What Is Nattokinase? An Evidence-Based Overview

Nattokinase is an enzyme extracted from natto, a traditional Japanese food made by fermenting soybeans with the bacterium Bacillus subtilis. Despite its name, it is not a kinase — it belongs to the serine protease family, a group of enzymes that break down proteins. The name reflects its discovery in natto, not its biochemical function, which can be a source of confusion. This enzyme has drawn attention for its potent fibrinolytic activity, meaning it can dissolve fibrin, a protein involved in blood clotting.
