I did, RoyProp. Actually, it's because of your threads about B1 that I've been drawn to taking vitamin B. In fact I am still reading your posts and those of Silvestrov (among others).
Everybody is different. I take one Cenovis Mega-B tablet every night, this is an Australian brand which I find is very good, for me at least. The ingredients follow:
You are right - everybody has different biochemistry. I have MTHFR mutation that prevents processing/breaking down folic acid into a bioavailable form and therefore unprocessed folic acid might block folate receptors preventing absorption of natural folate from foods. So my only choice is methylfolate or calcium folinate for folate supplementation. MTHFR polymorphism is very common and because it slows down body detoxification I suspect that it is more prevalent in people with PD. It would be helpful to check blood homocysteine which is usually elevated (over 10) in case of MTHFR/methylation issues and is indirect indicator of MTHFR polymorphism (unless you take levodopa which also raises homocysteine).
Also, in my case B12 is better as methylcobalamin or a combination of methyl-, hydroxy- and adenosyl- cobalamin which have better bioavailability than cyanocobalamin. There is a lot of information on the internet on this subject. Dr. Ben Lynch is my methylation "guru"
i'm a firm believer in B-12 injections for better balance, longer energy reserves being maintained, and overall help with stress. Using B12 for about 30 years and you cannot overdose on B 12... more info is available on line google search on B 12.
I take B 12 once per month and take 1 1/2 cc each time. Be sure to use a 1" needle as B 12 needs to get into muscle ... I use the top of my thigh to make sure I get into muscle tissue. Most of the time it does not hurt.
I too have taken B12, but not directly for PD, albeit for the depression that comes when I was first diagnosed with PD - many of you know what I'm talking about. Depression, along with paranoia and dementia, can be caused by a deficiency of B12. These can have an effect on the brain and nervous system, which sometimes can be irreversible.
I discussed vitamins with my Neurologist a few appointments ago, and he said: "no vitamin or supplement will aid in the slowing down, stopping or, reversing of PD."
That said, I still take a multi-vitamin, a B12, and a D3 every day.
The only thing that I have discovered what does help is vigorous exercise.
