Glutathione is a substance made from the amino acids glycine, cysteine, and glutamic acid. It is produced by the liver and involved in many body processes.

Glutathione is involved in tissue building and repair, making chemicals and proteins needed in the body, and in immune system function.

People take glutathione for aging, alcohol use disorder, liver disease, heart disease, and many other conditions, but there is no good scientific evidence to support these uses.
