I was experiencing mild neurological symptoms that kept getting worse. After months of testing my b12 was checked in April 180 (scale 141-489) then my folic acid in June 8.3 (scale 10.4-42.4) my thryoid was also swinging hyper (Ive been hypo all of my life)
I moved back to the US and had loads of tests (celiac's, anti parietal etc) and was supplementing with pills. my b12 was 412 pg/ml by July 21st
moved again to France who is very liberal with their injection policy and I got 6 loading doses in August and 3x a week in sept.
I've also had an MRI to rule out MS, no HIV, Hep C, and taking folate, iron and a regular b vitamin
my questions, I've looked through the site and it seems that once supplementation starts there aren't any tests to determine whether or not how well my body is using b12?
should I try to change forms of b12? (here they use cyano)
is there anything else I should be testing for? my neurological symptoms have gotten worse, Ive since had a NCS that showed damage in both feet and hands, and feel numbness in my trunk. just worried I am a few weeks or less from having to quit my job...
