I am starting this thread to include some of the most useful information on B12.

This subject is very popular now, and especially on these forums.

Having a spot to refer people to answer questions, saves time and effort, since repeating over and over the same information becomes difficult.

I am going to have this thread stickied at the top of the pages here so it can be found easily.

First off, here is a link to Rose's webpage. She has been the anchor for all of us here on this subject. I haven't seen her here lately, but I suspect she reads at least.

Rose put together a wonderful collection of information and has personal reasons for wanting others to learn about the TRUTH about B12 in the body. She herself suffered for a long time with very low levels and the terrible consquences of that.

I am going to add to this thread, some of the information I've used to answer questions here about how to test for B12 problems, and how to use it correctly.

I encourage all posters who come here to learn and ask questions to participate in this thread. We all learn from each other.

edit:
This is a link to the blood work study done on oral cobalamin and injectable done on patients. It gets buried in this long thread so I am adding it here:

and this is the full article:

and this is a link to Dr. C. Snow MD's link on new treatment protocols for B12 deficiency:

this link is post 70 in this thread.

These two additions are easier now to find in this first post.

today 3-9-14
I had a very good video from YouTube on this portion of this post.... as of today... 3-9-14 it comes up as "private" only on YouTube. So I have removed the link. It was a great video...if it returns, I'll repost it.
