Introduction
Glutathione is a key component of two antioxidants present in the body. It also plays an important role in the removal of toxins. Physicians recommend the use of a glutathione formulation that is labeled “GSH” on supplement packaging as GSH glutathione is the only active form of the supplement.
Foods containing glutathione include avocado, watermelon, asparagus, grapefruit, potato, acorn squash, strawberries, oranges, tomatoes, cantaloupe, broccoli, okra, peaches, zucchini, and spinach.

Reported Uses
Glutathione is perhaps best known for its role in inhibiting free radical damage. It has also been researched for its potential ability to convert harmful foreign compounds like pesticides, solvents, and air pollutants into less harmful substances that can be flushed from the body. On the cellular level, glutathione may facilitate the transport of important nutrients across cell membranes while supporting the integrity of red blood cells. What’s more, glutathione may support the cells that carry out our immune responses.
Based on what researchers know about the role of glutathione in the body, a number of targeted clinical applications have been developed. Glutathione may significantly enhance quality of life and prevent liver and kidney damage in patients who are receiving chemotherapy. (1) , (2) , (3) It may also support health during radiation therapy. (4) What’s more, glutathione may improve liver function in recovering alcoholics. (5)
Glutathione deficiency has been associated with cataracts and supplementation has shown promising results. (6) A deficiency of glutathione in patients with anorexia nervosa might have an increased risk of liver damage. (7) Deficiency has also been associated with Parkinson’s disease. Researchers think glutathione may hold promise for future treatment and prevention of the disease. (8)
Because glutathione can support immune function, it has seen use in the treatment of AIDS. Results have been promising when glutathione is used in concert with AZT, a common AIDS treatment. (9) Studies have also suggested that glutathione may treat respiratory infections in children. (10)
