Clinical Research Highlights
Clinical Research Highlights
-
A comprehensive review notes that nattokinase has been studied for supporting healthy blood flow, through mechanisms such as fibrinolysis, antiplatelet activity, and improved microcirculation.
-
Specific to the NSK‑SD® brand: the ingredient manufacturer reports human trials showing improvement in peripheral blood flow and platelet/red‑blood‑cell aggregation with NSK‑SD®.
-
Safety data: A toxicological assessment found no significant adverse events at studied doses in healthy volunteers for NSK‑SD®.
-
Important safety note: Because nattokinase supports fibrinolytic processes, individuals on anticoagulant or antiplatelet medications, or with bleeding/clotting disorders, should consult their healthcare provider before use.
