Research indicates that iron supplements can interact with several medications:

  • Antibiotics (tetracyclines, quinolones)
  • Thyroid medications
  • Antacids and acid reducers
  • Calcium supplements

To avoid interactions, take iron supplements 2 hours before or after other medications. Always inform your healthcare provider about all supplements and medications you’re taking. For optimal absorption, avoid taking iron with calcium supplements or dairy products, as calcium can significantly reduce iron absorption.
