Research shows that iron supplements typically begin to raise hemoglobin levels within 2-3 weeks of consistent use. However, you may need to take them for 3-6 months to fully replenish iron stores. Progress indicators include:
- Increased energy levels (2-3 weeks)
- Improved exercise tolerance (3-4 weeks)
- Normal hemoglobin levels (6-8 weeks)
- Replenished iron stores (3-6 months)
Regular blood tests can monitor your progress. Continue taking supplements as prescribed even after feeling better to ensure complete restoration of iron stores.
