Iron supplements can help restore natural hair color that has changed due to iron deficiency anemia, as evidenced by the improvement in hemoglobin levels and iron absorption in patients with iron deficiency anemia 1. When your body lacks sufficient iron, it prioritizes essential functions like oxygen transport to vital organs over cosmetic features like hair pigmentation, which can lead to premature graying or lightening of hair. Common iron supplements include ferrous sulfate, ferrous gluconate, or ferrous fumarate, typically taken 1-3 times daily depending on the severity of deficiency. For best absorption, take iron supplements on an empty stomach, but if stomach upset occurs, they can be taken with food, as the addition of vitamin C may not be essential for patients with iron deficiency anemia 1. Avoid taking iron with calcium, dairy, coffee, tea, or antacids, as these reduce absorption. Hair color changes may take several months to reverse after iron levels normalize. Side effects may include constipation, black stools, and stomach discomfort. It's essential to have your iron levels tested before starting supplements, as too much iron can be harmful, and to address the underlying cause of your iron deficiency with your healthcare provider. The study by 1 suggests that oral iron supplements alone are equivalent to oral iron supplements plus vitamin C in improving hemoglobin recovery and iron absorption, which can help restore natural hair color. Key points to consider when taking iron supplements include:
- Take iron supplements on an empty stomach for best absorption
- Avoid taking iron with substances that reduce absorption, such as calcium, dairy, coffee, tea, or antacids
- Have your iron levels tested before starting supplements to ensure you need them and to monitor your progress
- Address the underlying cause of your iron deficiency with your healthcare provider to prevent future deficiencies.
