Fibrinolytic enzyme in Natto


Back in 1987, researchers in the Department of Physiology, Miyazaki Medical College, Japan, published a paper in Experientia to show that there was strong fibrinolytic (meaning to break up fibrin, a protein in the blood used in clotting) activity in the vegetable cheese Natto.  Natto is a soybean product popular in Japan.

The activity of the enzyme was around 40CU/g wet weight Natto.  This enzyme is nattokinase.

The scientists were able to extract the enzyme easily using saline solution.

About Andy

I suffered a serious neck injury when I was about 19 years old. That problem didn't affect me until I was in my 40s, but I then suffered two prolapsed discs in my neck and problems with my right arm and hand. Serrapeptase was recommended by my chiropractor to try to break up the scar tissue around the vertebrae that were causing me the problems. It seemed to help me with my problem, so created this site to help inform people what serrapeptase is, what it can do and just as importantly, what it cannot do. I hope you find the information useful.
