Rose,
One of the posters on my regular Sjogren's forum has been to see a neuro who suffers from Sjogren's herself. She advised this poster not to take Methocobalamin B12 because it could react to something in her dental fillings and cause "heavy metal or mercury, or something like that". Do you have any idea what she might have been told or any info on this actually happening? Admittedly, this poster was absorbing lots of new info and may have confused this, but I felt you would have the straight answer and maybe some research that could straighten this out.

Thanks much,
Billye
