Iron supplements are best taken on an empty stomach, ideally 1-2 hours before or after meals. According to research, absorption is maximized when taken with vitamin C-rich foods or supplements. However, avoid taking iron with:
- Calcium supplements or dairy products
- Coffee or tea
- Whole grain cereals (high in phytates)
If stomach upset occurs, you can take iron with food, though absorption may be reduced by 40-50%. Morning consumption is often recommended as iron levels naturally fluctuate throughout the day.
