B12 Overdose Research
I would like to mention that I have found your site extremely helpful.
I would like to bring your attention to this forum thread where the author is compiling a lot of data from research materials to see if there is any risk of an overdose of B12:

P.S. I didn't find any form-field to submit my email address without publishing it publicly in the comment itself.
P.P.S. I found it only after hitting the submission button and editing the text. An early-heads up note on the comment letting users know that the email box will be visible later would help prevent this confusion to others.
