Resveratrol has genuine research interest for cardiovascular markers and longevity-related cellular pathways, though it’s worth knowing human evidence remains considerably less robust than the laboratory findings behind its “French Paradox” reputation. For the full, honest evidence picture, see our complete guide to Resveratrol. Below you’ll find our picks, chosen for trans-resveratrol content and quality certification.

Choosing a Resveratrol Supplement
Look for “trans-resveratrol” specifically, the active form used in most research, ideally at 98% purity or higher — most supplements actually use Japanese knotweed as the raw material, not grapes, since it yields a more concentrated, consistent source. A reasonable starting range is 100-250mg daily. Resveratrol has mild blood-thinning properties, so speak to your GP before starting if you take blood-thinning medication, are pregnant or breastfeeding, or have surgery scheduled. Our full guide covers the cardiovascular and longevity research in complete, honest detail — including where it’s genuinely promising and where it’s still unproven.
