How does that work? How is iron absorbed in our gut or in our body?

Yeah.

Again, iron's a little bit unique because we don't regulate iron in a way that is due to the losses.

So what I mean by that is many nutrients, if you'll, or even if you think of sodium, when you lose sodium, you'll start to absorb more sodium and you may change how you lose it and how you sweat sodium out based on how your body needs it.

So there's a mechanism where it can stop being sweated out or things can change on the loss side of things to prevent deficiencies occurring.

Iron doesn't have that mechanism.

So iron losses are completely unregulated and they just occur as they want to occur.

If money is no object, perfect world, what would your next study be? What's something you're really looking for in a next study?
