In contrast, extensive research has been conducted on the chemotherapeutic activity of resveratrol in in vitro and in vivo models, and many of these findings implicate the potential utility of resveratrol in a clinical setting. Additionally, resveratrol improved flow-mediated dilation (Fmd), which when impaired causes endothelial dysfunction. It is therefore, important that resveratrol be investigated further for the prophylactic treatment of osteoarthritis in humans and companion animals. The authors measured insulin sensitivity by glucose infusion rate (Gir) and the amount of ros within skeletal muscle of trained subjects (Previously untrained) in the presence or absence of antioxidant supplementation with vitamin e and vitamin c.
