Iron supplements are best taken on an empty stomach, ideally 1-2 hours before or after meals. According to research, taking iron supplements with vitamin C can enhance absorption by up to 67%. However, avoid taking them with:
- Coffee or tea (wait at least 1 hour)
- Calcium supplements or dairy products
- High-fiber foods
- Antacids
If you experience stomach discomfort, you can take iron with a small amount of food. Start with a lower dose and gradually increase it to minimize side effects.
