The effects of rutin supplement on blood pressure markers, some serum antioxidant enzymes, and quality of life in patients with type 2 diabetes mellitus compared with placebo.

Background: This trial aimed to investigate the effects of rutin supplement in type 2 diabetes mellitus (T2DM) patients.

Methods: In this trial with a double-blind and controlled design, fifty patients were randomly divided into intervention ( = 25) and control groups ( = 25) and were treated with 1 g of rutin or placebo for three months, respectively. At the baseline and end of the intervention, mean arterial pressure (MAP), heart rate (HR), pulse pressure (PP), systolic and diastolic blood pressure (SBP and DBP), serum levels of antioxidant enzymes, such as catalase (CAT), glutathione peroxidase (GPx), and superoxide dismutase (SOD) and quality of life (QOL) parameters, were evaluated.
