Evolva and Northumbria University's Brain, Performance and Nutrition Research Centre have teamed up to study resveratrol on human health. As Clare Panchoo, Evolva, and Dr Emma Wightman, Northumbria University, explain, while research has shown resveratrol's benefits on blood flow, cardiovascular health and cognitive function, no research has directly examined the interrelationship with gut microbiota. Research does show consuming polyphenols, including resveratrol, can positively benefit gut microbiota, making this an area of scientific interest. We discuss the trials the collaboration will conduct to assess resveratrol's impact on the gut, while also covering the issue of trusting an ingredient supplier in clincial research and the need for transparency in ingredient supply.
