Can You Take Grape Seed Extract and Delta-Tocotrienol Together?

Use extra care with this pair

The short answer

Grape Seed Extract inhibits platelet aggregation via proanthocyanidins, while Delta-Tocotrienol inhibits platelet aggregation at higher doses. Taking both may amplify blood-thinning effects through different mechanisms.

How to arrange timing

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

Important context

Whether supplements suit you together also depends on dose, product formulation, health conditions, and medication use. Ask a doctor or pharmacist first if you take medication, are pregnant or breastfeeding, or have a chronic condition.
