How long after taking iron pills for six weeks do i recover from symptoms of severe anemia.

Can take a while: If you were severely anemic because of iron deficiency, 6 weeks of oral iron is probably not long enough. Your body will start to be able to make new red blood cells much more robustly when you start taking the iron, and many people start to feel better in a week or two. To replenish your body's iron stores, however, you may need to take iron 6 months or more. Talk with your doc for guidance.
