Best Nattokinase from Doctor's Best delivers pure nattokinase enzyme with all Vitamin K2 removed. Nattokinase is an enzyme derived from "natto," a traditional fermented soy food popular in Japan. During the natto production process, Bacillus subtilis, a friendly bacteria, ferments boiled soybeans, releasing nattokinase.

Summary of Customer Ratings & Reviews

Customer Ratings & Reviews

Best Nattokinase is rated 4.7 out of 5 by 19.
Rated 4 out of 5 by from SUPLIMENT I am taking Sarrapeptase and have read where Nattokinase compliments it very well . I am rather impressed with Sarapeptase and the Doctors Best brand so I decided to try nattokinase from the same manufacture and from Swanson the site I trust most. So far I am not able to apportion any great claims to Nattokinmase as I have just been using it for about 2 weeks --My wife and I ..thus the rather modest ratings .In about 6 months I will be able to give a more conclusive report.

Rated 3 out of 5 by from Not what I anticipated I ordered nattokinase for the vitamin K2, and when I received it, I read that the vitamin K2 had - for some reason - been removed! Perhaps I should have done more research.

Rated 5 out of 5 by from great product All the reviews I've ever read on this product are true. Absolutely amazing. It's important to follow dosing directions and not take with food. I immediately noticed a difference! I use this in conjunction with Colloidal silver and Colloidal minerals. Life saving for me.

Rated 4 out of 5 by from Good Product There is a lot of information on benefits of Nattokinase. This is an easy to take product. I have been taking for years.

Rated 5 out of 5 by from Very excellent value. So happy to find a natto supplement that we could afford since it is not very practical to eat natto in this country. Totally convinced that this is a great supplement after doing my own research on the use of this food and supplement in Japan and their results with healthier blood supply. Look it up on a search engine yourself and see why the Japanese are so healthy.

Rated 4 out of 5 by from Cardiovascular help I've read that nattokinase is one of the best supplements to take for the cardiovascular system. It's a bit pricy and I don't know whether it is really helping or not. But on those days when I don't have time to jog/workout, I take it. My theory is that if I don't get any exercise during the day, I should still try to do something good for my cardiovascular system. Perhaps it's crazy but it makes me feel less guilty about missing out on exercise that day.

Rated 5 out of 5 by from One Great Product I was introduced to Nattokinase a year ago, but it is very expensive when purchased locally. I found doctors Best brand and I am amazed at the quantity and quality of this great product. It worked for me immediately and I use it everyday. It is indeed one great product Swanson has here!
