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.

I love Nattokinase

Posted by 5521543133275000168 on Jan 05, 2017

I love and trust Nattokinase. I feel much safer taking this as a blood thinner/clot buster than I do any pharmaceutical. Since we can't get it anywhere in Canada, I did a simple on-line search for it; I want Nattokinase and will accept nothing else.

And even helped to make the BP reading the same for both my husband's left and right arm (used to differ for about 10 points or so)

This is a good product I recommend it

Posted by Reviewer1620993 on Nov 30, 2016

Been using this product for some months now. It seems to work well for me. I like it because it gives me a source of Omega 3 and also is a blood thinner. Both those are things I need. Since I am vegetarian, getting Omega 3 has not been easy. Fish oil and Krill are off my dietary list. Flax Seed I use but there is not enough research to show that Omega 3 is really very available from the flax. So when Nattokinase became available I was very pleased. i have recommended this product to a friend who needs both the Omega 3 and the blood thinning. He is also happy with this product.
