Oxidative stress is a condition characterized by the imbalance of the ratio of free radicals and antioxidant enzymes produced by the host tissue.
In other words, oxidative stress is either caused by overexpression of free radicals or depletion of antioxidant enzymes in the body.
Some researchers suggested that oxidative stress may also arise due to the chain reaction of free radicals in which free radicals donate or intercept an electron from other stable molecules.
Long-term oxidative stress present in the body can cause protein and lipid damage and alternation of cell DNA, leading to the onset of chronic diseases, including cardiovascular disease, diabetes, and cancer.

In some cases, this reaction also is caused long-term accumulation of toxic substances in the body, such as lead, cadmium, mercury, and arsenic.
There is no single cause of oxidative stress. Some researchers suggested that a number of factors can facilitate the onset of oxidative stress, including cigarette smoke, and oxidative burst from activated macrophages, particularly, the free radicals chain reaction.
Sadly, a prolonged period of oxidative stress present in the human body can cause oxidative damage to biomolecules, (lipids, proteins, DNA) and the death of healthy cells through cytotoxicity.
Certain chronic diseases are found to be associated with oxidative stress, including atherosclerosis, cancer, diabetics, rheumatoid arthritis, post-ischemic perfusion injury, myocardial
Tocopherols are phytochemicals of which many have vitamin E activity, belonging to the group of Lipids, found abundantly in butter, egg yolk, milk fat, some vegetable, seed or nut oils, etc.
On finding a potential phytochemical for the treatment of diseases associated with oxidative stress, researchers examined the curative efficacy of L-Ascorbic acid (L-AA) and α-Tocopherol (α-TOC) against Arsenic trioxide (As2O3) toxicity using immortalized human Chang liver cells.

* L-AA (100 µM) and α-TOC (50 µM) recovered As2O3 (10 µM) cytotoxicity.
* As2O3 treatment showed an increase in lipid peroxidation and depletion in antioxidant status, mitochondrial transmembrane potential, and values of total antioxidant capacity.
Based on the results, researchers said, "substantiate the effect of antioxidant vitamins in protecting the hepatocytes from oxidative stress which may be attributed through Nrf2 (Nuclear factor erythroid 2-related factor 2) mediated upregulation of Bcl2 (B-cell lymphoma 2) expression".
Taken altogether, tocopherols may be considered a supplement for reducing the risk of liver oxidative stress, pending the confirmation of the larger sample size and multicenter human study.
Intake of tocopherols in the form of supplements should be taken with extreme care to prevent overdose and acute liver toxicity.
