Glutathione is an intracellular antioxidant. Glutamine, glycine, and cysteine are its primary building blocks. Nutritional deficiencies, exposure to environmental pollutants, and emotional stress can all lower the body’s glutathione levels. Age also causes a decrease in its levels. Glutathione is a powerful antioxidant that can be taken orally, applied topically, or inhaled in addition to being produced naturally by the body. You can take it orally in capsule or liquid form. In many cases, intravenous glutathione administration may be superior to oral consumption.

1. Reduction in Oxidative Stress

When free radical generation exceeds the body’s antioxidant defenses, oxidative stress develops. Excessive oxidative stress has been linked to a variety of illnesses. The list includes conditions including diabetes, cancer, and RA. By protecting cells from oxidative stress, glutathione may play a role in reducing the prevalence of disease.

 

Journal of Cancer Science and Therapy published research suggesting that low glutathione levels enhance oxidative stress, which in turn raises the risk of cancer. In addition, it was found that cancer cells with increased glutathione levels had greater antioxidant capacity and resilience to oxidative stress.

2. Reduction in Cell Damage

A lack of antioxidants, such as glutathione, may increase liver cell death. Those who don’t drink excessively are just as susceptible to developing fatty liver disease as those who do. People with alcoholic and nonalcoholic chronic fatty liver disease who take glutathione see improvements in their blood protein, enzyme, and bilirubin levels.

3. Insulin Resistance

Glutathione production declines with age. Baylor College of Medicine researchers looked at the effects of glutathione on insulin resistance and body weight in both animal and human trials. Researchers found that reduced levels of glutathione were linked to increased fat storage and decreased fat burning.

 

Within two weeks of supplementation, insulin resistance was reduced and fat was burned more efficiently in the elderly participants who had cysteine and glycine added to their diets to boost glutathione levels.

4. Helps In Peripheral Artery Disease

When plaque builds up in the arteries of the body’s periphery, a condition known as peripheral arterial disease develops. The legs are the most typical target of this condition. One study found that when subjects took glutathione, they were able to walk further without experiencing any discomfort. Glutathione or a saline solution placebo was infused intravenously twice daily for five days, and participants’ mobility was measured at the end of the study.

5. Effective Against Autoimmune Illness

Oxidative stress can be exacerbated by the chronic inflammation that characterizes autoimmune disorders. Rheumatoid arthritis, celiac disease, and lupus are all examples of autoimmune disorders. A single study suggests that relying on whether it stimulates or dampens the immune response, glutathione aids in the mitigation of oxidative stress. Autoimmune disorders frequently target the mitochondria of susceptible cells. By neutralizing free radicals, glutathione helps shield mitochondria from damage.

6. Efficient for Autism Children

Children with autism had higher amounts of oxidative damage and lower levels of glutathione in the brain, according to a number of research, including a clinical trial described in Medical Science Monitor. Autistic children are more likely to have brain harm from exposure to chemicals like mercury.

 

Children between the ages of three and thirteen participated in an eight-week research experiment using oral or transdermal doses of glutathione. Children in both groups had increased levels of cysteine, plasma sulfate, and whole-blood glutathione, but the study did not assess improvements in autistic symptoms.

7. For Healthy Skin Whitening

Glutathione’s potential skin-lightening effects have been the subject of research. Tanners are popular among the white population while brightening products are more popular among those with darker skin tones. Glutathione is currently one of the market’s most sought-after skin-lightening solutions.

 

It’s important to know the difference between melanin, eumelanin, and pheomelanin first. There are two forms of melanin, pheomelanin (which is yellowish-red) and eumelanin (which is blackish-brown), that make up the skin pigment melanin. A higher pheomelanin ratio results in lighter skin. Sunlight causes hyperpigmentation by triggering the body to produce free radicals like reactive oxygen and nitrogen species. These free radicals might hasten skin aging if antioxidants aren’t present to keep them in check. Brighter skin is the result of glutathione’s ability to convert eumelanin to pheomelanin.

8. Protection of  mitochondrial DNA (mtDNA)

There may be indicators of longevity in the body’s cells or tissues. Telomeres are used as a measure of longevity in humans and other animals. Telomeres are caps at the ends of chromosomes; the longer they are, the longer a person can expect to live.

 

Mitochondrial DNA (mtDNA) is a biomarker for aging or tissue health in cells. The levels and activity of glutathione would be indicative of mtDNA function. Low glutathione levels are linked with decreased mtDNA activity.

9. Free Radical Neutralizer

Studies in animals have shown that an excess of free radicals can cause cell death and accelerated aging. In humans, free radicals are widely believed to contribute to inflammation, which in turn can cause conditions including arthritis and neurological illnesses. In addition, free radicals cause cell death by reacting with other proteins and enzymes.

 

The harmful effects of free radicals are neutralized by antioxidants. Free radicals created in the liver during detoxification can be neutralized with the help of glutathione, a strong antioxidant. As a result, the liver is better able to continue its detoxification of toxins and metabolites without being damaged by free radicals.

10. Cofactor in Enzymes

Cofactors are chemicals or proteins that stimulate an enzyme’s function. Enzyme cofactors go by a few other names. Glutathione is a cofactor of several enzymes in addition to being an antioxidant. Reducing glutathione makes it an essential cofactor in numerous antioxidant processes. Therefore, taking glutathione supplements can boost antioxidant activity, improve cell health, and slow down or stop cell death.

11. Brain Tissues Protection

Inorganic mercury is a heavy metal that can be consumed by eating contaminated food. Mercury can enter the human body through the ingestion of shellfish and fish that contain even small amounts of the toxin methylmercury. Mercury ingested can be stored in the central nervous system. Mercury is a lipophilic inorganic metal, thus, it is easily absorbed by the brain and stays there for years.
