Why is glutathione reduced

Glutathione is found almost exclusively in its reduced form, since the enzyme that reverts it from its oxidized form, glutathione reductase, is constitutively active and inducible upon oxidative stress. In fact, the ratio of reduced glutathione to oxidized glutathione within cells is often used scientifically as a measure of cellular toxicity.

It also reduces inflammation. N-acetylcysteine is byproduct of glutathione. Glutathione is found in some foods, although cooking and pasteurization diminish its levels significantly. Its highest concentrations are in:. Glutathione contains sulfur molecules, which may be why foods high in sulfur help to boost its natural production in the body. These foods include:. Glutathione is also negatively affected by insomnia.

Getting enough rest on a regular basis can help increase levels. A diet rich in glutathione-boosting foods does not pose any risks. However, taking supplements may not be advisable for everyone. Possible side effects may include:. Its levels decrease as a result of aging, stress, and toxin exposure. Boosting glutathione may provide many health benefits, including reduction of oxidative stress. Acne surfaces during times of hormonal imbalance.

Bay leaves have been used many different ways throughout history for possible health benefits. But what does the science say? Epithelial tissues of the kidney tubules, intestinal lining and lung have substantial P activity and modest capacity to export GSH. GSH equivalents circulate in the blood predominantly as cystine, the oxidized and more stable form of cysteine.

Cells import cystine from the blood, reconvert it to cysteine likely using ascorbate as cofactor , and from it synthesize GSH. Conversely, inside the cell, GSH helps re-reduce oxidized forms of other antioxidants such as ascorbate and alpha-tocopherol. GSH is an extremely important cell protectant. It directly quenches reactive hydroxyl free radicals, other oxygen-centered free radicals, and radical centers on DNA and other biomolecules.

GSH is a primary protectant of skin, lens, cornea, and retina against radiation damage and other biochemical foundations of P detoxification in the liver, kidneys, lungs, intestinal, epithelia and other organs. GSH is the essential cofactor for many enzymes that require thiol-reducing equivalents, and helps keep redox-sensitive active sites on enzyme in the necessary reduced state. GSH and its metabolites also interface with energetics and neurotransmitter syntheses through several prominent metabolic pathways.

GSH availability down-regulates the pro-inflammatory potential of leukotrienes and other eicosanoids. Monograph provided by Alternative Medicine Review thorne. Birmingham, AL
