The effect of aqueous extract of Iranian oak (Quercus brantii) on antioxidant capacity and oxidative stress in beta-thalassemia patients: Randomized controlled trial.

Background And Aim: Frequent administration of blood in β-thalassemia patients can lead to over-loaded iron, a reduction in the levels of antioxidant activities in the body, and oxidative stress. This study was done to evaluate the antioxidant and protective effect of aqueous oak (Quercus brantii) extract supplementation on these patients.

Methods: This clinical trial was performed on 60 major β thalassemia patients dividing them into intervention and control groups.

Flaxseed Oil Supplementation Augments Antioxidant Capacity and Alleviates Oxidative Stress: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Objective: Studies have reported controversial findings regarding the flaxseed oil effect on antioxidant status biomarkers. The present meta-analysis aimed to determine the impact of flaxseed oil on the serum level of biomarkers of oxidative stress.

Methods: A systematic search was conducted up to November 2020 on PubMed, Embase, Web of Science, Scopus, and Cochrane Central Library.
