Week 4-8: Progressive improvement for responders
Classical homocystinuria: from cystathionine beta-synthase deficiency to novel enzyme therapies
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
Its short half-life, however, required it to be injected several times a day, which limited its appeal as a drug, and the company ran out of funding
Poor sleep, high stress, and smoking all accelerate glutathione depletion, making consistent lifestyle habits as important as the infusions themselves
