Iron supplements are best taken on an empty stomach, ideally 1-2 hours before or after meals. According to research, taking iron with vitamin C can enhance absorption by up to 67%. However, avoid taking iron with:
- Calcium-rich foods or supplements
- Coffee or tea
- Dairy products
- High-fiber foods
If you experience stomach discomfort, you can take it with a small amount of food. Best practices include taking iron supplements first thing in the morning or just before bed if you haven’t eaten for 2 hours.
