Thank you for this very informative article!

In all my years of "doctoring," I've never had a doctor (to my knowledge) check my B12 - until the Family Doctor that I now have who checks every patient, regularly.

During lab tests, last year, he discovered that my B12 was extremely deficient - to the point that I had to have weekly injections daily, for a week. I am now getting monthly B12 injections.

It's amazing what a difference it makes in one's memory!!
