I conduct lab tests for body checkup by blood samples every 6 months. My
B12 is consistently around 180-200 pg/mL range for last 3 yrs.
This time too B12 was around 200. My CBC also shows low RBC (4.08), high-normal MCV (100.9), high MCH (33.5) and elevated RDW (14.8), although Hb is still normal at 13.7.
I am a vegetarian, so may be miss out on B12 from other foods, thus consistently low B12 may be. What should I do to manage this? Should I take any supplementation?
