Both can thin the blood.

Both have mild anti-platelet activity: omega-3 fats subtly reduce platelet aggregation, and ginkgo can do the same through its terpenoids. Alone at normal doses this is rarely an issue, but combined, and especially alongside aspirin, warfarin, or other anticoagulants, the effects can add up and raise bleeding risk.

What to do

For most healthy people, normal doses together are fine. If you take blood thinners or antiplatelet drugs, have a bleeding disorder, or have surgery or a dental procedure coming up, clear it with your doctor first and consider pausing both beforehand.
