Calcium and Iron Supplements: Why Timing Matters

Calcium and Iron Supplements: Why Timing Matters

If you take both calcium and iron supplements, you need to take them at different times.

This is because they use the same pathways to get into your body, so they can cancel each other out if taken together.

Calcium is best taken in the morning when your body is most active.

Iron is absorbed well after waking up when your body's iron is low.

Take these supplements before or a few hours after eating, when your stomach is empty.

If you need them, it could be because of a deficiency, pregnancy or certain health conditions.
