Natural sources of resveratrol
Resveratrol occurs naturally in the skins of red and dark grapes, in red wine, and in blueberries, raspberries, bilberries, and pomegranates, as well as in some nuts, such as peanuts. It's also found in the roots of Japanese knotweed (Polygonum cuspidatum), a common source for food supplements. Resveratrol is most often taken in capsule, tablet, or liquid form.
Recommended daily dose of resveratrol
There's no precisely established daily allowance for resveratrol, but supplement doses for adults typically range from 100 to 500 mg per day. The right dose can vary depending on individual needs and health status.
Possible side effects of resveratrol and interactions with medications
Resveratrol is generally well tolerated, but excessive doses can cause headaches, digestive upset, or skin rashes. It can also affect how some blood-thinning medications work, so it's important to talk to your doctor before taking resveratrol supplements if you're on this type of medication.
