5️⃣ Shared role in erythropoiesis and DNA synthesis
Inside bone marrow, folate and B12 cooperate to generate tetrahydrofolate, a cofactor for DNA and red cell production. Without them, cells enlarge without dividing properly, producing megaloblastic anemia.
🟢 Example: B12 deficiency traps folate in its inactive form (“methyl-folate trap”), halting DNA replication and leading to fatigue, pale skin, and neurological symptoms.
