Question on iron excretion ML.
For men, women who are past their menses stage, ( past menopause?) does donating blood help with the over abundant iron reduction?
How often would a person (see defining character definitions above) need to donate for it to be beneficial?
Yes, donating blood on a regular basis would help reduce iron overload. Unless you intentionally take in large quantities of iron (and why would you do that?), donating every month or two would be fine. So would giving chain saw lessons, but that's pretty messy.

The amount you get from a normal diet isn't likely to be harmful, but large doses via things like the use of cast iron for all or most cooking could definitely put you over the top. It would be much easier to stop (or not start) doing that than try to strain some of the iron out of your blood once it is there.

This might also be an issue for someone eating large amounts of red meat, along with a high protein diet otherwise. But I don't have any references for that. Just something to think about.
