What is the primary mechanism by which hepcidin regulates iron metabolism in the context of anemia?

A By inhibiting the absorption of iron from the gut ✓
B By promoting the release of iron from macrophages
C By reducing the production of erythropoietin
D By increasing the expression of ferroportin

Explanation

Hepcidin plays a crucial role in regulating iron metabolism by inhibiting the absorption of iron from the gut and its release from storage sites, thus affecting the availability of iron for erythropoiesis.
