help Grape Seed Extract FAQ
What are the active compounds in grape seed extract?
Grape seed extract is concentrated in oligomeric proanthocyanidin complexes, often abbreviated as OPCs. These plant compounds act as antioxidants in laboratory studies, although supplement composition varies considerably between brands.
Does grape seed extract actually lower blood pressure?
Some clinical studies and pooled analyses have found modest reductions in blood pressure, but the results are not consistent enough to replace prescribed treatment. Anyone with hypertension should discuss it with a clinician and continue medications such as ACE inhibitors unless advised otherwise.
Can grape seed extract interact with blood thinners?
Grape seed extract may affect platelet activity, so caution is sensible with warfarin, clopidogrel, aspirin or similar medicines. A pharmacist or physician should review the combination, particularly before surgery or if unusual bruising occurs.
Is grape seed extract the same as resveratrol?
No. Grape seed extract primarily supplies proanthocyanidins, while resveratrol is a different polyphenol associated mainly with grape skins and red wine.
