Raising hemoglobin depends on the cause. If iron deficiency is the driver, increase iron intake and absorption; if B12 or folate deficiency is involved, the approach changes. Nutritionally, use heme sources, legumes, seeds, and fortified foods paired with vitamin C. If hemoglobin is low—especially with symptoms like shortness of breath or palpitations—clinical evaluation is essential because blood loss or other conditions may be present. The best strategy is diagnosis-based and comprehensive, not a single “magic food.”
