Nattokinase (NK), also known as subtilisin, is a serine protease produced by Bacillus subtilis natto during the fermentation of natto. It can be extracted from natto, a fermented soybean made by boiling the beans and combining them with a certain type of bacteria.

So nattokinase, an extract of natto that is often capsuled and taken as a food supplement, dissolves blood clots that can lead to heart attacks and strokes.
