I have on/off times which I find difficult to govern. I have been following this thread with interest, therefore. There is little reliable information available in our small town (pop. 30,000). In an area of the Web on alternative medecine, I saw a claim that the amino acids L-TYROSINE and L-GLUTAMATE were beneficial to PD sufferers, in that they aided the uptake of l-dopa. In view of your comments about "... large neutral amino acids...", could you comment on this. (I know nothing of the subject.) Jim
