Resveratrol is a chemical found in red wine, red grape skins, purple grape juice, mulberries, and in smaller amounts in peanuts. It is used as a medicine.
People use resveratrol for “hardening of the arteries” (atherosclerosis), lowering “bad” (LDL) cholesterol levels, increasing “good” (HDL) cholesterol levels, and preventing cancer.
Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, Ineffective, and Insufficient Evidence to Rate.
The effectiveness ratings for RESVERATROL are as follows:
More evidence is needed to rate resveratrol for these uses.
Resveratrol might expand blood vessels and reduce the activity of cells important in blood clotting. Some research suggests that resveratrol has weak estrogen (a female hormone) effects. It may also decrease pain and swelling (inflammation).
Resveratrol is LIKELY SAFE when used in the amounts found in foods, and when taken by mouth in doses up to 250 mg daily for up to 3 months. Higher doses of up to 900 mg have been taken for up to 2 days. Resveratrol has also been applied to the skin safely for up to 30 days.
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 during pregnancy and breast-feeding.
Bleeding disorders: Resveratrol might slow blood clotting. In theory, resveratrol might 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.
Surgery: Resveratrol might increase the risk of bleeding during and after surgery. Stop using resveratrol at least 2 weeks before a scheduled surgery.
Interaction Rating = Moderate Be cautious with this combination.
Talk with your health provider.
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 chlorzoxazone, theophylline, and bufuralol.
Some medications changed by the liver include clozapine (Clozaril), cyclobenzaprine (Flexeril), fluvoxamine (Luvox), haloperidol (Haldol), imipramine (Tofranil), mexiletine (Mexitil), olanzapine (Zyprexa), pentazocine (Talwin), propranolol (Inderal), tacrine (Cognex), zileuton (Zyflo), zolmitriptan (Zomig), and others.
Some medications changed by the liver include theophylline, omeprazole, clozapine, progesterone, lansoprazole, flutamide, oxaliplatin, erlotinib, and caffeine.
Some medications changed by the liver include amitriptyline (Elavil), carisoprodol (Soma), citalopram (Celexa), diazepam (Valium), lansoprazole (Prevacid), omeprazole (Prilosec), phenytoin (Dilantin), warfarin, and many others.
Some medications changed by the liver include acetaminophen, chlorzoxazone (Parafon Forte), ethanol, theophylline, and anesthetics such as enflurane (Ethrane), halothane (Fluothane), isoflurane (Forane), methoxyflurane (Penthrane).
Some medications changed by the liver include some calcium channel blockers (diltiazem, nicardipine, verapamil), chemotherapeutic agents (etoposide, paclitaxel, vinblastine, vincristine, vindesine), antifungals (ketoconazole, itraconazole), glucocorticoids, alfentanil (Alfenta), cisapride (Propulsid), fentanyl (Sublimaze), lidocaine (Xylocaine), losartan (Cozaar), fexofenadine (Allegra), midazolam (Versed), and otherslovastatin (Mevacor), ketoconazole (Nizoral), itraconazole (Sporanox), fexofenadine (Allegra), triazolam (Halcion), and many others.
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.
Resveratrol might slow blood clotting. Using it along with other herbs or supplements that might also slow blood clotting could increase the risk of bleeding or bruising in some people. These herbs include angelica, clove, danshen, feverfew, garlic, ginger, ginkgo, ginseng Panax, horse chestnut, red clover, turmeric, and others.
There are no known interactions with foods.
The appropriate dose of resveratrol depends on several factors such as the user's age, health, and several other conditions.
