Antioxidant News and Research

RSS

Antioxidants are substances that protect cells from the damage caused by free radicals (unstable molecules made by the process of oxidation during normal metabolism). Free radicals may play a part in cancer, heart disease, stroke, and other diseases of aging. Antioxidants include beta-carotene, lycopene, vitamins A, C, and E, and other natural and manufactured substances.

Study Reveals the "Black Box" of Protein Quality Control in the ER

Over the past few years, Kivanç Birsoy of Rockefeller University and his colleagues in the Laboratory of Metabolic Regulation and Genetics have uncovered amazing information about the antioxidant glutathione, which has numerous vital functions in the body, including eliminating free radicals and repairing cellular damage.

Oxidative Stress May Hold Clues to the Origins of Repetitive Behaviors

Abnormal repetitive behaviors in mice are strongly linked to multiple biomarkers of oxidative stress, which occurs when antioxidants cannot counteract the effects of harmful molecules in the body, according to a study published November 5, 2025, in the open-access journal PLOS One by Kendall Coden and Dr. Joseph Garner of Stanford University, U.S.

Hidden Role of Biliverdin Reductase A in Fighting Oxidative Damage

According to a new study from Johns Hopkins Medicine, the enzyme biliverdin reductase A (BVRA) protects neurons directly from oxidative stress, regardless of whether it produces the yellow pigment bilirubin.

Study Unveils the Complete Biosynthetic Loop Regulating Tannin Production in Strawberries

Hydrolyzable tannins (HTs), including gallotannins and ellagitannins, are essential polyphenolic compounds that influence fruit taste, antioxidant capacity, and stress tolerance. Although condensed tannin biosynthesis has been well studied, the enzymatic processes governing HT formation remain unclear.
