Iron Metabolism
Iron metabolism is how the body absorbs, stores, transports and recycles iron, which it needs to make hemoglobin, the red blood cell protein that carries oxygen. Copper has the clearest support among supplements, and trials found hemoglobin levels went up, with moderate evidence. That finding comes from about 250 participants, so it is a useful signal rather than the final word.
