May Increase Insulin Sensitivity

At least in animal research, resveratrol has been demonstrated to provide a number of advantages for diabetes. These advantages include improving insulin sensitivity and avoiding diabetic complications. Resveratrol may inhibit a certain enzyme from converting glucose into sorbitol, sugar alcohol, which is one explanation for how it functions. In diabetics, sorbitol overproduction can lead to oxidative stress, which can harm cells.

People with diabetes may potentially benefit from resveratrol more than those without the disease. In one experiment on animals, red wine and resveratrol were actually more potent antioxidants in diabetic rats than in control rats. The substance, according to researchers, may one day be used to treat diabetes and its consequences, but further study is required.
