Welcome to ehealthforum.
RDW is elevated as the medications have helped with increase in hemoglobin levels and improvement in red cell count (appearance of new cells in blood will lead to elevated RDW). Continue with taking the supplements for another 2 months to replenish the depleted stores. For further clarification and assistance, visit your doctor/healthcare provider.
Take care.
