“Dr. David Perlmutter, a board certified neurologist from Naples, Florida, started using intravenous glutathione in 1998 for his Parkinson’s patients after he did extensive research on Parkinson’s disease and effects of supplemental glutathione on improving the symptoms of Parkinson’s disease. He is the pioneer in using intravenous glutathione in the treatment of Parkinson’s disease. His research opened new doors in the treatment of Parkinson’s disease and other neurodegenerative diseases. Dr. Perlmutter has successfully used intravenous glutathione in patients with significant improvement in the symptoms. Although glutathione treatment cannot prevent the occurrence of symptoms, it significantly slows down the occurrence of symptoms with improvement in the existing symptoms.
Glutathione supplements do not directly raise the dopamine levels in the brain, instead they improve the efficiency of dopamine in the brain and also increase the sensitivity to dopamine and serotonin” (from the article Glutathione and Parkinson’s Disease by Zina Kroner).
