"Low glutathione levels have been associated with neurodegenerative diseases such as
MS (Multiple Sclerosis), ALS (Lou Gehrig's disease), Alzheimer's disease and Parkinson's disease, among others." The Lancet 344: 796-798, 1994
Strange how PSP and CBD are missing from this list and have to listed 'among others'.
Still I have started my wife (CBD) on 500mg of glutathione daily and taking it myself too, prevention better than cure.
