Nattokinase is an enzyme that is produced by bacteria which plays a central role in the fermentation of soybeans into the Japanese food natto. Recent studies have shown nattokinase to be a strong fibrinolytic and thrombolytic agent. When means that is reported to prevents blood clots from growing and also dissolve blood clots to limit the damage that could be caused by blockage. Studies have shown that this effect is done via several different pathways simultaneously. Nattokinase has also been investigated for the treatment of hypertension, Alzheimer's disease, and eye disorders. In a double bind placebo controlled cross-over nattokinase intervention study done on 12 healthy young males found that a single does effected both thrombolytic and fibrinolytic activity. A study done on rats has determined that the oral consumption of nattokinase is of low toxicological concern.
