Iron supplements are best taken on an empty stomach, about 1-2 hours before or after meals. According to research, this timing maximizes absorption. However, if you experience stomach upset, you can take them with food.
Tips for optimal absorption:
- Take with vitamin C (like orange juice) to enhance absorption
- Avoid taking with calcium, coffee, tea, or dairy products
- Space iron supplements 2 hours apart from antacids
For menstruating women, the recommended daily intake is typically 18mg, while pregnant women may need up to 27mg according to clinical guidelines.
