Your cells contain glutathione, which is a substance made from three amino acids: cysteine, glutamate, and glycine.

Glutathione acts as an important antioxidant in your body. That means it helps combat free radicals, molecules that can damage your body’s cells.

Glutathione plays a role in many chemical reactions in your body. It also helps detoxify chemicals, including some that your body creates naturally, as well as pollutants and drugs.
