What is suggested for a 52-year-old black woman, who is supplimented on iron and vitamin C for many years, when she was told that her RBC count has never completely normalized, O/E and other parameters are normal and Hb = 11.6 g/dL?

This patient has Hb 11.6 g/dL which is normal for an adult woman (normal range is approximately 12-16 g/dL, but 11.6 is acceptable and not true anemia). With normal O/E (likely meaning other parameters) and long-term iron supplementation showing no improvement, the issue is likely physiological variation or thalassemia trait. Continuing iron therapy risks iron overload and is unnecessary. Discontinuing iron is appropriate since there is no true deficiency.
