All the B12 info is already at PN here on the stickies.
There are so many discussions about B12 on NT, just about every forum at one time or other.
For B12 you need 400pg/ml or more. Anything less is problematic. The lab ranges reported for the serum test, are still outdated in the US.
Everyone is welcome to come to PN and read and ask questions there.
