171: Does high B12 mean it’s not getting into the cell?

Masterjohn Q&A Files Episode 171

Introduction

Question: Does high B12 mean it’s not getting into the cell?

The right way to address that would be to measure serum or urine or both methylmalonic acid MMA, and that's a functional marker that's very specific to B12. If B12 was not getting into the cell, then methylmalonic acid is going to be high.
