Here is a hypersegmented neutrophil that is present with megaloblastic anemias. There are 8 lobes instead of the usual 3 or 4. Such anemias can be due to folate or to B12 deficiency. The size of the RBC's is also increased (macrocytosis, which is hard to appreciate in a blood smear).

Question: What are some dietary sources of B12?

AnswerTissues from animals, particularly liver, have abundant B12. Dairy products and enriched cereals provide B12. Lacto-ovo-vegetarians can still get sufficient B12 with a varied diet over time, building 2+ years of reserve in liver stores.
