Healthcare providers give glutathione intravenously (by IV) along with chemical cancer treatments (chemotherapy) to reduce some of the unwanted side effects of the chemotherapy.
Glutathione 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).
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.
