i just re-read my sentence about b-complex. it looks ambiguous in hindsight. i meant, don't let the b6 get too high. but as i said, you're not likely in danger with a b12 down at 40, omg.
be careful when they tell you things are "normal"... do you know what part of the range you're in for iron?
does your vitamin water specify any mineral content also?
sounds like you're on the right track in a lot of ways, but you want to figure out WHY the b12 was so low for sure. was it just that you didn't consume enough, or some other issue (doesn't sound at all like you didn't consume enough to me). the neuro sounds a bit wonky eh.
elevated white blood cells in the CSF... that's your IgG et al isn't it ... i had that too and it normally means there's probably, but not definitely, oligoclonal bands (which suggest inflammation of the central nervous system). but they have to wait longer for that test to come back at my hospital, so i was on tenterhooks for a couple days there til they said yep, you've got 'em. here's an abstract:
Oligoclonal bands measured in unconcentrated cerebrospinal fluid and other biochemical parameters in multiple sclerosis.Kurzepa J, Nastaj M, Mitosek-Szewczyk K, Bartosik-Psujek H, Stelmasiak Z.

Various biochemical parameters of cerebrospinal fluid (CSF) obtained from sixty-nine patients with RRMS (relapse-remitting MS) were compared in this study. Total protein level, white blood cells (WBC) count and presence of oligoclonal bands (OB) in CSF were examined. The presence of OB in unconcentrated CSF using an isoelectrofocusing assay on agarose gels and silver staining were measured in 72 percent of patients. The average CSF total protein level measured by Lowry assay was 269 mg/l (range from 61 to 712 mg/l). The mean level of white blood cells (WBC) was higher than in general population and it was 12 cells/microl. (jimmylegs edit: general pop 0-5 cells/microl) We found an increased level of WBC count among patients with the presence of oligoclonal bands in CSF.
