Nattokinase is a proteolytic enzyme (enzymes that break down proteins) derived from Natto; a traditional Japanese food made from fermented soybeans. Its known for its potential cardiovascular and circulatory health benefits. Key Benefits Include: Circulation and Blood Flow: Nattokinase helps to maintain healthy levels of fibrin by encouraging a healthy balance in blood coagulation for an optimally functioning cardiovascular system. Thrombosis Support: Nattokinase has been shown to promote plasmin, to support with thrombosis (formation of a blood clot inside a blood vessel). Supports Cardiovascular Health: By promoting blood vessel flexibility, Nattokinase may reduce blood pressure, helping to maintain heart health with long-term cardiovascular health in mind. On-going research for anti-atherosclerotic and lipid-lowering effects.
