When taken by mouth: People often consume resveratrol in small amounts in foods. Resveratrol supplements are possibly safe when taken by mouth in doses up to 1500 mg daily for up to 3 months. Higher doses of up to 2000-3000 mg daily have been used safely for 2-6 months. But these higher doses are more likely to cause stomach upset.
When applied to the skin: Resveratrol is possibly safe when used for up to 30 days.
When sprayed into the nose: Resveratrol is possibly safe when used for up to 4 weeks.
Special Precautions & Warnings:
Pregnancy and breast-feeding: Resveratrol is likely safe when used in amounts found in some foods. However, during pregnancy and breast-feeding, the source of resveratrol is important. Resveratrol is found in grape skins, grape juice, wine, and other food sources. Wine should not be used as a source of resveratrol when pregnant or breast-feeding.Children: People often consume resveratrol in small amounts in foods. But there isn't enough reliable information to know if it safe to take by mouth in larger amounts. Resveratrol is possibly safe in children when sprayed in the nose for up to 2 months.
Bleeding disorders: Resveratrol might slow blood clotting and increase the risk of bleeding in people with bleeding disorders.
Hormone-sensitive condition such as breast cancer, uterine cancer, ovarian cancer, endometriosis, or uterine fibroids: Resveratrol might act like estrogen. If you have any condition that might be made worse by exposure to estrogen, don't use resveratrol.

Medications changed by the liver (Cytochrome P450 3A4 (CYP3A4) substrates)
Interaction Rating=Moderate Be cautious with this combination.
Some medications are changed and broken down by the liver.
Resveratrol might decrease how quickly the liver breaks down some medications. Taking resveratrol along with some medications that are broken down by the liver can increase the effects and side effects of some medications. Before taking resveratrol, talk to your healthcare provider if you are taking any medications that are changed by the liver.
Some medications changed by the liver include lovastatin (Mevacor), ketoconazole (Nizoral), itraconazole (Sporanox), fexofenadine (Allegra), triazolam (Halcion), and many others.
Medications that slow blood clotting (Anticoagulant / Antiplatelet drugs)
Interaction Rating=Moderate Be cautious with this combination.
Resveratrol might slow blood clotting. Taking resveratrol along with medications that also slow clotting might increase the chances of bruising and bleeding.
Some medications that slow blood clotting include aspirin, clopidogrel (Plavix), diclofenac (Voltaren, Cataflam, others), ibuprofen (Advil, Motrin, others), naproxen (Anaprox, Naprosyn, others), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, warfarin (Coumadin), and others.
Herbs and supplements that might slow blood clotting: Resveratrol might slow blood clotting and increase the risk of bleeding. Taking it with other supplements with similar effects might increase the risk of bleeding in some people. Examples of supplements with this effect include garlic, ginger, ginkgo, nattokinase, and Panax ginseng.
There are no known interactions with foods.
Resveratrol has most often been used by adults in doses of 250-1000 mg by mouth daily for up to 3 months. It is also sometimes used in nasal sprays. Speak with a healthcare provider to find out what dose might be best for a specific condition.
