Can You Take Evening Primrose Oil and Krill Oil Together?

Use extra care with this pair

The short answer

Evening Primrose Oil has antiplatelet or blood-thinning properties, while Krill Oil inhibits platelet aggregation via omega-3 fatty acids. Taking both may amplify blood-thinning effects through different mechanisms.

How to arrange timing

Both Evening Primrose Oil and Krill Oil may affect blood clotting through different pathways. Consider monitoring for signs of increased bleeding (easy bruising, prolonged cuts) when taking both supplements together.
