Endotoxemia, characterized by systemic inflammation, is a major cause of acute kidney injury. In this work, Sprague-Dawley male rats, pretreated for 4 days with control diet or with diets supplemented with 20 (low-level, LLE) or 80 (high-level, HLE) mg (−)-epicatechin (EC)/kg of body weight/day, were challenged with bacterial lipopolysaccharide (LPS) (i.p. 4 mg/kg BW) and sacrificed 6 h post LPS administration. In LPS-treated endotoxemic animals, plasma GPT, GOT and LDH levels were slightly or non-affected; nitric oxide (NO) levels in blood, measured by EPR, increased significantly, and HLE avoided 41% (p
