Blood test showed low iron saturation at 14%, normal 20-40%. only other abnormal lab was elevated b12 at 1297. i do take a b12 supplement because i was told years ago i was deficient. are these concerning??

Low iron saturation does not mean iron deficiency especially with normal RBC, Hb/Hct. TIBC and Ferritin level are required for the diagnosis of iron deficiency. You may be low in B12 in the past for many reasons and now it is over-corrected with supplement & diet? To continue or not depend on the dose you currently take, your dietary habit (not eating animal products), etc. Discuss with your doc.
