Life Extension Glutathione 500 mg Capsules, Antioxidant, 60 Capsules

What the brand says

Glutathione is the body’s master antioxidant. Your body makes glutathione from three amino acids: cysteine, glycine and glutamate. Glutathione’s main job is to quench free radicals, compounds that impact cellular function. Glutathione helps regenerate other antioxidants, acts as a cofactor for many enzymes, and is involved in the metabolism of certain compounds that can increase free radical activity. Our high-potency formula delivers 500 mg of the active form of glutathione (reduced glutathione).
