B12 Test Results

5/31/16: 151 pg/mL (Standard Range: 650-1340)

8/4/16: 1781 pg/mL (Standard Range: 211-911)


From 6/21/16 to now, my doctor has been giving me 1000mcg B12 injections every other week. In addition, I have been taking B12 orally (even though my doctor says that I cannot absorb it due to no intrinsic factor).

Question 1: How much is enough?

Question 2: How much is too much?

Doctor says I will have to be on B12 injections for the rest of my life. If so, I'm going to learn how to inject myself. People do this, right?

Thanks, all.
