Just in the "for what's worth category,' there's a pretty common genetic mutation carried by about 20% - 30% of the population that results in better absorption of B12 and higher serum levels. I run high-normal and do have this mutation.
Additional studies have been run confirming this, but this abstract from 2008 was brief.

"Women homozygous for the rs492602[G] allele had higher B(12) levels."
