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.

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.
