Anemia has multiple causes, so diagnosis matters first. In iron-deficiency anemia, focus on increasing iron intake and absorption: red meat, fish, eggs; plant sources like lentils, chickpeas, beans, tahini, pumpkin seeds, spinach, and fortified cereals. Pair with vitamin C. If B12 or folate deficiency is involved, the strategy changes—so labs should clarify the anemia type before you build the plan.
