Intravenous Glutathione has been administered safely to thousands of patients. It is not well absorbed orally and probably has marginal absorption transdermal or when applied to the skin. Glutathione is a potent antioxidant and has been used successfully as an adjunct for therapy in diseases of the nervous system, including Parkinsonism and Peripheral Neuropathy. Glutathione is the major antioxidant in the brain and is the best antioxidant within the cell itself. It is believed that supplements like N-acetyl-L-cysteine, niacin, selenium, and B12 help the body make its own glutathione. Nutrients that may help regenerate GTH include vitamin C, alpha-lipoic acid, and coenzyme Q-10.

Chronically ill patients and many of those who have various neurological diseases have responded to intravenous glutathione (GTH). Infusions are usually given weekly for three to four weeks to see if there is a favorable response. Obviously, this type of therapy cannot be guarantied, however, many have found this therapy well worth the time and low expense specifically when compared with conventional therapies.
