Does vitamin b12 increase iron levels

Yes, taking vitamin B12 can improve iron levels in your blood. Vitamin B-12 stimulates methionine synthase, an enzyme with several essential activities, including assisting your body in using folate, which is required to create new DNA during cell division.

Typically, roughly 1% of the red blood cells in your circulation are replaced by new cells each day, ensuring that the quantity of red blood cells in your circulation is always sufficient to give oxygen to your cells, tissues, and organs.

When you don’t get enough vitamin B-12, your useable folate levels drop, limiting the development of new red blood cells in your bone marrow. As old red cells wear out and die but aren’t adequately replaced, this condition might eventually lead to low iron levels in your blood.
