Nattokinase is an enzyme extracted from natto, a traditional Japanese fermented soybean food. It is best known for its fibrinolytic activity — the ability to break down fibrin, a protein involved in blood clotting.
In sports nutrition, nattokinase is valued for promoting healthy circulation, which can support oxygen delivery and nutrient transport to muscles during physical exertion.
Its cardiovascular benefits, particularly regarding blood flow, may also contribute indirectly to improved performance and recovery.
