The bone marrow and vitamin b12

Episode Overview

What does vitamin B12 have to do with the bone marrow?

Quite a lot.

In this episode, we explore the relationship between vitamin B12, bone marrow function, and normal blood cell development. Vitamin B12 is essential for DNA synthesis, which makes it especially important in tissues where cells divide rapidly, including the bone marrow.

When B12 becomes deficient, developing blood cells may struggle to mature normally. The result can appear throughout the hematology workup, from an elevated MCV on the CBC to distinctive changes on the peripheral blood smear.

This episode connects the physiology happening inside the bone marrow with the laboratory findings we can actually see and measure.
