Resveratrol Supplements: Side Effects and Benefits
Resveratrol Supplements: Side Effects and Benefits
Because there have been very few studies conducted on resveratrol in humans, doctors still can't confirm any benefits, and they don't know what effects these supplements might have on people over the long term. So far, studies have not discovered any severe side effects, even when resveratrol is taken in large doses. However, resveratrol supplements might interact with blood thinners such as warfarin (Coumadin), and nonsteroidal anti-inflammatory medications such as aspirin and ibuprofen, increasing the risk for bleeding.
Like other supplements, resveratrol isn't regulated by the FDA, so it's difficult for consumers to know exactly what they're getting when they buy a bottle, or whether the product is actually effective. There also isn't any specific dosage recommendation, and dosages can vary from supplement to supplement.
The dosages in most resveratrol supplements are typically far lower than the amounts that have been shown beneficial in research studies. Most supplements contain 250 to 500 milligrams of resveratrol. To get the equivalent dose used in some animal studies, people would have to consume 2 grams of resveratrol (2,000 milligrams) or more a day.
The bottom line: Until more high-quality research is available, experts do not recommend resveratrol supplements for antiaging or disease prevention.
