Ferritin is a storage protein that lets your body access and use iron as it needs it.
And getting iron to move into ferritin is…complex.
Think of a busy intersection in front of an elementary school at school drop off time – with crossing guards, stop signs, parents in minivans…
and your iron molecules are the small children running everywhere.
If the supporting players aren’t there, aren’t coordinated, or aren’t able to get to their spot, the kids don’t get to school.
Most importantly: adding more kids (aka more iron) to the situation isn’t going to clear the intersection and get school started on time.β
