Grape skin extract concentrates polyphenols from the outer peel of grapes, especially resveratrol and anthocyanins. It delivers a higher dose of these compounds than whole grape or seed products and is often standardized for antioxidant activity.
People use it to support cardiovascular health through antioxidant and circulation friendly mechanisms. The extract can also help maintain blood pressure and cholesterol levels that are already in the normal range.
Take the extract with a meal to boost absorption of its fat soluble components. Many formulas are built for once daily use, but stick to the label directions.
Cautions apply. Resveratrol can slow blood clotting, so avoid pairing it with anticoagulants like warfarin or aspirin and stop before surgery. It may lower blood pressure and could amplify the effects of antihypertensive drugs. Safety data during pregnancy and breastfeeding are insufficient.
