                                According to numerous clinical reports, a vitamin B12 deficiency is a well-documented cause of low white blood cell counts, which includes a drop in neutrophils. While the vitamin itself does not cause this condition, a lack of it can severely impact blood cell production in the bone marrow, leading to neutropenia.
