Overview InformationGlutathione is a substance produced naturally by the liver. It is also found in fruits, vegetables, and meats.
People take glutathione by mouth for treating cataracts and glaucoma, preventing aging, treating or preventing alcoholism, asthma, cancer, heart disease (atherosclerosis and high cholesterol), hepatitis, liver disease, diseases that weaken the body’s defense system (including AIDS and chronic fatigue syndrome), memory loss, Alzheimer’s disease, osteoarthritis, and Parkinson’s disease. Glutathione is also used for maintaining the body’s defense system (immune system) and fighting metal and drug poisoning.
Glutathione is breathed in (inhaled) for treating lung diseases, including idiopathic pulmonary fibrosis, cystic fibrosis, and lung disease in people with HIV disease.
Healthcare providers give glutathione as a shot (by injection into the muscle) for preventing poisonous side effects of cancer treatment (chemotherapy) and for treating the inability to father a child (male infertility).
Healthcare providers also give glutathione intravenously (by injection into the vein, by IV) for preventing “tired blood” (anemia) in kidney patients undergoing hemodialysis treatment, preventing kidney problems after heart bypass surgery, treating Parkinson’s disease, improving blood flow and decreasing clotting in individuals with “hardening of the arteries” (atherosclerosis), treating diabetes, and preventing toxic side effects of chemotherapy.
How does it work?Glutathione is involved in many processes in the body, including tissue building and repair, making chemicals and proteins needed in the body, and for the immune system.
Uses & Effectiveness
Possibly Effective for
- Reducing side effects of chemotherapy treatments for cancer.
Insufficient Evidence for
- Build up of fat in the liver in people who drink little or no alcohol (nonalcoholic fatty liver disease or NAFLD). Early research shows that taking glutathione by mouth for 4 months might reduce blood levels of a marker of liver damage called ALT and triglyceride levels in people with liver disease not related to alcohol. However, glutathione does not appear to improve liver stiffness in people with this disease.
- Parkinson disease. Early research shows that taking glutathione as a nasal spray three times daily for 3 months does not appear to improve symptoms of Parkinson disease.
- A group of eye disorders that can lead to vision loss (glaucoma).
- Alcohol use disorder.
- Alzheimer disease.
- Athletic performance.
- Chronic fatigue syndrome (CFS).
- Conditions in a man that prevent him from getting a woman pregnant within a year of trying to conceive (male infertility).
- Cystic fibrosis.
- Decline in memory and thinking skills that occurs normally with age.
- Hardening of the arteries (atherosclerosis).
- Heart disease.
- High cholesterol.
- Lung diseases.
- Skin lightening.
- Swelling (inflammation) of the liver (hepatitis).
- Other conditions.
Side Effects & SafetyGlutathione is POSSIBLY SAFE for most adults when taken by mouth, by inhalation, or by injection into the muscle or into the veins. But the possible side effects are not known.
Special Precautions & Warnings:Pregnancy and breast-feeding: Not enough is known about the use of glutathione during pregnancy and breast-feeding. Stay on the safe side and avoid use.
Asthma: Do not inhale glutathione if you have asthma. It can increase some asthma symptoms.
We currently have no information for GLUTATHIONE Interactions.
The following doses have been studied in scientific research:
- Healthcare providers give glutathione intravenously (by IV) along with chemical cancer treatments (chemotherapy) to reduce some of the unwanted side effects of the chemotherapy.
