What variations of resveratrol exist?Our top pick, what to skip, and how to read the label

Label red flags

  • Japanese knotweed listed with no trans-resveratrol amount
  • Products marketed as 'red wine in a pill' or with anti-aging promises

Check with a provider

  • Taking blood thinners or antiplatelet medicines, or having surgery soon. Resveratrol may raise bleeding risk.
  • Hormone-sensitive conditions such as breast or uterine cancer, endometriosis, or fibroids. It may act weakly like estrogen.
  • Taking medicines processed by the liver, since resveratrol can change their levels
  • Pregnancy or breastfeeding
  • In cancer treatment. Ask your oncology team before adding antioxidants.
