I came across following good article which mentions Dopavite. Dopavite main constituent is The L-dopa precursor L-tyrosine.
It seemed to me that the whey may be a good alternative source for L-tyrosine. Additionally the whey is a source for cystein which is a precursor for the vital glutathion, the antioxidant which mice research claim use for anti-PD.
Two reasons for taking the Whey! Any opinions??

“Nutrients
Nutrients have been used in clinical studies and are widely used by people with Parkinson's disease in order to partially treat Parkinson's disease or slow down its deterioration. The L-dopa precursor L-tyrosine was shown to relieve an average of 70% of symptoms.[25] Ferrous iron, the essential cofactor for L-dopa biosynthesis was shown to relieve between 10% and 60% of symptoms in 110 out of 110 patients.[26] [27] Another complementary approach is Dopavite, a nutritional supplement which contains both of these substances and all the other nutrients required for dopamine formation. However, the efficacy of this nutritional supplement has not been validated in clinical trials.

Parts of that writing style seem very familiar. It is a good article though.

what is your opinion of the whey as precurser for Glutathion and L-dopa? and if so, how much daily?

As I understand it, there is a problem with whey when it is processed in a particular manner that alters the proteins. The result is that glutamic acid is created and that is a potent excitotoxin. Dr. Blaylock, who literally wrote the book, advises against it when labeled as "whey protein concentrate.'

A site worth visiting is http://www.rtnc411.org/tlinks.html

The idea of certain proteins being altered by heat processing is particularly interesting to me because I have developed a heck of a sensitivity to such over the last couple of years. It has gotten to the point that if I get a hit of MSG then it is as if my meds have completely stopped working for four to six hours. It comes on in about 10 to 20 minutes.

One of the things that does it is the new (in the US but common in Europe) "ultra high temperature" pastuerizing of milk. Ironically, organic milk is usually done that way for a longer shelf life.

I just remembered- there was something I ran across about N-acetyl-cysteine being a safe way to boost glutathione. Try medline on it.

But why not take a product that contains all the necessary constituents to make l-dopa in one place, rather than searching around for the individual components?

At one point it was thought that I might have hemachromatosis as well as PD which necessitated avoiding dietary iron. I tried to make up my intake of all the other constituents of L-dopa and it proved very difficult to get the right levels, not too little of one thing or too much of another, especially without taking a lot of individual pills.

The constituents are such common ones that it seems like it would be an easy task, but it is not, even with the WWW as an open market place for the purchase of almost anything.

Dear Muireann:
I don't trust expensive products with no research I know of to back them up. I take a dozen supplements .. each of which is backed up with load of sceintific reesearch even if on mice!
