The Effect of the Oral Administration of Leucine on Endothelial Function, Glucose and Insulin Concentrations in Healthy Subjects

Objective The aim of our study was to investigate the potential differential effect of hyperglycaemia and hyperinsulinaemia induced by glucose infusion alone and in combination with leucine consumption on endothelial function in healthy individuals. Methods Ten male volunteers were examined in random order twice. In one visit, they consumed 250 ml water (baseline) and 30 min later glucose was infused iv. In the other visit, they consumed 250 ml...
