "natto," a traditional fermented soy food popular in Japan. During the natto production process, friendly Bacillus subtilis bacteria are boiled and fermented using non-GMO soybeans to produce nattokinase. Doctor's Best Nattokinase contains nattokinase enzyme with Vitamin K2 removed. Nattokinase has been shown to decrease plasma levels of fibronogen and supports a healthy circulatory system.

No effect

Posted by chriswillisau on Oct 09, 2016

I can't give a better or worse star rating for something if I see no effect, but at least this is a good price for 90 tablets.

Side improvement

Try to take this for helping problem of blood clot. Though this cannot be seen, my blood pressure seems to lower and stablize. Will continue to use it as it may reduce or even replace medicine for hypertension in long run.
