To optimize iron absorption:
- Take iron supplements on an empty stomach
- Combine with vitamin C-rich foods or supplements
- Avoid taking with calcium, coffee, or tea
- Space iron supplements 2 hours apart from antacids
Studies indicate that taking iron with 100mg of vitamin C can increase absorption by up to 67%. For best results, take iron supplements either 1 hour before or 2 hours after meals. If stomach upset occurs, you can take them with a small amount of food.
