Glutathione — Uses, Dosage, Side Effects & Safety
Drug class: Antioxidant
Overview
Glutathione is a naturally occurring antioxidant found in every cell of the body. It plays a vital role in protecting cells from oxidative stress and damage caused by free radicals. In medical settings, glutathione is used as a supplement or medication to help manage conditions related to oxidative stress, such as liver disease, certain neurological disorders, and as an adjunct in chemotherapy to reduce toxicity. Glutathione works by neutralizing harmful molecules and supporting the body's detoxification processes. It is also involved in immune function and the regeneration of other antioxidants, such as vitamins C and E. Patients should know that while glutathione is available as a supplement, its effectiveness for many uses is still being studied, and it should only be used under medical supervision for specific indications.
