Nattokinase Supplementation and Hemostatic Factors

The aim of this study is to examine the effects of nattokinase supplementation on hemostatic factors in nondiabetic and hypercholesterolemic subjects. Collagen-epinephrine closure time, prothrombin time, activated partial thromboplastin time, fibrinogen levels, and lipid profiles were measured at baseline and at 8-week follow-up.
