Not sure what happened to the link but you can search for "folic acid and parkinson's disease" to find the study.

Thanks for this link. I am surprised I never saw this before. Sometimes you just miss stuff.

Also I did some reading on folate and it doesn't cross the blood brain barrier till your body processes it into L-methylfolate .. but the good news is that L-methylfolate, while it might not be easy to find in a store, it is easy to find via the Internet. It does cross the BBB.

I have mine on the way.

The Vitamin Shoppe in my area has l-methylfolate. They have it by Solgar, Soloray and Doctors Best. I purchased 60 tablets at 1000 milligrams $13.00 so it is not expensive.

Make sure it says L 5 methylfolate or else it's probably the cheap R form, no good for our purposes. Chirality matters. See http://en.m.wikipedia.org/wiki/Chirality_(chemistry)

I think you might mean micrograms, abbreviated as mcg. Not trying to rag on you, just want to make sure people search for the right stuff.

1000 micrograms = 1mg. I use Metabolic Maintenance 10mg L-methylfolate (5-MTHF).

Yes, you are correct. Thanks for catching that. It is 1000 mcg.

Thanks for this posting BlackFeather!

It has only been 4 days but I could tell my tremors are decreasing from methylfolate (B9). I'm not sure I felt much more than reduced tremor except to say that I felt "smoother".

This morning I tested for tremor (just holding my hands out looking for tremor) and I couldn't believe it .. zero tremor at first. I have had this little tremor thing for like a decade or more and it's getting under control!

I've been taking 3 mg a day, spread thru the day. Next, I'm gonna step up to 5 mg and see how it goes.
