Is Grape Seed Extract Safe?
Many people may wonder if grape seed extract is safe. It's best to consult your healthcare provider before using this dietary supplement if you have a bleeding disorder, have any chronic or severe medical condition, or are pregnant or breastfeeding. Discussing grape seed extract safety warnings and precautions with your healthcare provider beforehand can help minimize risks.
Grape seed extract is a popular dietary supplement, claimed to be beneficial for a variety of different uses. You should talk with your healthcare provider prior to taking it if you:
- Have a bleeding disorder
- Have any chronic or severe medical condition
- Have any allergies, including allergies to foods, dyes, or preservatives
- Are pregnant or thinking of becoming pregnant
- Are breastfeeding.
You should also be sure to tell your healthcare provider about all other medicines you are taking, including prescription and non-prescription medicines, vitamins, and herbal supplements.
Warnings and precautions to be aware of concerning the safety of grape seed extract include the following:
- Theoretically, grape seed extract could increase the risk of bleeding, including dangerous internal bleeding. This risk is probably most significant for people with a bleeding disorder or who take "blood thinner" medications (see Grape Seed Extract Drug Interactions).
- As dietary supplements or food products, grape seed extract products are not as closely regulated as prescription and non-prescription drugs. They can be marketed without any proof that they are either safe or effective. Do not assume that just because a product is sold or advertised in the United States that it is automatically safe or effective. Be sure to look for grape seed extract products from a reputable manufacturer. Your pharmacist is a good resource for information about which manufacturers are most reputable.
- If you have a chronic or severe medical condition, it is always a good idea to check with your healthcare provider before taking any medication or supplement, including grape seed extract.
- It is not clear if grape seed extract is safe for pregnant or breastfeeding women (see Grape Seed Extract and Pregnancy and Grape Seed Extract and Breastfeeding).
