Resveratrol, found in grape skins, peanuts, and cranberries, has been studied in animals for its potential to aid weight loss by reducing hunger and increasing metabolism. However, its effects on humans are not yet scientifically proven, and caution should be exercised when taking it as a supplement. Red wine has the highest concentration of natural resveratrol, but its long-term effects on human health have not been studied.

Studies conducted on laboratory animals have suggested that there may be a connection between resveratrol and weight loss. Although the effect of resveratrol in humans has not been scientifically studied, there is a possibility that this enzyme could help people lose weight and improve their fitness level. Doctors aren’t sure how much resveratrol a person may need, and many advise people not to take it as a supplement, but to consume more through diet. However, the possible connection between resveratrol and weight loss has led scientists to continue experimenting with the enzyme to determine if it increases metabolism and if it is safe for humans.

Resveratrol, which can be found in grape skins, peanuts, and cranberries, is currently available as a dietary supplement, although not much research has been done on it. This enzyme is also found naturally in red wine, which has the highest concentration of natural resveratrol at approximately 15 milligrams per bottle. Although a study in human subjects has shown that it is safe to take up to 5 grams at a time, an amount much higher than that found in supplements, the long-term effects of taking even 125 milligrams a day have not been studied. Despite the potential health risks of taking an unproven supplement, many people take this supplement because they believe there is a connection between resveratrol and weight loss.

In animal test subjects, the possible connection between resveratrol and weight loss has been studied. Mice given this supplement and a high-fat diet do not tend to gain weight. Lemurs given resveratrol seem to have a hard time gaining weight, largely because they don’t consume as much food as they normally would. The study on lemurs found that the connection between resveratrol and weight loss may occur because this enzyme makes an animal feel less hungry while increasing metabolism. In mice, resveratrol can also cause the animals to exercise more frequently.

Results from animal tests to examine the connection between resveratrol and weight loss are promising. Scientists continue to examine this enzyme to determine exactly how it might affect weight loss in humans. Until human studies are complete, people should take resveratrol with caution. There is always the possibility that despite possible positive effects, the enzyme could lead to serious health complications after long-term use.
