Red Wine Benefits in a Pill
An ingredient in red wine—resveratrol—has been shown to have a number of health benefits, especially at high doses. In fact, according to a recent study, a daily dose equal to about 1,000 bottles of wine could slow the progression of Alzheimer’s. Since this ingredient is present in very low doses in wine, researchers are trying to develop a concentrated, high-potency form of resveratrol.
So far, side effects have been a major problem. High doses of resveratrol can cause nausea, vomiting, and diarrhea and a clinical trial to study resveratrol pills was stopped in 2010 because kidney problems developed in some participants.
Now some scientists are trying to increase the potency of the substance at more moderate doses, and combine it with other ingredients found in red wine. Others are trying to develop a synthetic version of resveratrol. Health professionals do not recommend drinking red wine or taking supplements—the risks of alcohol consumption outweigh the benefits and there is no evidence that supplements are beneficial.
