Melody:

It's not understandable that most docs are several decades behind (or even misinformed for that era) on the most basic of B12 information.

However, it is understandable that most know nothing about methylcobalamin. One who specializes in neurological issues should, but everyday MDs have plenty else to keep up on and if they just knew some basics many many lives and mobilities would be saved.

I'm glad you didn't fall for the expensive B12.

B12 is absorbed in the ileum, but to be absorbed normally it requires sufficient stomach acid and intrinsic factor from the stomach. However, it would be extremely rare for a person who lacks both (or even lacks a stomach) not to absorb what they need to rebuild stores with daily supplements of at least 1000 mcg.

Most docs don't know that either, even though it made it into better medical textbooks in the U.S. many years ago (was shown by Swedish researchers about 40 years ago.
