Resveratrol is a natural compound found in the skin of grapes, blueberries, raspberries, and mulberries. Plants make it to protect themselves from stress and germs. These same antioxidant and anti-inflammatory properties may help protect human tissues as well.
At an American Heart Association meeting (Minneapolis, 2017), researchers reported that resveratrol supplementation reduced arterial stiffness in people with type 2 diabetes, suggesting potential improvement in vascular flexibility and lower cardiovascular risk. Dr. Naomi Hamburg of Boston University, who led the study, noted that while more research is needed, the findings support resveratrol’s role in vascular health.
Additional research published in Nutrition Research (2012 Jul; 32(7):537–541) tested 250 mg/day of resveratrol for three months in patients with type 2 diabetes. Compared with controls, the supplemented group showed lower HbA1c, systolic blood pressure, and total cholesterol, indicating improved metabolic control and reduced cardiovascular risk factors.
