Does Grapefruit Affect Iron?

May affect absorption or how you feel

The short answer

Grapefruit's vitamin C content may actually enhance non-heme iron absorption. However, naringin can also chelate iron, making the net effect unpredictable.

How to arrange timing

Separate iron supplements from grapefruit by 2 hours to avoid unpredictable absorption changes.
