Wow, thanks mrsD, that is a lot of info.!

I'm going to the iherb.com site asap to order the methyl B-12. It looks like the B-12 range on my lab report is 180 - 914.

I was surprised to see some of the other medications that I have been taking could be considered as factors in my B-12 level. I was on Tagamet for several years (hiatel hernia) and have been on pantoprazole (protonix) for severe heartburn the last 8 years. I have also been diagnosed with and treated for depression on and off for the last 20 years, currently on sertraline (zoloft).

Thank you for answering me so quickly.
