Below is a snapshot of some supporting research: In one very small study on five people with mild to moderate Parkinsons disease and three controls, a high dose of NAC (a total of 6,000 mg/day taken orally which diminished the bioavailability of the dose) for a period of 4 weeks led to an increase of cysteine levels and antioxidant measures (GSH/GSSGa ratio of the reduced to oxidized glutathione which relates to oxidative stress with higher ratio levels associated with healthier cellsand catalase), but it did not demonstrate any improvement in the oxidative stress measurements (4HNE and MDA) nor did it increase the level of glutathione in the brains

A raised GSSG level signals oxidative stress which is associated with chronic diseases, such as diabetes, cancer, heart problems, and even certain diseases of the nervous system
