I have Parkinson's...been recommended for DBS...doing a lot of questioning, research...came across this ... "you can prevent and stop the progress of Parkinson's if the right measures are taken soon enough. The amino acid L-cysteine gets converted in the brain to the amino acid glutathione...which is a powerful protector of the cells that become damaged in Parkinson's and in Dementia. For years now, I've been giving my Parkinson's patients L-cysteine. When it is given in high enough doses, it stops the progression of the disease.
The other nutrient I use is melatonin. Studies in animals that were given a drug that causes Parkinson's show that if these animals are given melatonin in high enough does, they don't get the disease. The dose of L-cysteine I use is 1,000 mg twice a day. The melatonin dose is 120 mg taken about 45 minutes before bedtime. Both of these natural substances are safe and completely without side effects at these doses." Dr. XXXXXXX Schallenberger
