Brief Title  ICMJE Purified Anthocyanins Supplementation in Type 2 Diabetes Mellitus
Official Title  ICMJE Effect of Purified Anthocyanin on Oxidative Stress and Glycemic Control in Subjects With Type 2 Diabetes Mellitus: A Randomized, Double-Blinded, Placebo-Controlled Trial
Brief Summary Anthocyanins, the water-soluble compounds that make plants appear different colors, have been shown to prevent insulin resistance, reduce the blood glucose and oxidative stress in rodents. The purpose of our study is to evaluate a potential protective effect of purified anthocyanins supplement on type 2 diabetes mellitus patients.
Detailed Description The study was designed as a randomized, double-blind label, interventional study on patients with T2DM. The eligible Participants are randomly assigned to control and Anthocyanins supplement group. During the 12 weeks trial period,the participants were instructed to consume two anthocyanin capsules or placebo capsules twice daily (30 min after breakfast and supper).
