Glutathione has caught the fancy of many Hollywood celebrities, biohackers and longevity enthusiasts. The powerful naturally-occurring compound nicknamed the ‘master antioxidant‘ is hailed for its potential to fight oxidative stress, detoxification of the body, and even slowing down aging. Gwyneth Paltrow, who’s known for embracing controversial wellness trends has expressed her fondness for it. “I’m an early IV adopter,” she had said during an interview, adding, “Glutathione, I love to have an IV.” From liver detoxification, supporting the immune system, to boosting longevity, Glutathione can help reap many benefits. On the other hand, its deficiency can trigger fatigue, brain fog, sleep disturbances, frequent infections, and anemia. Let’s know more about it.
What is glutathione?
Glutathione is naturally produced by cells in the body and is composed of three amino acids – glutamine, glycine, and cysteine. It plays an important role in cellular function, detoxification, and immune support. The National Cancer Institute describes glutathione as a detoxifying agent that helps prevent cell damage from free radicals, unstable molecules linked to cancer and other chronic diseases.
How glutathione helps: Know its benefits
Detoxification: It helps remove toxins from the liver, making it a key player in maintaining liver health.
Boosts immunity: It strengthens the immune response and helps fight infections.
Reduces oxidative stress: By neutralizing free radicals, it may lower the risk of chronic diseases linked to inflammation and oxidative stress.
Aging and longevity: Some researchers suggest that glutathione levels decline with age, leading to poorer health outcomes. This has fueled interest in its potential anti-aging properties.
Fatty liver: A study published in BMC Gastroenterology found that orally administered glutathione helps people with nonalcoholic fatty liver disease, in combination with other lifestyle changes. In this study, glutathione was given in supplement form at a dose of 300 milligrams per day for four months.
Helps with diabetes: According to a study published in Applied Physiology, Nutrition, and Metabolism, obese men who had type 2 diabetes and some who did not, benefitted from oral glutathione supplementation as their insulin resistance improved.
Glutathione deficiency can be caused by factors such as poor nutrition, environmental toxins, chronic stress, and aging. Some conditions linked to low glutathione include cancer, HIV/AIDS, type 2 diabetes, hepatitis, and Parkinson’s disease.
Signs of glutathione deficiency:
Fatigue
Brain fog
Sleep disturbances
Frequent infections
Anemia
Loss of coordination or seizures
How to take glutathione
Glutathione is available in various forms, but its effectiveness depends on the method of administration:
Oral supplements: While readily available in capsule and liquid form, oral glutathione is believed to be broken down by stomach enzymes, limiting its absorption.
Intravenous (IV) therapy: IV glutathione is a popular option among celebrities, including Gwyneth Paltrow, who has publicly endorsed it. IV administration delivers glutathione directly into the bloodstream, bypassing digestion.
Injectable glutathione: In some cases, individuals have purchased glutathione vials online for self-injection—a practice that raises safety concerns due to the risk of contamination.
Topical and inhalation forms: Some companies are exploring transdermal applications, though their efficacy remains under study.
Glutathione for skin lightening
In some regions, especially in Asia, glutathione injections are used for skin lightening. However, scientific evidence supporting this effect is limited, and regulatory agencies like the FDA in the Philippines have warned against its potential toxicity to the kidneys, liver, and nervous system.
Can it help with weight loss?
Emerging research indicates that higher glutathione levels may be associated with weight loss in individuals following a healthy diet. However, it remains unclear whether supplementation directly leads to fat loss.
Natural ways to boost glutathione levels
Rather than relying on supplements, experts recommend supporting natural glutathione production by consuming glutathione-rich foods such as garlic, broccoli, asparagus, avocado, and spinach.
