Grapeseed Extract — Uses, Dosage, Side Effects & Safety

Drug class: Herbal Supplement / Antioxidant

Overview

Grapeseed extract is a dietary supplement derived from the seeds of grapes (Vitis vinifera). It is commonly used for its antioxidant properties, which help protect cells from damage caused by free radicals. People often take grapeseed extract to support cardiovascular health, reduce inflammation, and promote general wellness. The extract contains oligomeric proanthocyanidin complexes (OPCs), which are potent antioxidants. These compounds may help improve blood circulation, support healthy blood pressure, and reduce swelling. While some studies suggest benefits for heart health and chronic venous insufficiency, more research is needed to confirm its effectiveness for various conditions. Key points: Grapeseed extract is not a substitute for prescription medications. Always consult your healthcare provider before starting any new supplement, especially if you have underlying health conditions or take other medications.
