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. Factors affecting recovery time include:
- Initial severity of iron deficiency
- Dosage and type of supplement
- Consistency in taking supplements
- Overall health and absorption capacity
Most people notice improved energy levels within 1-2 months of starting supplementation. Regular blood tests can monitor your progress and determine when you’ve reached optimal levels.
