Considerations when supplementing iron and calcium
Foods rich in iron and calcium are abundant around us. However, for some specific groups, these sources of iron and calcium may not be sufficient. In such cases, using supplements to boost iron and calcium intake is essential. However, during supplementation, you need to be aware of certain considerations regarding iron and calcium.

Therefore, you should supplement iron and calcium at least 2 hours apart to ensure effective absorption.

Iron is best absorbed on an empty stomach, so take your iron supplement before a meal. After eating, you can then take your calcium supplement. Additionally, consider drinking orange juice to enhance absorption.
