Grape Seed Extract

BCCT plans to write a summary on grape seed extract. While our summary is in development, you can visit About Herbs: Grape Seed


The About Herbs summary on Grape Seed doesn’t list any adverse reactions. However, it lists several herb-drug interactions. For more information, see the summary linked above. If you are on any medications, consult with your physician and your pharmacist for potential drug-herb interactions before taking grape seed extract as a supplement.


BCCT does not recommend therapies or doses, but only provides information for patients and providers to consider as part of a complete treatment plan. Patients should discuss therapies with their physicians, as contraindications, interactions and side effects must be evaluated.

Dosage recommendations are available from these sources:
