There seems to be a lot of conflicting information on the net. I have read so much on PD that I am overwhelmed by it all. I take 500mg 3 times a day, and it does help with the tremors. I just want to make sure I am not hurting myself with L-tyrosine. I have TOS, RSD and now PD. The VA treats me for all my health needs, but they do not know about natural meds. Any help would be appreciated, and thanks for reading my post. Stephen
