Moderately low: Normal B12 levels for adults are 200-900 pg/mL. So 160 IS low. Also, many older adults will experience symptoms of deficiency even if the B12 is normal, but in low normal range. You must have been tested and learned that you lack intrinsic factor, a protein that helps the intestine absorb vitamin B12, or have other malabsorption issues, hence the need for injections.
