Called “the mother of all antioxidants,” glutathione is the first line of defense against oxidative stress. It neutralizes free radicals, increases cellular function, and promotes cellular turnover.

Glutathione is a powerful antioxidant produced naturally by the body, composed of three amino acids: cysteine, glutamine, and glycine.

Glutathione is an essential molecule required for detoxification. It acts by removing harmful oxygen-containing molecules, which include peroxide and superoxide anions. Glutathione also plays an important role in a healthy immune system by supporting T-cell function. The liver uses glutathione for digestion by detoxifying fats before the gallbladder emits bile.

Glutathione is best known for repairing damaged cells in your body. It may help ward off a variety of diseases, such as neurological disorders, liver disease, certain heart conditions, autoimmune disorders, respiratory diseases, and other medical conditions.
