Resveratrol improves post-meal glucose levels in pilot study.

The results of a study of resveratrol supplementation published in the Journal of Gerontology: Biological Sciences indicate a benefit for resveratrol supplementation in men and women with impaired glucose tolerance.*

Researchers at Albert Einstein College of Medicine enrolled ten overweight subjects aged 65 and older with elevated fasting and two-hour glucose. Participants were randomized to 1.0, 1.5 or 2 grams resveratrol per day, to be consumed for four weeks. Fasting and postmeal glucose, as well as insulin levels, were measured before and at the end of the treatment period, and endothelial function was assessed during the meal test at the beginning and end of the study.

While fasting glucose levels remained unchanged after four weeks, peak postmeal glucose levels decreased by an average of 19 mg/dL and three hour glucose levels also declined. Participants additionally experienced improved insulin sensitivity and a trend toward better postmeal endothelial function.
