Oxidation response is stimulated by a disturbance in the balance between the production of reactive oxygen species and antioxidant responses, known as oxidative stress. Active species of oxygen naturally occur in aerobic cells and have both intracellular and extracellular sources.
Oxidative stress mechanisms in tissue injury. Free radical toxicity induced by xenobiotics and the subsequent detoxification by cellular enzymes (termination).. Oxidative stress reflects an imbalance between the systemic manifestation of reactive oxygen species and a biological system's ability to readily detoxify the reactive intermediates or to repair the resulting damage.

Assays for oxidative stress and antioxidant reserves are offered by at least one diagnostic company. Diagnosing antioxidative stress is currently extremely rare due to factors such as widespread unfamiliarity, lacking proper understanding in the clinical environment, and trivial modern medical training on the subject.
Chronic inflammation can lead to oxidative stress, which damages the mitochondria, potentially impairing their ability to produce energy efficiently. As mitochondrial function declines, cells may ...
Inflammation is our immune system's response to stimulus, such as an injury or infection. ... such as polyphenols as well as natural antioxidants, which help reduce oxidative damage to your ...
One compound that these beans are especially rich in is carotenoids, which can help your body fight free radicals and prevent oxidative stress damage, which in turn can help prevent a multitude of ...
Study of a rat model of premature aging found increased oxidative stress, reduced antioxidant enzyme activity and substantially greater DNA damage in the brain neocortex and hippocampus of the prematurely aged rats than in normally aging control rats. [53] The DNA damage 8-OHdG is a product of ROS interaction with DNA.
It can be a powerful antioxidant “Coconut water contains antioxidants that may help neutralize harmful free radicals in the body and protect cells from oxidative stress,” explains Olszewski.
