Hi! Bob:
To get more info on SAM-e and PD, do the following:
On the internet please go the site of PubMed
Search for: S-adenosyl-methionine and Parkinson's disease
You shall run into several articles; some are by Lamango, NS.
Also read an article by Kathrynne Halden in askthedietitian column on
13th or 14th of July 2002. According to her it is n knwn that SAM-e or
SAMMY of SAM (S-adenosyl-methionine) is good or bad fr PD patients.
Good Luck!
Raj

> > molecule present in cells throughout the human body. It contains a group
> > of atoms called a "methyl group." It's importance lies in the fact that
> > it can donate this methyl group to another molecule, to form a new
> > substance, often an enzyme. This donation is called "methylation," and
it
