Can You Take Grape Seed Extract and Korean Angelica Together?

Use extra care with this pair

The short answer

Grape Seed Extract inhibits platelet aggregation via proanthocyanidins, while Korean Angelica contains coumarins with anticoagulant properties. Taking both may amplify blood-thinning effects through different mechanisms.

How to arrange timing

Both Grape Seed Extract and Korean Angelica may affect blood clotting through different pathways. Consider monitoring for signs of increased bleeding (easy bruising, prolonged cuts) when taking both supplements together.
