Compounded blood-thinning effect.

Both reduce clotting through complementary routes, ginkgo by inhibiting platelet aggregation and nattokinase by breaking down fibrin. Together, or on top of an anticoagulant, the combined effect can push bleeding risk higher than either alone.

What to do

Avoid pairing these without a clinician's sign-off, especially if you take blood thinners, have a bleeding disorder, or have surgery scheduled. Stop both well before any procedure.
