Thanks to Mrsl D. for her info that those with FM have low levels of B12 in their spinal cord. My level is 450. Looks like that is on the low side. I am taking 5mg of methyl sub lingual for about a year now since that test. I am due for another test soon.
Just wondering - maybe my level should be a lot higher because of the fibro. I read somewhere that some people have levels of 800-1,000.
Is there an optimal level for FM and how do you know that you are really getting it into your spinal cord?
