Iron supplements are best taken on an empty stomach, ideally 1-2 hours before or after meals. According to clinical research, taking iron supplements with vitamin C can enhance absorption by up to 67%. However, avoid taking them with:
- Calcium-rich foods or supplements
- Coffee or tea
- Antacids
- High-fiber foods
If you experience stomach discomfort, you can take iron with a small amount of food. Morning consumption is often recommended as iron absorption tends to be better earlier in the day.
